3 Special pplications hain Special pplication hain igh Performance levator hains* Rexnord eavy uty levator chains have garnered a reputation as the longest lasting, most reliable chains available today for tough elevating applications. Our chains are the most efficient and reliable to elevate all types of material including clinker, finished cement, fertilizer, and coal. he 900 series chains are the newest addition to this line of chains. With larger components, the 900 series offers 30% greater fatigue strength over their 800 series counterparts. Lightening holes were added to the 900 series to offset the increased weight introduced by larger bushings and pins. No matter which series you choose, you re guaranteed the highest level of heat treatment and manufacturing available in elevator chains today. 800 Series R856 R857 R859 R Series R956 R958 R984 RN SL RINING RING ORY INSLL GRS RSILIN SL Sealed Joint levator hains actory installed grease sealed in, abrasives or corrosives sealed out. n option in these chains and denoted by the SJM prefix.

4 Special pplication hain Rexnord nd Link-elt ngineered hain pplication for musement Rides, Recreational Lifts, and Other People Movers Special pplications hain rom time to time, chain application questions concerning driving or conveying functions on amusement rides and recreational lifts are brought to Rexnord s attention. oncern arises for the safety and the well being of people utilizing these units should chains prematurely or unexpectedly fail. general review has been made to establish certain rules and recommendations for the selection and application of these rides and conveyances. he following reflects those conclusions: 1. hain should not be used for any amusement ride or recreational lift application unless there are adequate, functional, and operational safety backup devices to prevent hazardous or unsafe conditions from occurring. 2. hains containing castings or molded parts of any material should not be applied to these applications. his includes pintle, heavy pintle, combination, cast steel, nonmetallic, and similar chains. 3. ast or welded base chains should not be used in these applications. Welded attachments and other weldments used to augment an engineered steel base chain will be considered on a case by case basis. 4. pplications where a new chain selection is being made will only be considered for customers with qualified engineering expertise. hain selections of any nature should not be made or changed without written approval of the appropriate representatives of an approved Original quipment Manufacturer (OM) of that equipment. his includes replacement chains from any manufacturer including Rexnord. Requests involving like for like replacements will be considered for all customers. Written approval is required for each purpose. 5. hain selections for amusement rides or recreational lift applications should be of the engineered steel types of chain generally covered by NSI standards 29.10, 29.12, and after review of all application factors by and approval of the appropriate responsible representative of the original equipment manufacturer of the equipment. 6. hains on these applications should be adequately lubricated and properly maintained at all times. 7. hain reliability is based upon a good press fit of the pins and bushings into the sidebars. herefore, do not grind the chain pins, bushings, or holes in the sidebars in order to assemble the chain as supplied from the factory. 8. lteration of chain destroys the integrity of the press fits of the chain assembly. herefore, do not alter or rebuild any chains for these applications. 9. If a customer applies an engineered chain product without our approval, it is a misapplication and, as such, is not covered by warranty under our standard conditions of sale. Should questions arise covering any of these policies or procedures, please contact your local Rexnord sales representative. (5050) 5

29 rive hains rive hains ngineered Steel rive hains esigned to give you superior performance, even under the most punishing conditions Rugged, all-steel Rexnord and Link-elt drive chains are built to perform at levels other drive chains can t match. Rexnord began manufacturing drive chain in the late 1800 s and has been a leader in drive chain innovation since. oday s chains are a product of over a century of improved product design, testing and application experience. No one else in the industry comes close to our level of expertise. More built-in features for your money ngineered interference fit construction designed to increase chain fatigue life and wear life. State-of-the-art heat treatment of all chain components to assure longer chain life. Rexnord has developed most of its own heat treating equipment in-house for better control and to precisely fit the heat treat needs of drive chain pins and bushings. Pins, bushings and rollers are manufactured to exact tolerances. Sidebars and sidebar holes are punched using the latest punch press technology to give superior fit and finish. Selectively Induction ardened (SI) pins, available in many of our drive chains, afford you unmatched toughness and wear resistance. Ideal for tough, shock loaded applications. Stocked in the largest network of warehouses in the industry. ll backed up with extensive engineering and sales support. Smooth and precise, yet rugged. Our drive chains are able to handle applications from 1 to 300 plus horsepower. 30 (5050) Note: imensions are subject to change. ertified dimensions of ordered material are furnished upon request.

30 rive hains rive hains Wear life is directly affected by the hardness and case depth of the wearing components Selectively Induction ardened pins (the pin with the crescent-shaped hardened area) are heat treated only on the portion of the pin that experiences wear. he balance of the pin is left in a tough state to withstand shock loading. hain rollers, sidebars and bushings are all heat treated for wear resistance and strength. Pins hardened by Rexnord s advanced induction hardening process feature extremely hard wear surfaces and deep case depths as shown below. Ideal replacement for gearing, multiple strand roller chain, and belt drives. Requires less precision and expense than gearing as center distances are more flexible and adjustable. single strand of Rexnord or Link-elt drive chain can frequently replace multiple strand roller chain drives, thus simplifying maintenance. nd unlike multiple strand chains, our drive chains run on simple flame-cut sprockets. asily adjustable. he offset link design allows one link at a time to be taken out or inserted. No special connector links are required. Lower overhung loads than belt drives due to the elimination of pre-tensioning. Rexnord chains run best on Rexnord sprockets lthough our drive chains may be run on commonly available flame cut sprockets, they give better long term performance when matched with our sprockets. Our sprockets are flame cut and induction hardened to give hard, deep case depths. Most competitive sprockets have only a fraction of the case depth. Once the case depth is worn through, sprocket wear is rapid and chain interaction is affected, thus causing greater chain stress. I pins (right and bottom) offer very hard and deep case depths around the full circumference of the pin. SI pins (upper left) are hardened only on the load bearing surface so shock can be better absorbed by the back of the pin. Proprietary induction hardening process gives every heat treated sprocket superior case depths and hardness.

