In order to meet tight schedules and keep overhead down, you need to select chain that will perform and last even under the most rigorous conditions. Rexnord orporation, manufacturer of Rex and Link-elt chain for over 100 years, is the leader in the engineered chain industry. Our many years of experience provide unique expertise in material selection, heat treatment and design engineering key factors that add up to superior chain strength and extended wear life. Infeed into one of the many heat treat furnaces used to harden chain components. Note the flame curtain used to protect the furnace atmosphere from the outside environment. What to look for when specifying chain: Wear Resistance chain 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 capabilities exceed that of other chain manufacturers. ombine this with the use of choice materials, and it adds up to superior chain that eliminates costly and unexpected downtime. atigue Strength a key factor leading to the durability of our chains is superior fatigue strength. ightly controlled interference fits between the pins and chain sidebars, proper welding and stress relieving, heat treatment and regular testing, and application experience make our chains the number one choice for your particular application. ross-sections of heat treated chain components. he silver surfaces are the result of acid etching and illustrate the deep case depths our chain components have. ustom built induction coils and ancillary equipment have been designed by Rexnord expressly for induction heat treating chain components and sprockets. 2

3 RX N LINK-L ONVYOR N LVOR INS Strong, fatigue resistant chain is a function of the press fit of pins and bushings. he plexiglas models below help to illustrate this benefit. ully machined pins offer dimensional accuracy critical in the manufacture of reliable, strong chain. In an unloaded state, a pin or bushing with a significant press fit will exert compressive stresses around the chain sidebar hole. Low or non-press fit components exert little to none. his photo shows the stress present around a press fit bushing and the lack of compressive stresses around the non- or low-press fit bushings. Rexnord has invested heavily in N controlled machinery for better lot-to-lot component uniformity. Under load, the stress changes drastically around the low press fit hole but very little around the highly press fit hole. Large stress changes reduce the fatigue resistance of chains. or this reason, Rex and Link-elt chains use an optimum amount of interference to provide that protective compressive stress! Pre-lubrication and shrink wrapping: Rexnord takes extra steps at the end of manufacturing to protect your chain. ll chain is pre-lubricated and shrink wrapped. his means less corrosion and less break-in wear. etter for long-term storage too. his photo depicts a fatigue testing machine used by Rexnord to evaluate chain fatigue strengths and guide us in making improvements. 3

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 increase 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 RS856 R857 R859 R Series R956 R958 R984 RN SL RININ RIN ORY INSLL RS 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.

50 RIV INS NINR SL RIV INS RIV INS esigned to give you superior performance, even under the most punishing conditions Rugged, all-steel Rex 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. 50

51 RIV INS Wear life is directly affected by the hardness and case depth of the wearing components Pins hardened by Rexnord s advanced induction hardening process feature extremely hard wear surfaces and deep case depths as shown above. 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. Ideal replacement for gearing, multiple strand roller chain, and belt drives Requires less precision and expense than gearing center distances are more flexible and adjustable. single strand of Rex 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 flamecut 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. RIV INS 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. 51

Our customers know that Rex chains provide superior strength and durability for extended wear life and trouble free service. Rexnord orporation, manufacturers of Rex chain for over 100 years, is the leader in the chain industry. 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. WL SL INS he Rex Welded Steel Story lot goes into a Rex 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 Rex and competitive chains and it is clear, all welded chains are not created equally. What follows is the story of how we make Rex 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 Rex 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 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 through-hardened condition to give the pin excellent toughness. 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 to assure chain toughness and resistance to breakage. his treatment is standard on WX Narrow Mill chains. Other manufacturers of welded chain compromise their design, either sacrificing component hardness or resistance to overloads. Rex Wide Mill heat treated chains (W) come standard with through-hardened rivets, sidebars and barrels. Other manufactures short-change wear life by not hardening the barrels significantly reducing chain wear life. Only Rex Wide Mill chains have through-hardened barrels! 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!

