2 The Ieal ocking evices For Shaft-to-Hub Connections. ETP Connections are ieal for positioning an locking shaft components in a system. They are the best solution where keyways an tapers can weaken or cause excess wear to the shaft components. ETP Connections also aress applications for synchronization of moving parts. They provie precision mounting of shaft components where frequent reajusting is neee, in systems where balance an runout are inherent problems an where coon fastening, ajusting an holing of shaft components are require. There are ETP moels esigne to solve specific requirements such as high transmittable torque an special applications. ETP Classic an Express moels are available in stainless steel for corrosion protection an to hanle frequent washowns. Proven esign. Easy To Use. ETP Connections feature a ouble-walle sleeve an tightening mechanism. They form a soli continuous connection between shaft an hub when tightene. See specific moel information for complete operating instructions. All ETP moels slie onto a shaft easily, an securely lock in position most shaft mounte motion control components. They isassemble equally fast

3 There s A Zero-Max Moel For Every Application ETP Connection Benefits Provie A Soli Connection Between Shaft an Hub Without Stress or Wear to Your Components. Eliminates keyways, tapers an tappe holes which can cause component stress an wear, ue to fretting an backlash. Mount Shaft Components Easier, Faster an More Precisely. All you nee to o is mount, set in position an lock the ETP Connection with a torque wrench. Completely Ajustable. Ajusts raially an axially. Unlike keyways which are non-ajustable, ETP Connections are infinitely phase-ajustable, making them more precise an easier to use. Save Space an Material. Since it is not necessary to mill keyways in the shaft, a smaller shaft can be use, thus saving space an material. Reuce Component Wear an System owntime. May be tightene an repositione without wear an with minimum owntime. ETP Classic Pages 4-5 Provies the highest raial loa. Has flange mounte tightening screws.

12 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.

13 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.

15 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