Our customers know that Rexnord chains provide superior strength and durability for extended wear life and trouble free service. Our years of experience provide unique expertise in material selection, heat treatment and chain design for improved chain strength and long wear life. What this means to you is superior value and greater productivity. he Rexnord Welded Steel Story lot goes into a Rexnord chain that is not visible on the surface. he precision of a diameter or the case depth of an induction hardened part can only be realized after an in-depth analysis. Rexnord regularly tests Rexnord and competitive chains. Not all welded steel chains are created equal. What follows is the story of how we make Rexnord Welded Steel chains to be the best - anywhere in the world. Maximizing hain Wear Life hrough Superior eat reatments hain wear life is directly affected by the hardness of the wearing components. Quite simply, the harder the parts, the longer the wear life. Rexnord s heat treatment technology exceeds that of other chain manufacturers. omputer controlled furnaces, and Rexnord designed induction heat treating equipment, produce chain components with the industry s hardest possible wearing surfaces and yet still provide the necessary toughness to resist shock loads. In addition, unique Rexnord process controls provide chains with consistent wear life. his allows users to predict the wear life of their chains, allowing for chain replacement as part of their preventative maintenance programs. In the end, superior chain eliminates costly and unexpected down time. ll Rexnord Welded Steel chains come standard with premium heat treatments. he photo (top right) shows a cross section of a Selectively Induction ardened (SI) chain pin. his exclusive Rexnord process involves super hardening only the portion of the chain rivet that wears as the chain articulates over the sprockets. he remainder of the rivet is held at thru-hardening levels cross section of a selectively induction hardened WX pin the crescent area is super-hardened to dramatically lengthen pin wear life. he balance of the pin material is left in the thru-hardened condition to give the pin excellent toughness. to assure chain toughness and resistance to breakage. his treatment is standard on WX Narrow Mill chains. Most manufacturers of welded chain compromise their design, either sacrificing component hardness or resistance to overloads. Rexnord Wide Mill heat treated chains (W) come standard with thru-hardened rivets, sidebars and barrels. Other manufactures short-change wear life by not hardening the barrels significantly reducing chain wear life. he table below illustrates the importance of superior heat treatment. y using the table, one can predict the increase in wear life by upgrading the heat treatment. s an example, increasing hardness from 35R to 60R could provide up to double the chain life.

If you regularly replace chains due to sidebar wear, you should select SI sidebars. his is a very cost effective way to increase your chain life. Selectively Induction ardened Sliding Surfaces nother key factor in providing maximum chain strength is proper welding, stress relieving, and heat treatment. Improper controls and processes can lead to failures around the weld either from improper weld penetration or by causing high hardness zones that result in brittle failures. Rexnord uses the latest technology in process and quality controls to assure proper weldments. Rexnord welded links are regularly tested during each manufacturing lot to assure our process is in control, producing high quality welds. he photo below shows a welded steel link that has been destructively tested to assure the strength and penetration of the weld. s demonstrated in the photo, the chain material failed first, not the weld. his demonstrates a high quality weld. Welded Steel hains Selectively Induction ardened sidebars can be ordered to give greater resistance to abrasive sliding wear, thus providing greater sidebar life. o extend wear life in specially corrosive applications, Rexnord Welded Steel chains can be provided with a variety of plating options or with stainless steel components. ontact Rexnord for application assistance. Let us put 100 years of experience to work for you. Maximizing hain Strength key factor leading to the durability of Rexnord welded steel chains is superior fatigue strength. Rexnord Narrow Series Welded Steel chains have tightly controlled, interference fits between the pin and chain sidebar hole. his interference fit creates a beneficial residual stress in the sidebar to greatly increase the fatigue life of the chain. he chains have a stepped (3 diameter) pin to ease assembly and protect the integrity of the interference fit. ompetitive chains with poorly controlled interference fits (or with clearance fits) have much lower fatigue strength. Low fatigue strength chains are subject to unexpected chain failures after a chain sees many cycles of loading. Rexnord s quality assurance program requires welded steel links to be tested for weld strength and penetration. Maximizing Plant Productivity Rexnord brings years of application and design experience and an extensive offering of quality chain, bearings and other fine power transmission components. Our sales people and application engineers are eager to work with your organization to maximize the productivity of your plant. Please call us for any assistance we might offer. (5050) 37

39 Welded Steel hains Welded Steel hains Reverse arrel Wide Mill rag hains simple and effective solution for an old problem. he Problem: Since their introduction, wide mill welded steel chains were designed to run narrow or closed end forward. his is the direction of travel that the chains on the preceding page run. Running in this direction, an offset sidebar chain will experience scrubbing between the outside of the chain s barrel and the drive sprocket s tooth (igure 1). On shorter conveyors, where the chain frequently contacts the sprocket, this scrubbing can cause rapid wear of both the chain and sprocket. his scrubbing may not cause as much chain wear on longer conveyors but it will still cause sprocket wear. he Solution: Rexnord engineers realized that if they reversed the barrel of the chain so it could run in the opposite direction, wide or open end forward, the scrubbing action could be eliminated. Instead of the articulation occurring between the outside of the chain barrel and the sprocket tooth it occurs inside the chain joint between the pin and the barrel (igure 2). his arrangement is preferable since both the pin and the barrel of the wide mill chains are heat treated to withstand this type of wear. ow do I Know if I Need Reverse arrel hain? Note the difference in position of the pin within the barrel in igures 1 and 2. When running narrow end forward and the engaged pin is being pulled forward at the time of engagement and the pin of the previous link is being pulled against the front of the barrel. When reverse barrel chain is run wide end forward (igure 2), the sprocket is pushing against the force applied. his may extend the useful life of chains used in long and/or heavy loaded applications where the typical mode of chain failure is breaking at the barrel welds. rticulation is etween hain arrel and Sprocket ooth igure 1 rticulation is etween Pin and arrel igure 2 IRION O RVL G IN PI Rexnord hain No. verage Pitch hickness Sidebars eight Pins G imensions are in inches.