57 RX WL SL INS Maximizing hain Wear Life (ont d.) he Rexnord story continues with a variety of heat treating options to further extend wear life and increase your plant s productivity. he graphic below represents a chain link with Selectively Induction ardened (SI) sidebars. his process can be applied to chain links to greatly improve sliding wear. 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. Rex 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. 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 especially corrosive applications, Rex 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! WL SL INS Maximizing hain Strength key factor leading to the durability of Rex welded steel chains is superior fatigue strength. Rex 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.

61 RX WL SL INS NW! RVRS RRL WI MILL R INS 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 see igure 1. On shorter conveyors, where the chain contacts the sprocket very frequently, 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 see 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? Inspect your current chain and sprockets. If your chain barrels are worn excessively on the outside, where they contact the sprocket, you can reduce that wear by using this chain design.

62 RX WL SL INS VY UY WL SL R INS Rex 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, no loose pins to move around 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 good resistance to shock loads. Square edges on the wing and sidebar of welded drag chain convey more efficiently than rounded cast chain edges. hey also move a deeper bed of material with each revolution of the chain. eat treated and fabricated steel components eliminate the failures that cast chains experience from casting porosity and inclusions.

63 WL SL INS WLIN INSRUIONS 1 Surfaces to be welded should be clean and free of foreign material. It is not necessary to remove the pre-lubricant 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 5 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. Weld edges should indicate complete fusion without overlap or undercut. WL SL INS 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. UION 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. 63

Specific electrode manufacturer recommendations should be closely followed. WL SL INS 10 Preheating 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. Preheating is usually done by use of a neutral flame to heat the parts prior to or after welding. WL L Preheating and postheating may be required see (10). WL L ZON Preheat: Performed to reduce possibility of weld cracking both surface and subsurface.

103 RX ORROSION-RSISN INS Rex Platinum Series hains with Revolutionary Protective oating Rexnord, the world leader in the manufacture of superior quality chains, is proud to introduce a new corrosion-resistant chain. We have taken our precision, dependable and long-lasting carbon steel engineered chain and given it a revolutionary new coating called SZ, which greatly increases the chain s durability in corrosive environments. his exclusive chain coating uses five distinct metals which are plated as both elemental metals and pseudo alloys. he SZ coating significantly increases the life of our standard chain and out-performs the competition s corrosive resistant chains by up to 375% in certain applications. he unique silver SZ coating won t chip, rust or flake, so it is especially well suited for use in outdoor applications, saltwater environments or the food and beverage industry where frequent wash downs occur. SZ is environmentally safe and the plating process takes place here in the US, so there are no delays in fulfilling orders. Sidebars are individually plated, then assembled to assure a continuous and complete coverage of the special process. Since no heat is introduced into the parts, original heat treatments are maintained. You can now have the strength and durability of carbon steel chain with exceptional corrosion resistance.

105 SPROKS SPROK YPS 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. SPROK SYLS ast rm ody his type of sprocket is generally used where larger sizes are required. he use of arms reduces weight, facilitates handling, and is lower in 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 in 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). Longtooth or gapped-tooth 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 SPROKS SMNL SPROKS N RION WLS 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 RION WLS 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 ray Iron rum langed raction Wheel 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. 105

106 SPROKS SPROKS SLION, SPIIION N ORRIN INORMION 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 of standard sprockets is generally based on providing a working face what will accept the maximum possible 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 is 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. 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. RMN 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 Rexnord s 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 all of our segmental sprockets and traction wheels. If you have a very severe sprocket wear problem this may be the answer contact Rexnord to find out if it is available for your particular sprocket type because not all sizes and styles are available. apped 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 side bars 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. 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! 106

Rexnord Selection Services Rexnord application engineers are available to assist in the selection of chains and components. ather 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. Polymeric (non-metallic) chains have unique selection considerations which are covered in the Polymeric section of this catalog. Rex 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 the 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. RIV RIN SLION Rex 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 Rex and Link-elt drive chains since they withstand heavy shock loads and exposed operating conditions. Rexnord s 3100 Series of steel chain is designed to have advantages and features of our other steel chains and to be a replacement for NSI roller chains. Rex and Link-elt drive chains are not designed for attachments. See pages 10 to 49 for chains with attachments. NRL SIN ONSIRIONS 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 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. 134

