S-Flex Coupling Assortment Course of action
The choice process for figuring out the correct S-Flex coupling demands making use of the charts proven around the following pages. You will find three components for being picked, two flanges and one particular sleeve.
Data vital just before a coupling is usually selected:
HP and RPM of Driver or operating torque
Shaft size of Driver and Driven gear and corresponding keyways
Application or equipment description
Environmental problems (i.e. intense temperature, corrosive disorders, area limitations)
Techniques In Picking out An S-Flex Coupling
Phase 1: Decide the Nominal Torque in in-lb of one’s application through the use of the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase 2: Making use of the Application Service Issue Chart one pick the support factor which very best corresponds to your application.
Stage three: Determine the Design and style Torque of one’s application by multiplying the Nominal Torque calculated in Stage 1 from the Application Support Element determined in Stage two.
Layout Torque = Nominal Torque x Application Services Component
Stage 4: Working with the Sleeve Functionality Data Chart two pick the sleeve material which finest corresponds for your application.
Stage five: Making use of the S-Flex Nominal Rated Torque Chart 3 find the appropriate sleeve material column to the sleeve selected in Stage 4.
Stage six: Scan down this column on the 1st entry in which the Torque Worth from the column is greater than or equal on the Design Torque calculated in Step 3.
Refer towards the optimum RPM worth of the coupling size to make sure the application needs are met. Should the optimum RPM worth is less than the application requirement, S-Flex couplings are not encouraged for that application.
If Nominal Torque is significantly less than 1/4 of your coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. After torque worth is found, refer towards the corresponding coupling dimension inside the initially column of your S-Flex Nominal Rated Torque Information Chart three .
Step seven: Evaluate the application driver/driven shaft sizes to the highest bore dimension accessible to the coupling picked. If coupling max bore is not big adequate for that shaft diameter, pick the following greatest coupling that can accommodate the driver/driven shaft diameters.
Stage eight: Employing the Item Assortment tables, uncover the acceptable Keyway and Bore size expected and find the variety.