40 Welded Steel hains eavy uty Welded Steel rag hains Rexnord eavy uty drag chains are ideal for conditions where severe abrasion and heat exist. hey offer these important features and benefits: ardface welding on both of the chain s sliding surfaces is standard. typical weld hardness of 60 R and a heavy weld bead give this chain excellent sliding wear resistance in cold and hot clinker applications. Interference fits between the pin and chain sidebar dramatically improves chain strength and joint wear life over that of a cast drag chain. In addition, this eliminates loose pin movement in the chain joint. n induction hardened pin affords the best of two worlds a 60 R typical hardened case and impact resistant material in the core of the pin. he result is longer service life and superior resistance to shock loads.

41 Welded Steel hains Welded Steel hains ttachment Welding Instruction 1. Surfaces to be welded should be clean and free of foreign material. It is not necessary to remove the prelubricant before welding, however, proper ventilation is mandatory. 2. Weld strength should be sufficiently high to cause failure of the parent metal and not of the weld itself. 3. Welds should be free of cracks, undercutting, slag, inclusions, and excessive porosity. raters due to stop welding should be located away from corners and edges; most craters contain slight cracks which can initiate failures at high stress areas. 4. Weld beads should be free of pinholes, have uniformly fine surface ripples, and have little or no indication of where a new piece of filler metal was started. 5. Weld edges should indicate complete fusion without overlap or undercut. 6. Welds should be clean, free of spatter, slag, excessive oxides and arc scars. 7. rcs should be struck on attachments, not on the sidebars. rc scars on sidebars can produce early chain failure. 8. onvex shaped weld beads are preferred. onvex fillet welds are strong and less subject to cracking than concave forms. 9. lectrode selection is very important. n electrode that has been successfully used is 7018 (70,000 psi tensile strength, low hydrogen). his rod is for all position use, or. Good welding practice dictates that electrodes be stored in a dry atmosphere or baked prior to use. Specific electrode manufacturer recommendations should be closely followed. 10. Preheating and Postheating eat applied to the weld heat affected zone is always beneficial. hese processes, while not generally required for small attachments, are recommended for large or heavily loaded attachments such as Styles & log cradles. No welding should be performed on parts below 70 o. eating is usually done by use of a neutral flame to heat the parts prior to or after welding. Preheat: Performed to reduce possibility of weld cracking both surface and subsurface. Parts to be welded link and attachment should be heated uniformly to 300 o. Postheat: Performed to relieve internal stresses and to reduce weld zone hardness. eat affected zone of weld heated to 700 o. 11. ack welds should never be used in areas that will not be welded in the finished product. WL LG Preheating and postheating may be required see (10). ZON WL LG aution No welding should be performed on or immediately adjacent to an induction hardened or carburized part. Welding to an induction hardened part can produce tempering and softening of this hard surface. Welding attachments to the carbon rich surface of a carburized part will result in brittle welds and possible cracking. 42 (5050) Note: imensions are subject to change. ertified dimensions of ordered material are furnished upon request.

51 ast hains ast hains SM ombination hains SM ombination chains are designed primarily for high temperature applications and are extensively used for conveying steel sheets or bars through normalizing and heat-treating furnaces. he chains usually operate in channels under the floor and are thus protected from full exposure to furnace heat. he conveyed material is pushed through the furnace by fingers attached to the center links of the chain. he center links and sidebars are well proportioned for strength and rigidity. Sidebars are cast with bosses which fit into sockets in the center links. his design interlocks the center links and sidebars and relieves the pin from handling the entire working load placed on the chain. Sidebars and center links are cast. Steel pins are heat-treated. hey are free to float in the chain joint. his permits pin rotation, thus exposing the entire pin circumference to wear. It also helps correct pin bending that might occur as a result of high temperatures. he pins extend on each side of the chain to provide a mounting for outboard rollers. Rollers rotate freely on case-hardened steel bushings and are held in place by cast washers. learances between all moving parts are carefully controlled by machining, to prevent binding during operation at high temperatures. osses on sidebars fit sockets in center links to reduce stress on pins.

65 Sprockets Sprockets Sprocket ypes Sprockets can be supplied in various materials and styles, depending upon the application and severity of service requirements. or most engineered chain applications, fabricated steel sprockets are recommended as offering the best combination of performance, availability, and price. abricated steel sprockets can be provided for every chain- tooth combination and are readily available. Sprockets can also be supplied in various cast materials, with or without hardened teeth. he cast sprocket tables present the available patterns for producing cast sprockets. Whatever the types selected, our sprockets are designed for proper chain-sprocket interaction. Rexnord engineers have selected the proper tooth pressure angle, pitch line clearance, bottom diameter and tooth pocket radius for optimum performance and service life. Sprocket Styles ast rm ody his type of sprocket is generally used where larger sizes are required. he use of arms reduces weight, facilitates handling, and lowers cost. ast Split (rm or Plate) ody he split body design facilitates mounting and removal from shafts without disturbing bearings or other connected equipment, which greatly reduces installation and downtime. ast Plate ody Plate bodies are generally required for the smaller sizes where the use of arms is impractical, and on larger sizes when the chain pull exceeds the strength of the arm body sprockets. abricated Steel Sprockets abricated steel sprockets are flame cut and manufactured from plain carbon steel. he teeth are flame or induction hardened. Shear Pin sprocket is modified by the addition of shear pin hubs and shear pins. hey are used in applications where jamming or overloading is prevalent. he shear pins are designed to transmit the required torque under normal operating conditions, but to fail when an overload or jam occurs, thus protecting machinery and equipment from damage. Special Sprockets Sprockets can be made of special design, such as flanged-rim (used particularly in the rock products and fertilizer industries). Long-tooth or gappedtooth sprockets can also be made. ast Sprocket rm ody abricated Steel with Lightening oles Shear Pin Sprocket ast Split rm ody abricated Steel Split Sprocket rum langed rm ody Sprocket ast Steel Plate ody abricated Steel Plate ody langed Rim Sprocket Segmental Sprockets and raction Wheels an be supplied with either solid or split bodies, and have removable and replaceable sprocket segments or traction wheel rims. Rims are made of specially hardened steel for superior wear resistance. ccurate machining and precisely drilled holes permit sprocket segments to be reversed, thus doubling sprocket life and minimizing downtime. Segmental Sprocket with Split ody Segmental raction Wheel with Split ody raction Wheels Primarily designed for single-strand bucket elevator service, traction wheels can also be used on other type conveyors providing the coefficient of friction is sufficient under normal load to allow the traction wheel to drive the unit. distinct advantage of a traction wheel is that the chain will slip on the wheel in the event of an obstruction or overload, thereby preventing damage to elevator or conveyor components. raction wheels are ideal for service in abrasive environments since there is less scrubbing of the chain on a traction wheel as compared to sprocket. 66 (5050)

