S-Flex Assortment

S-Flex Coupling Variety Procedure
The selection approach for determining the correct S-Flex coupling demands working with the charts shown over the following pages. You will discover three components for being chosen, two flanges and 1 sleeve.
Data important just before a coupling could be selected:
HP and RPM of Driver or running torque
Shaft dimension of Driver and Driven products and corresponding keyways
Application or equipment description
Environmental problems (i.e. extreme temperature, corrosive problems, space limitations)
Measures In Deciding on An S-Flex Coupling
Stage 1: Figure out the Nominal Torque in in-lb of one’s application by utilizing the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase two: Applying the Application Support Component Chart 1 choose the services component which most effective corresponds to your application.
Stage 3: Determine the Design Torque of the application by multiplying the Nominal Torque calculated in Phase 1 from the Application Service Issue established in Stage two.
Layout Torque = Nominal Torque x Application Services Aspect
Stage 4: Employing the Sleeve Overall performance Information Chart two pick the sleeve materials which best corresponds for your application.
Step five: Working with the S-Flex Nominal Rated Torque Chart three find the acceptable sleeve materials column for that sleeve selected in Phase four.
Stage 6: Scan down this column on the first entry exactly where the Torque Worth within the column is higher than or equal towards the Design and style Torque calculated in Phase three.
Refer on the highest RPM worth of your coupling size to be sure that the application specifications are met. When the optimum RPM worth is significantly less than the application requirement, S-Flex couplings usually are not advisable to the application.
If Nominal Torque is less than 1/4 in the coupling’s nominalrated torque, misalignment capacities are lowered by 1/2. Once torque value is located, refer to the corresponding coupling dimension during the to start with column of your S-Flex Nominal Rated Torque Data Chart three .
Stage seven: Evaluate the application driver/driven shaft sizes for the highest bore dimension out there on the coupling picked. If coupling max bore isn’t massive sufficient for the shaft diameter, decide on the subsequent largest coupling that could accommodate the driver/driven shaft diameters.
Phase 8: Making use of the Item Assortment tables, find the acceptable Keyway and Bore dimension required and locate the quantity.
