S-Flex Coupling Assortment System
The variety course of action for identifying the proper S-Flex coupling requires utilizing the charts shown about the following pages. You will discover 3 elements to be selected, two flanges and 1 sleeve.
Information necessary prior to a coupling might be picked:
HP and RPM of Driver or running torque
Shaft dimension of Driver and Driven tools and corresponding keyways
Application or gear description
Environmental ailments (i.e. severe temperature, corrosive circumstances, room limitations)
Actions In Picking out An S-Flex Coupling
Phase 1: Identify the Nominal Torque in in-lb of your application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage 2: Working with the Application Service Issue Chart one choose the support factor which very best corresponds for your application.
Stage three: Calculate the Design Torque of one’s application by multiplying the Nominal Torque calculated in Stage 1 from the Application Support Component established in Step 2.
Design and style Torque = Nominal Torque x Application Services Element
Step 4: Utilizing the Sleeve Effectiveness Data Chart 2 choose the sleeve material which ideal corresponds to your application.
Phase 5: Using the S-Flex Nominal Rated Torque Chart three locate the suitable sleeve materials column for your sleeve chosen in Phase four.
Step six: Scan down this column to the first entry in which the Torque Worth during the column is higher than or equal to your Design and style Torque calculated in Phase 3.
Refer on the optimum RPM worth in the coupling dimension to make certain the application demands are met. If your greatest RPM worth is less than the application necessity, S-Flex couplings are certainly not encouraged for that application.
If Nominal Torque is much less than 1/4 in the coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. The moment torque worth is found, refer to the corresponding coupling size in the 1st column on the S-Flex Nominal Rated Torque Information Chart three .
Stage 7: Examine the application driver/driven shaft sizes for the greatest bore size obtainable to the coupling chosen. If coupling max bore is just not huge ample for your shaft diameter, select the next biggest coupling that can accommodate the driver/driven shaft diameters.
Phase eight: Making use of the Item Variety tables, obtain the acceptable Keyway and Bore dimension necessary and locate the variety.