66 Sprockets Selection, Specification and Ordering Information Number of eeth Sprockets preferably should have no less than 12 teeth, particularly if speeds are high and the chain loads great. Sprockets having less than 12 teeth should be adapted only to slow and medium speeds. he number of teeth and sprocket speed (revolutions per minute) control the amount of impact of the chain seating on the sprocket. Impact is reduced as the number of teeth is increased or as speed is decreased. Likewise the chain pull is reduced as the sprocket size is increased for any one power drive. onsequently, a lighter chain - for greater economy - may often be used. With a greater number of teeth angular motion or friction in the chain joints is reduced. eight of eeth eight of teeth for standard sprockets is generally based on providing a working face that will accept the maximum amount of wear elongation combined with a smooth topping curve. further limitation that takes precedence over the above is that when a sprocket series is capable of being used with chains designed for conveyor/elevator service, the top of the tooth of all standard sprockets having ten or more teeth is designed to be low enough to clear a slat or carrier mounted on the lowest possible K attachment of any chain using sprockets of that series. s a precaution, it is recommended that orders for sprockets specify whether it is necessary for the top of the tooth to clear any slat, bucket or carrier mounted to a chain attachment, or welded to the chain. ore and ub Size he size of the bore and hub are determined by the torque to be transmitted. he hub specification charts included in this catalog provide selections based on a design shear stress of 6000 psi, maximum. Gapped Sprockets Some attachments require gapped sprockets to avoid interference between the sprocket and chain or assembled fittings. Such attachments usually are those wherein the space between sidebars is utilized by the attachment or its fitting. he gap spacing must be a multiple of the particular attachment spacing in the chain, also of the number of teeth on the sprocket. When some teeth must be topped off (that is, omitted) as distinguished from gaps that extend within the root diameter, it will be assumed that topping off the teeth flush with the root diameter will suffice to clear the obstruction. If gaps are required, complete details must accompany the order. eat reatment abricated steel sprockets are normally supplied with induction hardened teeth. ast sprockets, if hardened, are either induction hardened or cast as chill iron. he catalog cast sprocket tables identify cast sprockets with hardened teeth. Rexnord takes an extra step when heat treating segmental sprockets and tractions wheels to provide the utmost in hardness and case depth. Prior to induction hardening, segmental rims are soaked with carbon in large carburizing pits specifically designed for this purpose. he carburizing process provides deep penetration of carbon into the segment s working surfaces, thereby increasing its hardenability. fter the carburizing process, the segments are taken to induction heat treat area where the segments are enveloped in a large electrical coil, heated to a cherry red, and quickly quenched. his final process produces the hardest, deepest cases available in an engineered sprocket or traction wheel today. he carburizing/induction heat treatment process is standard for most of our segmental sprockets and traction wheels. If you have issues with extreme sprocket wear, this extra step may be the solution. ontact Rexnord to find out if this process is available for your particular sprocket type; not all sizes and styles are available. Relative depth of hardened material developed from flame, induction or chill rim hardening methods. Relative depth of hardened material developed through the two-step carburizing/ induction hardening process used in our segmental sprockets and traction wheels. More hardened material means longer sprocket and chain life. Sprockets (5050) 67

Keyseat and Keyscrews Standard straight keyseats on the centerline of a tooth are finished with one setscrew over the keyseat and one at 90 o. Multiple Sprocket lignment On a multiple strand conveyor or elevator, it is important that driving sprocket teeth be properly aligned in service. It is recommended that drive sprockets be ordered in sets with keyseats properly located relative to the teeth. Sprockets ordered as matched sets will be match marked. Sprockets are to be installed such that all match marks face the same end of the shaft. t the tail end of a multiple strand conveyor, only one sprocket should be fixed (keyed or set screwed) to the shaft. he remainder of the tail sprockets should be allowed to turn freely on the shaft to compensate for differences in strand length that may change over time.

In addition, the traction wheel will minimize peak chain tensions under impact or starting conditions. Successful application of a traction wheel is dependent upon the frictional force between the traction wheel and the chain bushing. he friction is great enough to handle the applied chain load without excessive slippage. actors which can detract from the effectiveness of a traction wheel are: 1. andling material with lubricating qualities. 2. eavy digging loads. 3. andling very dense material. ry and abrasive materials, on the other hand, have the desirable effect of increasing the coefficient of friction. raction wheels have been used very successfully in the cement mill industry. hain with rollers should not be used with a traction wheel.

83 Sprockets Sprockets Segmental Rim Sprockets nd raction Wheels (ont d.) ast Rims ach traction wheel rim and sprocket rim are induction case-hardened to the highest practical hardness around the entire circumference. he hardness depth is controlled to give the longest wear life, yet leaves the interior tough and ductile perfect qualities for absorbing the impact and shock loads encountered in elevatorconveyor service. Segmental sprocket rims can be reversed (back side of tooth becomes the working face), in order to maximize wear life. Segmental traction wheel rims can be easily installed, no need to even remove the chain in order to replace worn out rims. No burning or cutting is necessary. Our head traction wheel design moves the center of the chain load more closely over the body flange, thus reducing the possibility of hub fatigue problems. Segmental rim traction wheels are split with cuts in the rims that are made diagonally. hese diagonal cuts eliminate the possibility of the segments spalling or chipping at the line of split as a result of chain bushing or barrel line impact. he sides of the segmental traction wheel & sprocket rims are chamfered to allow the chain to enter and leave smoothly without damaging the chain components. ll rims are furnished with high strength UN thread nuts and bolts as standard. hamfered for smooth interaction w/chains Sprocket Rims Sprocket ross Section Rex -head raction Wheel ross Section raction Wheel Rims vailable ast raction Wheel Rims (with olts, Washers and Nuts) Rexnord hain No /2 S102 1 /2 S102 S R111 Link-elt hain No /2 SS102 1 /2 SS102 SS SS111 Outside iam.

