ETP-EXPRESS DESIGN OPERATION FEATURES

Transcription

1 ETP-EXPRESS ETP-EXPRESS has just one screw for pressurizing. It is esigne for fast an accurate repositioning of the hub. Since the screw is tightene only in the raial irection, no space is use along the shaft for mounting tools. Other components can be mounte on the shaft all the way up to the flange. 6 ESIGN ETP-EXPRESS consists of a ouble-walle harene steel sleeve an flange fille with a pressure meium. The flange component has a screw an piston with seals to maintain pressure. When the pressure screw is tightene, the oublewalle sleeve expans uniformly against shaft an hub an creates a rigi joint. ismantling is one by loosening the screw which returns the ETP- EXPRESS to its original imensions. It can then easily be ismantle. Fast an frequent mounting/ismantling with only one screw. Raial screw positioning saves space along the shaft. Accurate positioning. No axial movement when mounting. Uniform surface pressure against shaft an hub prevents amage to surfaces an enables the use of small iameter hubs. Hanles temperature range -22 F to 180 F. When the pressure screw is tightene to the recoene tightening torque, the piston has reache the bottom of the bore. ETP-EXPRESS creates a uniform surface pressure against the shaft an hub.

3 Selection On New Applications: 1. Calculate the require torque transmission rating 2. Select the ETP Connection with the proper torque rating 3. Check suitability of shaft an hub 4. Check operating temperature On Existing Applications: 1. Select the ETP Connection for the require shaft size 2. Check the require torque transmission rating 3. Check operating temperature 4. Check existing shaft an hub for a keyway Torque Calculations: Given the horsepower rating of the prime mover an the shaft rpm, the torque transmitte is: Calculating the Require Tr The require torque transmission rating Tr is equal to the calculate torque multiplie by service factor a which will account for high starting torques, transient overloas, shock loas, pulsating loas an alternating loas. Certain types of electric motors have starting torques as high as 2 to 2.5 times rate torque which must be taken into consieration when selecting the ETP. Recoene service factors for various types of applications are shown in the following table: Service Factors Example: A piston engine powere compressor (a = 3) with a torque of 100 lb. ft. will require an ETP with a torque rating of 300 lb. ft. The formula is: Torque (lb-in) = x H.P. rpm Torque (lb-ft) = 5252 x H.P. rpm river Electric Motor Internal Combustion Engine. Type oa Constant Pulsating Alternating Constant Pulsating Alternating Fans Rotary Pumps Generators Centrifuges Chain rives Reciprocating Compressors Piston Pumps Conveyors (belt) Crushers Rolling Mills Tr = Tc x a Tr = torque rating of ETP Tc = calculating torque a = service factor Installation The ETP Connection positions quickly an precisely. Simply slie bushing an hub onto shaft, tighten the clamping screws an the bushing is locke into position. To reposition the ETP Connection on the shaft, loosen screws, move the bushing to its new location an retighten screws. A stanar torque wrench is the only tool you nee to install the ETP Connection. When mounting ETP Connections over an existing keyway, the keyway must be fille in. Shaft an Hub Tolerances ETP CASSIC (inch series) tolerances: ETP CASSIC (metric series) tolerances: Shaft h8 to k6 (ETP-15 only h7) ETP CASSIC R tolerances: Shaft h9 (R-15 only h8) ETP EXPRESS an ETP EXPRESS R tolerances: Shaft h7 for = 15. Shaft h8 for = 5/8", 3/4", 20, 7/8", 25, 1", 1 1/8", 30, 1 3/16",1 1/4", 1 3/8", 35, 1 1/2", 40, 45, 50, 2", 60, 70, 80. Shaft k6-h7 for = 19, 22, 24, 28, 32, 38, 42, 48, 55. ETP TECHNO tolerances: Shaft h8. POSI-OK-K tolerances: Shaft h8. Sizes Shaft Bore 3/4" 7/8"-1 1/2" 1 5/8"-1 15/16" 2"-4" Note: If the ETP Connection is use in an application where tolerances lie outsie the recoene range, torque transmission (Tr) will be reuce. The torque values in the table of sizes are base on these tolerances. 12

4 Stress in Hub an Shaft The stress o is a function of surface pressure an material thickness. At constant surface pressure, o increases with iminishing material thickness. This applies both to hubs an hollow shafts. The table below shows recoene O/I ratios for hubs mae of ifferent materials. Visit the Zero-Max website for aitional technical information at Material O/I Steel (high grae) 1.4 Steel (normal grae) 1.5 Cast Iron 2.0 Aluminum 2.5 O = outsie iameter of hub I = insie iameter of hub These O to I ratios allow for increase surface pressure at elevate working temperature.

There is a limit when screws wear an require replacement. If ETP threas are cleane an regularly lubricate, the guie values in the chart above can be use. Sizing software for ETP Bushings Zero-Max provies free software on a C ROM to help select an size the correct ETP bushing. This C ROM contains all Zero-Max prouct catalogs in a PF format, a comprehensive sizing an selection program an CA rawings for most of the Zero-Max proucts. The sizing an selection portion of the software walks the user through the selection of any Zero-Max prouct an gives a recoenation on which moel to use. The software is very user frienly an can be use on any Winows or Macintosh base computer. 13

5 ETP-KN (Knife Holer) ESIGN The ETP-KN Knife Holer has a similar esign as the ETP Techno except expansion is against the shaft only. It mounts an positions quickly an provies excellent runout an repeatability, for circular knives in slitting applications. The unique pressure chamber esign of ETP-KN sets the knife accurately as the single pressure screw is tightene. ETP-KN is ieal for paper, plastic an metal slitting applications. Repeatable axial run-out of approximately inch. Extremely short length. Very fast to mount, position an remove. Single pressure screw with low tightening torque. Custom esigne for your application, contact Zero-Max. ETP-IMPRESS ESIGN The ETP Impress is a hyraulic mechanical shrink connection. Mounting is one quickly an easily using hyraulic pressure. Then axial locking screws are tightene. Hyraulic pressure is then release an the flanges stay in position hel by the locking screws. ETP Impress hanles up to 190,000 ft. lbs. of transmittable torque. It s ieal for applications requiring high raial force to compress conical rings an hollow shafts. irect relationship between hyraulic pressure an transmittable torque. Prouces uniform surface pressure over hollow an soli shafts. Mounts quickly an accurately in tight places. The Impress connection can be loosene without hyraulic pressure. Can be mounte/ismantle many times without servicing. ETP-HYOC ESIGN The ETP Hyloc is a hyromechanical connection esigne for very heavy uty applications an hostile operating environments. ouble-walle sleeve encloses a conical moveable piston. Three flange-mounte threae connections provie raial or axial hose connection. Mounts quickly, has excellent concentricity an hanles high raial loas. Available in bore sizes from 50 to 220 with transmittable torque to 200,000 ft. lbs. Mounting an ismantling is one with a hyraulic pump. 14

6 The use of the ETP-KN maintains a very tight axial alignment of the knife-ege an maximizes axial runout in the manufacture of three-piece cans. Allows for easy ajustment when changing can sizes or performing machine maintenance. Axial ocking Screw Mounting: Apply pressure in the ON an P (not shown) connections. When mounte no hyraulic pressure remains. The small conical angle prevents the piston from releasing. ismantling: Apply pressure in the OFF an P (not shown) connections. ETP-HYOC returns to its original measurements an the joint is loose. 15
