S-Flex Coupling Selection Process
The choice system for figuring out the correct S-Flex coupling needs employing the charts proven over the following pages. You’ll find three elements to get picked, two flanges and one sleeve.
Data vital prior to a coupling might be chosen:
HP and RPM of Driver or operating torque
Shaft dimension of Driver and Driven equipment and corresponding keyways
Application or equipment description
Environmental conditions (i.e. extreme temperature, corrosive disorders, room limitations)
Ways In Picking An S-Flex Coupling
Phase one: Determine the Nominal Torque in in-lb of your application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Step 2: Working with the Application Services Aspect Chart one select the services component which best corresponds to your application.
Stage three: Calculate the Style and design Torque of the application by multiplying the Nominal Torque calculated in Step one from the Application Service Component determined in Phase two.
Design and style Torque = Nominal Torque x Application Support Factor
Step 4: Making use of the Sleeve Functionality Data Chart two pick the sleeve material which finest corresponds to your application.
Step five: Making use of the S-Flex Nominal Rated Torque Chart three locate the ideal sleeve materials column to the sleeve selected in Stage four.
Phase six: Scan down this column towards the very first entry in which the Torque Value while in the column is better than or equal to the Style Torque calculated in Phase 3.
Refer to the optimum RPM value in the coupling size to guarantee that the application prerequisites are met. In case the optimum RPM value is significantly less than the application requirement, S-Flex couplings will not be advisable for your application.
Note:
If Nominal Torque is much less than 1/4 of the coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. When torque worth is found, refer for the corresponding coupling dimension inside the to start with column from the S-Flex Nominal Rated Torque Information Chart 3 .
Stage 7: Assess the application driver/driven shaft sizes towards the greatest bore dimension readily available over the coupling picked. If coupling max bore is not really big adequate to the shaft diameter, decide on the subsequent biggest coupling which will accommodate the driver/driven shaft diameters.
Phase eight: Employing the Item Variety tables, find the appropriate Keyway and Bore dimension essential and find the amount.