86 esign and Selection Selection Of hains he following sections of this catalog are devoted to presenting comprehensive selection procedures for drive, conveyor, and elevator chains. he information included provides economical selections, yet assures the correct choice of components which can withstand the rigors of the application. ecause there is an almost unlimited variety of component applications, these selections are meant only to serve as a guide when designing new systems. On existing installations, the selection guides will prove helpful in determining whether a component in use is the most economical choice. hey will also serve to guide the upgrading of present installations where service life is not satisfactory. Rexnord Selection Services Rexnord application engineers are available to assist in the selection of chains and components. Gather all pertinent technical information regarding the application, and call us at (414) or fax us at (414) hain Ratings s a result of extensive testing and field experience, load ratings have been established for drive chains based on wear durability and fatigue strength to provide 15,000 hours chain life under the ideal conditions of clean environment, proper installation, maintenance, and lubrication. rive chains are selected in the tables by horsepower and speed. ll other types of metal chains should be selected based on working load and chain speed limitations, with due regard for experience in similar application environments. chain s working load is the maximum load (chain pull) a chain can withstand without a shortened life due to accelerated wear or breakage. Rexnord and Link-elt chains are also rated according to the Standards and Policies and Procedure Recordings of the merican hain ssociation. Most notably, we publish a minimum ultimate tensile strength (MUS). his represents the minimum force at which an unused, undamaged chain could fail when subjected to a single tensile loading test. It should be noted that chains should not be selected based on ultimate strength ratings. esign considerations chosen to maximize ultimate strengths frequently are not consistent with obtaining the best possible resistance to the modes of failure that most often limit a chain s life (e.g. low-cycle fatigue, corrosion induced embrittlement, etc.). hains that sacrifice some degree of tensile strength to obtain greater ductility, toughness, and resistance to embrittling conditions are far better suited to most application environments. rive hain Selection Rexnord and Link-elt drive chains of all steel construction are ruggedly built, dependable chains for service in the slow to moderate speed ranges and heavy loads. Since they operate over cast sprockets with hardened teeth or fabricated steel sprockets, and are long in pitch compared to NSI roller chain, they are a more economical choice than other chains. Under exposed conditions, or where dust and dirt are present, the designed, built-in clearance between the working parts of our drive chains make them very suitable for service. onveyor and elevator drives are ideal for Rexnord and Link-elt drive chains since they withstand heavy shock loads and exposed operating conditions. Rexnord 3100 Series steel chain is designed to have advantages and features of our other steel chains and to be a replacement for NSI roller chains. Rexnord and Link-elt drive chains are not designed for attachments. See pages 10 to 29 for chains with attachments. General esign onsiderations asis for Selection Selections are based on laboratory tested and field proven horsepower capacity and speed data rather than working loads. he horsepower capacity ratings have been developed on the basis of fatigue strength and wear capacity of the chain components. Under ideal conditions of clean environment, proper installation, maintenance, and lubrication, the selections listed are intended to provide 15,000 hours chain life for 100 pitch strands. More economical chain selections are available. or applications where a chain life of less than 15,000 hours is acceptable, contact your Rexnord representative. conomy When selecting a chain drive, consider all elements, but use only those that are required for the safe and successful operation of the drive application. In evaluating the economy of a chain-sprocket drive system, consider the overall cost of the chain and sprockets in the system and not merely the cost per foot of chain. hain he best chain and sprocket combination is selected in the 12-tooth column. Occasionally, the same chain will appear under the three sprocket selections; that is 9, 12, and 15. his same chain is the most economical choice of all the other chains that were considered. Selection for 9-tooth sprockets are limited, in some cases, by commercial steel shafting. Where alloy shafting is required, see Rexnord for recommendations. (5050) 87 esign and Selection

87 esign and Selection esign and Selection Sprockets Rexnord sprockets are designed with full attention to the requirements for proper chain-sprocket interaction. or each size and type of sprocket, Rexnord ngineers have selected the proper tooth pressure angle, pitch-lineclearance, bottom diameter and tooth pocket radius for maximum service. abricated steel sprockets are recommended as the preferred choice for all chain drives. ast sprockets with hardened teeth are also available for use on slower drives. Largest Keyseated ore he largest keyseated bore shown in the drive chain selection tables (pages ), indicates the largest shaft that may be used with the sprocket hub selected. Sprocket hubs will deliver the P and RPM used for the selection but are not designed for the torque that could be delivered by the largest keyseated shaft shown in the table. If a larger bore than shown is required, select a larger sprocket. he largest bore is selected from the hub size table for the material shown, either ast Sprockets with hardened teeth or abricated Steel, and defines the largest hub diameter which will fit without interfering with the chain. hain Slack or best operating service, allow a sag in the slack strand equal to 3% of sprocket centers. rive rrangements Relative position of sprockets in drives should receive careful consideration. Satisfactory operation can be secured with the centerline of the drive at any angle to the horizontal, if proper consideration is given. ertain arrangements require less attention and care than others are, therefore, less apt to cause trouble. Various arrangements are illustrated in the diagrams. he direction of rotation of the drive sprocket is indicated. est rrangements rrangements considered good practice are illustrated in igs. 1, 2, 3, and 4. he direction of rotation of the drive sprockets in igs. 1 and 4 can be reversed. Other cceptable rrangements If none of the above arrangements can be followed, an attempt should be made to use an arrangement as illustrated in igs. 5, 6, and 7. ig. 5 ig. 6 ig. 7 When the large sprocket is directly above the small sprocket, ig. 8, a drive cannot operate with much chain slack. s the chain wears, shaft-center distance must be adjusted or an idler be placed against the outside of the slack strand (near the small sprocket) to adjust slack and keep the chain in proper contact with the small sprocket. With the drive slightly inclined, ig. 5, less care will be required, because the weight of the slack chain strand helps to maintain better contact between the chain and the sprockets. Where center distances are short, or drives nearly horizontal, the slack should be in the bottom strand, especially where take-up adjustment is limited, ig. 6 rather than ig. 9. n accumulation of slack in the top strand may allow the chain to be pinched between the sprockets, ig. 9. When small sprockets are used on horizontal drives, it is better to have the slack strand on the bottom, ig. 7, rather than on the top, ig. 10. Otherwise, with the appreciable amount of slack, the strands may strike each other. Least Recommended rrangements ig. 9 ig. 2 ig (5050) ig. 1 ig. 3 ig. 4 ig. 10

If the shaft has already been determined, use the bore size column to select the appropriate hub dimensions. Note: abricated steel sprockets with induction hardened teeth are the recommended first choice for drive applications but, if a cast sprocket is desired, be sure to check availability of the cast pattern as listed beginning on page 74.

