S-Flex Coupling Variety Process
The choice course of action for figuring out the right S-Flex coupling demands using the charts proven to the following pages. You will find 3 parts to get picked, two flanges and 1 sleeve.
Data needed just before a coupling might be selected:
HP and RPM of Driver or running torque
Shaft size of Driver and Driven products and corresponding keyways
Application or equipment description
Environmental conditions (i.e. intense temperature, corrosive problems, area limitations)
Measures In Picking out An S-Flex Coupling
Step 1: Ascertain the Nominal Torque in in-lb of one’s application by utilizing the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase 2: Making use of the Application Support Issue Chart 1 pick the service factor which ideal corresponds for your application.
Step three: Determine the Design and style Torque of the application by multiplying the Nominal Torque calculated in Stage one from the Application Services Element established in Stage two.
Design and style Torque = Nominal Torque x Application Support Component
Phase 4: Making use of the Sleeve Functionality Information Chart two select the sleeve material which greatest corresponds for your application.
Phase five: Working with the S-Flex Nominal Rated Torque Chart 3 locate the appropriate sleeve materials column to the sleeve chosen in Stage four.
Stage 6: Scan down this column on the to start with entry in which the Torque Value from the column is higher than or equal on the Design and style Torque calculated in Phase 3.
Refer to the maximum RPM worth in the coupling dimension to be sure the application necessities are met. Should the highest RPM worth is much less than the application necessity, S-Flex couplings are not suggested for that application.
If Nominal Torque is less than 1/4 of your coupling’s nominalrated torque, misalignment capacities are decreased by 1/2. After torque worth is found, refer on the corresponding coupling size during the initially column from the S-Flex Nominal Rated Torque Information Chart 3 .
Step 7: Evaluate the application driver/driven shaft sizes on the highest bore size available within the coupling picked. If coupling max bore just isn’t large sufficient for that shaft diameter, select the following biggest coupling that can accommodate the driver/driven shaft diameters.
Phase eight: Applying the Item Assortment tables, obtain the acceptable Keyway and Bore dimension expected and locate the variety.