135 SIN N SLION Sprockets Rex sprockets are designed with full knowledge of the requirements for proper chain-sprocket interaction. or each size and type of sprocket, Rexnord ngineers have selected the proper tooth pressure angle, pitch-line-clearance, bottom diameter and tooth pocket radius for maximum service. abricated steel sprockets are recommended for all chain drives. ast sprockets with hardened teeth are available and may be suitable for slower drives. Largest Keyseated ore he largest keyseated bore next to each chain selection, indicates the largest shaft that can be used with the sprocket hub selected. he sprocket hub will successfully deliver the required P and RPM. he hub specified is not designed to deliver the possible torque which would be allowed by the largest keyseated shaft. n example of the latter would be a line shaft. 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. RIV RRNMNS 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 SIN N SLION ig. 9 ig. 2 ig. 1 ig. 8 ig. 10 ig. 3 ig

If the shaft has already been determined, use the bore size column to select the appropriate hub dimensions. Note: ast sprockets are not recommended for drive application due to the superior wear resistance of fabricated steel sprockets with induction hardened teeth. If a cast sprocket is desired be sure to check availability of the cast pattern as listed beginning on page 113. If the sprocket unit number is not listed, a pattern is not available. he table gives stocked hub dimensions. ast to order sprocket hubs would be sized per page 111. b. riven Sprocket and ub he proper riven sprocket hub can be determined from the following: riven ub orque = Speed Ratio x river ub orque he speed ratio and driver torque were determined in Step 8b and Step 9a. he riven sprocket hub is selected based on the driven hub torque and using the tables on page 111. Referring to the example above, the driver hub was size I and the torque transmitted was 23,000 in-lbs. If the speed ratio were 2 to 1, we would be transmitting 46,000 in.-lbs. and would require a size L hub, (5.25 by 3) or larger. c.

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 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 flexture 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. 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.

Wear Strips and Ways enerally, it is desirable that the chain wear slower than the liner since it is the more critical and expensive part of these two conveyor components. herefore, the most compatible wear strip should be considered after the proper chain has been selected. onveyor way wear for chains rolling is not a critical consideration but cold finished steel is 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, the chain should be slightly harder than a metal liner to protect it and insure that the liner wears 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.

Special Materials or applications requiring special chain capabilities, a wide range of materials and processing treatments have been developed. onsult Rexnord for details.

Of particular concern is abrasive particles embedded in wearstrips and sprockets. hese particles, once embedded, can work like a file to wear away the chain. Rex sprockets are manufactured from super tough urethane. his material was selected because it is harder than most other available non-metallic sprocket materials and resists particle embedding. UMW sprockets are not recommended for any application where dirt or other abrasives are present. Sprockets Rex polymeric chains are designed specifically for applications where corrosion resistance is desired. he current line of polymeric sprockets compliments the product line by offering additional corrosion resistance components. here are, however, situations that require metallic sprockets. If a decision is made to use steel or cast sprockets, it is imperative to carefully inspect the sprocket for any unusual burrs, ridges, or protrusions and remove them before they come in contact with the polymeric chain. Such abrasive components have the capability of severely reducing the expected service life of the chain. lammability Rex polymeric material will burn and support combustion. cetal thermoplastics will burn with a clear flame and little smoke. are should be taken to keep chain and accessories away from heat sources. o not weld around conveyors or machinery without taking care to protect polymeric materials. Ultra-Violet (UV) Resistance xposure to ultra-violet light can degrade polymeric chain materials. Special UV stabilized materials are available for outdoor application in direct sunlight. Wear Strips Metal Wear Strips Metal wear strips are harder than non-metallics and, in addition, can be heat treated or work hardened to increase hardness. hey are, therefore, suited for applications where abrasive particles are present either from the environment or from the products carried. brasive particles are less likely to imbed in metal wear strips. or non-corrosive environments, plain carbon steel, cold finished, is recommended. or corrosive environments, use stainless steel, one quarter temper minimum (25Rc) cold finish. Steel Plain carbon, cold rolled steel is recommended. Surface finish should be RMS. Use heat treatable grades where available and hardened to 25-30Rc. Lubricants used should have rust inhibitors added. Stainless Steel old rolled finish (32-63 RMS) is recommended. n austenitic grade offers the best corrosion resistance. 161 SIN N SLION