102 esign and Selection onveyor hain Selection Procedures onveyor lasses consideration closely related to the type of conveyor chain is the conveyor class. Six conveyor classes have been established on the basis of friction factors involved with the movement of the chain (sliding or rolling) and the movement of the material (sliding or carried). hese six classes are described in terms of chain and material movement in the following table: onveyor lasses lass hain Material 1 Sliding, with flights Sliding 1 Sliding, without flights Sliding 2 Rolling Sliding 3 Sliding arried 4 Rolling arried 4 Supplemental Roller arried Other rrangements Other methods of supporting the return run are shown in the following illustrations. hese methods of support will result in faster chain wear because of the additional flexure at the joints in the return line and the higher pressure between the chain and the return support because of the small area of support. Return Strand Supported by Rollers esign and Selection asic onveyor rrangements here are several basic conveyor arrangements. he recommended arrangement (see illustration) is with the drive at the head end and with the carrying and return runs well supported. Note the catenary sag in the return run at the head end. In general, the catenary sag should be at least equal to 3% of the span over which the chain is hanging. he illustrated arrangement offers two advantages: he catenary force tends to keep the chain engaged on the drive sprocket. Wear at the chain joints is minimal because the return run is under minimum tension and flexure at the chain joints is reduced by the well-supported return line. If a take-up is used to adjust the center distance and maintain the correct catenary sag, be extremely cautious not to impose excessive loads on the chain. Return Strand Supported by Shoes onveyors sometimes are driven from the tail end as shown in the following illustration. his arrangement is not recommended for two main reasons: hain wear at the joints is greater because chain is flexing under load at both the head and tail sprockets. xcess chain tends to accumulate on the carrying run just after the tail sprocket and the resulting wedging action can cause the chain to jump the sprocket.

103 esign and Selection esign and Selection Method of hain ravel nother basic consideration is whether the chain will slide or roll. In deciding on the method of chain travel, the following points should be evaluated: hain Sliding arrying Loads of Rollers basic consideration on conveyors using chain with rollers is the load imposed on the chain. his load includes the weight of the slats or flights, and the weight of the material being carried. his load must be limited so that the pressure of the bushing on the roller is kept within permissible limits. Simple in construction, fewer moving parts and usually the lowest in cost for a given load. Most effective in dirty applications. Greater horsepower required. hain Rolling Smoother operation, less pulsation. Lower friction which permits longer centers, smaller motors, and lower operating costs. Not suited to dirty applications, foreign matter jams rollers. Less horsepower required. onveyor Pulsation nother consideration is the amount of pulsation that can be tolerated in the conveyor. his will vary from one installation to another and the permissible amount is a matter of judgement. When pulsation must be minimized, consider the possible causes and remedies listed in the following table: Possible ause xcessive friction onveyor too long onveyor speed too low (10 PM or less) Velocity fluctuation caused by chordal action Remedy lean and lubricate moving parts. Use shorter conveyor sections. Increase conveyor speed, or use non-metallic bushed chain. Use drive sprocket with 12 or more teeth, or use compensating sprocket. (ontact your Rexnord representative.) he table below lists allowable bearing pressures between bushings and roller. Note the method of determining the roller bearing area. he listed bearing pressures are for ideal conditions, i.e. slow speeds in non-gritty service with lubricated bearings. s any of these conditions become more severe, the allowable pressures must be reduced accordingly. he allowable working bearing pressures, in pounds per square inch between rollers and bushings, are approximately as follows: Roller and ushing Materials in ontact llowable earing Pressure P.S.I. ase-hardened steel against case-hardened steel 1400 ase-hardened steel against white iron 1400 ase-hardened steel against untreated steel 1200 ase-hardened steel against cast iron } = Roller-bore diameter pplies also to = Roller hub length outboard rollers.

104 esign and Selection onveyor hain Selection Procedures (ont d.) Wear Strips and Ways Generally, it is desirable that the chain wear slower than the wear strips or liner since it is the more critical and expensive part of the conveyor components. herefore, the most compatible wear strip should be considered after the proper chain has been selected. onveyor may experience wear even with the chain rolling instead of sliding. his wear is not a critical consideration but cold finished steel should be used for best operation. he subject of wear is extremely complicated and influenced by many factors. It is impossible to predict with accuracy the wear life of various chain liner combinations. his is due to the effect of many variable and uncontrollable factors such as abrasion, corrosion, lubrication, load, speed, and break-in period. hus, prior experience of a successful chain liner combination for a specific application is the best guide to predict performance. or new installations, where no previous experience can be applied as a guide, a metal liner should be used where chain is slightly harder than the liner. his will protect the chain by ensuring the liner wear first. he material should be at least comparable to the chain in surface finish or smoother. Non-metallic materials such as wood and plastic are occasionally used as liner materials. hese may result in wear strip economy, but should not be used where severe impacting loads exist or under extremely dirty conditions. If wear is a problem, neglecting the effect of corrosion, experience has shown that generally by increasing the hardness of either the chain or the metallic wear strip in an abrasive environment should decrease the wear on both. Lubrication, even if only water will reduce wear. Some general comments to insure proper installation of liners in the conveyor and things to do before start-up are: 1. See that the joints on the liners and frame are smooth so that no sharp edges protrude. 2. ake reasonable care in eliminating welding slag, weld spatter, metal filings and/or mill scale from the conveyor. 3. reak in chain and liner by operating the conveyor without load, and with plenty of lubricant, for a short period of time (generally 8-24 hours) or until the mating wear surfaces are polished smooth.

