S-Flex Coupling Variety Procedure
The selection method for determining the proper S-Flex coupling demands employing the charts shown around the following pages. There are actually 3 elements for being picked, two flanges and 1 sleeve.
Facts required in advance of a coupling may be chosen:
HP and RPM of Driver or running torque
Shaft size of Driver and Driven equipment and corresponding keyways
Application or gear description
Environmental circumstances (i.e. excessive temperature, corrosive situations, area limitations)
Techniques In Deciding on An S-Flex Coupling
Phase 1: Figure out the Nominal Torque in in-lb of the application through the use of \tthe following formula:
Nominal Torque = (HP x 63025)\/RPM
Phase 2: Applying the Application Services Component Chart 1 pick the support factor which most effective corresponds for your application.
Stage 3: Calculate the Design and style Torque of your application by multiplying the Nominal Torque calculated in Step 1 through the Application Service Factor determined in Stage 2.
Style Torque = Nominal Torque x Application Support Aspect
Phase four: Employing the Sleeve Overall performance Information Chart two choose the sleeve materials which finest corresponds to your application.
Stage 5: Applying the S-Flex Nominal Rated Torque Chart three find the appropriate sleeve material column for the sleeve chosen in Step 4.
Phase six: Scan down this column for the very first entry the place the Torque Worth in the column is higher than or equal to your Design Torque calculated in Step 3.
Refer towards the highest RPM worth of the coupling size to make sure that the application prerequisites are met. If the highest RPM worth is less than the application necessity, S-Flex couplings will not be encouraged for that application.
Note:
If Nominal Torque is significantly less than 1\/4 with the coupling\u2019s nominalrated torque, misalignment capacities are lowered by 1\/2. As soon as torque worth is located, refer towards the corresponding coupling size while in the initially column with the S-Flex Nominal Rated Torque Information Chart 3 .
Stage 7: Review the application driver\/driven shaft sizes on the highest bore size offered to the coupling picked. If coupling max bore is not massive ample to the shaft diameter, choose the subsequent largest coupling which will accommodate the driver\/driven shaft diameters.
Phase 8: Working with the Item Choice tables, uncover the appropriate Keyway and Bore dimension expected and