162 SIN N SLION SIN N SLION Wear Strips (ont d.) he softer annealed grades of austenitic stainless steel are not recommended. Interaction between the chain material and the soft stainless steel might develop. When this happens, the resulting wear debris consists almost entirely of finely divided stainless steel particles, nearly black in color, similar to molydisulfide or graphite. he wear of the stainless steel might be rapid while the thermoplastic chain by contrast exhibits only slight wear. herefore, one quarter temper minimum austenitic grade stainless is recommended. Martensitic stainless steels can also be use. hey offer excellent wear resistance when heat treated to 25-35R c, but they are not as corrosion resistant as austenitic. luminum Not recommended due to poor wear resistance. Non-Metallic Wear Strips Non-metallic wear strips have a lower coefficient of friction than metals. hey are generally easier to install and remove and provide for quieter operation. Nylatron is the preferred material, especially for dry operation at high load or high speed conditions around corners. Ultra high molecular weight polyethylene is also recommended for all well lubricated applications and some dry applications. cetal Not recommended for use with acetal chains. It is best not to run identical plastics together. Nylatron Nylatron (nylon with molydisulfide filler) is the preferred material for dry applications because of its low wear state and low friction. It is especially suited for dry operation on double flex chain corners. lthough nylatron is more stable in wet applications than most nylons, it will absorb moisture and expand. herefore, room for expansion must be provided and fasteners must allow for movement. Ultra igh Molecular Weight Polyethylene (UMWP) UMW polyethylene (molecular weight of at least 1.0 million) is recommended for both dry and wet applications on straight runs. It is also recommended for all well lubricated corners and non-lubricated corners where chain load and speed are low. It is not recommended for dry operation on corners where the chain load or speed are high. It is also not recommended for operation in environments where particulate matter is present and can embed in the UMW, subsequently wearing the chain. UMWP has a wear rate equivalent to nylon in nonlubricated applications. It is virtually unaffected by moisture and is more resistant to corrosive chemicals than nylon. It is not as rigid as cast nylon and may deflect when subjected to high loads from sideflexing chains. eflon his material has perhaps the lowest coefficient of friction available in a plastic wear strip material. It is soft and tends to flow off the surface and is not practical as a wear strip material except in low load low speed applications. Lubricant Impregnated Wood Suitable for dry applications where self-lubricating properties of the material are best utilized. Not recommended for abrasive conditions where particles may imbed in the surface and wear the chain. antenary Sag Rex polymeric chain conveyors should provide for proper amount of catenary sag to allow proper chain and sprocket interaction. mple space should be provided for the catenary. If chain sag is excessive or increased due to wear, it should be adjusted to the proper amount of sag by removing links. If space does not permit catenary sag, consult Rexnord. Rex polymeric chains should never be run tight. ttempting to operate the chain with too little catenary sag can result in excessively high chain tension, leading to rapid chain wear to chain breakage. or this reason, screw take-ups are not recommended. eneral hain Pull alculations Overhead onveyors hain pull = Moving Load + Lift Load ➁ (MW x f 1 ) + (RxW) S Where: MW = Moving otal Weight lbs: (Weight of all N348 hain, rolleys, Shackle angers, arriers and Product Weight in the entire conveyor.) f 1 = riction actor (see table).

166 MINNN INORMION MINNN INORMION RIV INS 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. Manual Lubrication Oil ath Lubrication 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 hain 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. 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.

167 MINNN INORMION ONVYOR INS 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 roller 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. rease 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. USIN 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 roller-bushing 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 prelubricate 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 fifth 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 if 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, 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.

174 NINRIN 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: 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.