105 esign and Selection esign and Selection his procedure is intended to serve primarily as a guide for selecting a general type, or class, of chain when a new conveyor is designed. When following the step-bystep instruction outlined, the user may find that more than one type of chain will fit the particular conveyor requirement. In such a case the final selection of the chain may be affected by such factors as allowable sprocket diameters, space limitations for chain, chain pitch, and many other environmental and design factors peculiar to the particular conveyor being designed. ontact your Rexnord representative for assistance in selecting the best chain when a choice of more than one class is indicated. Parts of this section will prove useful in determining whether the chain on existing installations is the most economical choice, and will also serve as a guide to upgrading existing installations where service life is not satisfactory. Procedure here are six basic steps in selecting the proper type of chain for a conveyor installation. 1. etermine the class of conveyor. 2. stimate the total chain pull. 3. etermine the design working load. 4.

Short conveyor centers and high chain speeds produce rapid joint wear and chain elongation. hese conditions suggest a chain with a high ( or ) wear rating. c. eavy loads produce rapid sliding and rolling wear. hese conditions suggest a chain with a high ( or ) sliding or rolling wear rating. d. onveyors operating in highly abrasive surroundings require hard bearing surfaces. his condition would suggest a steel chain. e. Mildly abrasive or moderately corrosive conditions may indicate that a cast chain is the economical choice. f. orrosive atmospheres reduce the fatigue strength of component parts. In this case, chain with armor cased pins are recommended. g. he chain pitch may be dictated by the required spacing of attachment links. longer pitch is more economical while a shorter pitch requires less room for sprockets. In many cases a 4 to 6 pitch chain is considered a good compromise. h. he selection procedure outlined is applicable only if temperatures of the chain will remain within -40 o and +350 o. Special lubricants may be needed above 250 o. If these temperature limits will be exceeded, contact your Rexnord representative. dditional factors such as sprocket availability and price, chain delivery lead time and chain price should also be considered in making the final choice. In making the final selection reliability should be a primary consideration. ast chains, in general, do a good job in sliding applications and have excellent corrosion resistance. owever, in critical applications where overloads may be encountered, ngineered Steel and Welded Steel chains will usually provide longer and more dependable service. It is recommended, therefore, that the final selection be made from the listings of ngineered Steel and Welded Steel chains.

Since a rolling chain also has less friction, smaller drive units could be used, at lower operating costs. herefore, tentatively pick a chain with rollers to run on the existing trough. lso tentatively figure on using the available 10 x 27 steel flights and attachment wings. he basic conveyor cross section might become a two-chain conveyor with scraper flights connected between the chains as shown in the following sketch. 110 (5050) f 1 = oefficient of friction chain rolling on runway f 1 = fr da (See able, page 123) dr f 1 = 0.20 (his factor will range from 0.10 to 0.20, depending upon the chain roller-bushing proportions. Since the chain pull is only being estimated at this point, use the highest range 0.20 in the first calculation.) M M W S = Weight of material handled per foot of conveyor = P x 33.3 = 170 x 33.3 = 56.6 Lbs./t. S 100 = Weight per foot of moving conveyor parts = onveyor speed (feet/minute)

Since the weight of the chain and attachment links has not yet been determined, use the empirical factor given on page 107 to establish chain weight.

Step 4. Make entative hain Selection Refer to the chain selection chart and note that an engineered steel roller type chain is recommended for a lass 2 onveyor. Refer to pages of the chain listing section and note that these chains all have rollers. or the conveyor arrangement tentatively selected, a Style R chain, whose rollers are larger than the sidebars, should be used. s indicated in the selection procedure, Step 4-g. (Page 109), a 4- to 6-inch pitch chain is good first choice. lso, from the calculation of esign Working Load, a chain having a working load rating of 2548 pounds or greater will be required. hecking the chain listings, you will note a number of Style R chains in the desired pitch range. SR196 would be selected as the chain that most closely matches the desired working load. hains such as 2188 and 1604 have working loads substantially higher and would not be economical choices. SR196 would be the tentative selection. Step 5. Make entative Selection of ttachment Links rom the basic conveyor arrangement decided upon, an attachment lug which projects on one side of the chain only is required. lso, it is desired to select an attachment link to which the available flight wings can be adapted, if possible. his suggests a single - attachment lug such as the attachment. he 1 (single hole) attachment is available for the SR196 chain. Make this the tentative selection. Step 6. Verify hain Selection & Recheck esign Working Load he exact chain and attachment link weight per ft. can now be used to calculate the esign Working Load. lso, the chain roller and bushing diameters can be used to determine the chain friction factor (f 1 ). hain Weight SR196 Plain hain = 5.0 Lbs./t. SR196 1 ttachment Link = 6.6 Lbs./t. he weight per foot for the attachment link is based on a link interspersed every pitch. or the conveyor arrangement to be used, an attachment link will be required every 2 feet, or every 4th pitch (6 inch pitch chain). 3 plain links at 5.0 Lbs./t. = 15.0 Lbs. 1 ttachment link at 6.6 Lbs./t. = 6.6 Lbs Lbs = 5.4 Lbs./t.

Likewise, the round shank of a pin with locking flats on the cotter end will not pass through the slotted cotter-side sidebar hole. ield Repair When repairing chains in the field, the repair should be confined to replacement of complete links or sections. Replacement of individual components (bushings, rollers, etc.) is generally not recommended. herefore, this connect-disconnect discussion has been limited to removal and replacement of connectors. aution: Rexnord does not recommend altering or rebuilding standard press-fit chains, or sub-assemblies especially the removal of press-fit components and their replacement with others.

