S-Flex Variety

S-Flex Coupling Assortment Course of action
The selection system for identifying the proper S-Flex coupling demands applying the charts proven about the following pages. You’ll find 3 components for being picked, two flanges and 1 sleeve.
Facts needed ahead of a coupling can be picked:
HP and RPM of Driver or working torque
Shaft dimension of Driver and Driven equipment and corresponding keyways
Application or equipment description
Environmental situations (i.e. excessive temperature, corrosive situations, area limitations)
Measures In Deciding on An S-Flex Coupling
Phase one: Decide the Nominal Torque in in-lb of one’s application by utilizing the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase two: Utilizing the Application Services Component Chart 1 pick the services aspect which most effective corresponds to your application.
Step 3: Calculate the Style and design Torque of the application by multiplying the Nominal Torque calculated in Phase one through the Application Support Factor determined in Step 2.
Design and style Torque = Nominal Torque x Application Support Issue
Stage four: Using the Sleeve Efficiency Information Chart 2 choose the sleeve materials which most effective corresponds to your application.
Phase five: Utilizing the S-Flex Nominal Rated Torque Chart three find the appropriate sleeve materials column for the sleeve picked in Phase 4.
Phase 6: Scan down this column to the very first entry exactly where the Torque Worth within the column is better than or equal for the Design and style Torque calculated in Phase three.
Refer towards the highest RPM value on the coupling size to guarantee the application demands are met. When the highest RPM worth is significantly less compared to the application requirement, S-Flex couplings usually are not advised for your application.
If Nominal Torque is much less than 1/4 of your coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. As soon as torque worth is located, refer to the corresponding coupling size inside the very first column from the S-Flex Nominal Rated Torque Information Chart 3 .
Phase seven: Evaluate the application driver/driven shaft sizes towards the highest bore size obtainable about the coupling chosen. If coupling max bore isn’t massive ample for the shaft diameter, pick the subsequent greatest coupling that can accommodate the driver/driven shaft diameters.
Phase 8: Applying the Item Choice tables, come across the suitable Keyway and Bore size necessary and find the quantity.