115 Maintenance Information Maintenance Information rive hains he following suggestions are practical methods of increasing chain and sprocket life. he more of them that are followed, the longer the chain and sprocket life will be. Lubrication Lubrication is essential for maximum chain and sprocket life. rive chains can and should be lubricated. Lubrication effectiveness will vary with the amount of lubricant used and frequency of application. Ideally, a lubricant film should constantly be maintained between working parts. hain Operation If possible, manually lubricate the chain once a week when the chain is not under load. It is important to get the lubrication between the pin and the bushing and between the roller and the bushing. he chain is under the least load after it exits from the driver sprocket. his area will contain a catenary sag and this is the area to which manual lubrication should be applied. Pour or brush on a copious amount of oil in a continuous manner. llow the chain to travel two complete cycles. Sprockets Worn or improperly designed sprockets are one of the main causes for premature chain life or chain failure. ere are a few hints on how to get the most out of sprockets. New Sprockets 1. When receiving new sprockets check to see if the sprockets are in pitch by wrapping the chain around sprocket and coupling. 2. Make a Painted Pattern by holding a piece of wood behind the new sprocket tooth and spray paint the tooth outline onto the wood. s the sprocket wears, a check on what the original shape was and how much wear has taken place can be made by putting the painted pattern behind the tooth. ooth Wear On single direction drives only one side of the tooth wears. Reverse the sprocket on the shaft and put the unworn tooth face to work. hain and Sprocket Interaction losely inspect the chain and sprocket interaction to insure a smooth and noiseless operation. he chain should easily enter and exit the sprocket without a hitch. hain longation Wear on the pin outside diameter and bushing inside diameter causes chain elongation. Once the chain has elongated or worn past acceptable limits, jumping of sprocket teeth and/or improper chain-sprocket interaction can be expected. ypical allowable elongations are 3 to 5% of chain pitch for drive chains. fter the chain has been elongated or worn past acceptable limits, it should be replaced. Manual Lubrication Oil ath Lubrication hains operating at relatively high speeds should be completely enclosed in an oil case. he lower strand of the chain should just dip into the oil when the chain is running. Maintain the proper oil level. xcess oil causes churning and heat. ype of Lubricant Oil is recommended as a lubricant using the highest viscosity that will flow at the prevailing temperature: emperature () Lubricant elow S S 40 bove S 50 ow to imensionally Identify hain: irst check chain for any markings. 1. etermine if sidebars have straight or offset construction. 2.

116 Maintenance Information onveyor hains Wherever possible, lubrication of chain is always recommended to assure maximum chain life and optimum conveyor operation. he reduction in friction and increase in wear life usually justifies the additional cost. Under normal conditions, chains with rollers are selected only when proper lubrication is possible. In some applications the presence of a lubricant cannot be tolerated, but it still may be possible to attain satisfactory service with sacrifice to chain and conveyor life. he following are general guides: ype of Lubricant Oil is recommended as a lubricant. Use the same lubricants recommended for drive chains at the same temperature ranges. Grease can be used if it is applied internally into the joint with lubrication fittings on rivets or bushings. Method of Lubrication Oil flow or brush type lubrication is adequate under relatively clean conditions, but they are ineffective with dirty conditions. lush lubrication (flooding the chain) once per day is normally adequate in dirty environments. USING PIN ROLLR ROLLR LINK PLS PIN LINK PLS NOZZL When manually lubricating, the oil should be directed between adjacent outer and inner sidebars (for the joint) and between inner sidebar and roller face (for rollerbushing lubrication). or best results, clean chain and sprocket periodically. he effectiveness of any lubrication method will vary with the amount of lubricant used and the frequency of application. Ideally, a lubricant film should be maintained between working parts. hain and Sprocket Storage o not store in an open area where dust, dirt and water are present. Sprockets, especially the tooth face and the inside of the bore, should be painted with a heavy lubricant to prevent corrosion. Most manufacturers pre-lubricate chain when it is shipped from the manufacturing plant. If you do not intend to use the chain when you receive it and it will be stored for a period of time, the chain should be lubricated periodically. If possible, store chain in a fifty gallon drum or other container filled with Used rain Oil. his will provide excellent protection for the chain as well as good break-in lubrication for the chain when it is finally used. his pre-lubrication will allow the chain and sprockets to break in or shine-up properly. If a chain is installed into the application completely dry this will reduce its overall life. If it is impossible to store in lubricated environment, then oil the chain after installation but before any load is applied. Run the chain for 24 hours without any load to allow for good break-in. It is also a good idea to lubricate drag chain conveyor ways with moly-disulfide so that a proper surface will develop between the chain ways and the chain. hain Installation o not grind the chain pins or the holes in the sidebar in order to assemble the chain. hain reliability is based upon a good press fit of the pins into the sidebars. If you reduce that press fit you can reduce chain life. Lubricate the pin when installing it, as this eases assembly. hains on Idle quipment If the equipment is to be idle for any length of time, clean the chain and sprockets by brushing or swabbing if possible, or with a steam hose. hen cover the chain and sprockets with a light oil. hain Operation If possible, manually lubricate the chain once a week when the chain is not under load. ry to flow the oil between the pin and bushing and between the roller and the bushing. Usually the chain is under the least load after it exits from the driver sprocket. his area should contain a catenary sag, and this is the area where manual lubrication should be applied. low or brush on a predetermined amount of oil in the shortest amount of time possible, but still allowing the chain to travel two complete cycles.

122 ngineering ata atenary Sag he return strand of a chain normally has some slack. his slack results in a sag, called catenary sag, of the chain. his sag must be of the correct amount if the chain is to operate properly. If the return strand is too tight (too little catenary sag), the load and the wear on working parts will be excessive. If the return strand is too loose, vibration and unwanted chain flexure will result. chain that is properly installed will permit flexing of the return strand by hand. his flexure, measured from a straight line, should not be less than about 3% of the horizontal center distance. he amount of catenary sag that will be present can be calculated as follows: S =.375 Where: S = atenary sag (inches) L = Return strand length (inches) = enter distance (inches) = xcess chain, L (inches) epending on the combination of chain pitch, sprocket center distance, and number of teeth in the sprockets, there will always be excess chain in the system. he catenary sag resulting from this excess chain for various sprocket center distances is given in the table below.
