S-Flex Coupling Assortment Process
The variety method for identifying the proper S-Flex coupling calls for working with the charts shown around the following pages. There are 3 elements for being chosen, two flanges and a single sleeve.
Details needed ahead of a coupling is usually chosen:
HP and RPM of Driver or operating torque
Shaft dimension of Driver and Driven tools and corresponding keyways
Application or tools description
Environmental situations (i.e. excessive temperature, corrosive problems, space limitations)
Steps In Deciding on An S-Flex Coupling
Stage one: Ascertain the Nominal Torque in in-lb of one’s application through the use of the following formula:
Nominal Torque = (HP x 63025)/RPM
Step two: Working with the Application Services Element Chart one select the services component which very best corresponds for your application.
Stage three: Determine the Layout Torque of one’s application by multiplying the Nominal Torque calculated in Stage one through the Application Service Component determined in Step 2.
Design and style Torque = Nominal Torque x Application Support Issue
Step 4: Making use of the Sleeve Effectiveness Data Chart 2 choose the sleeve materials which best corresponds to your application.
Stage 5: Using the S-Flex Nominal Rated Torque Chart three find the ideal sleeve material column to the sleeve chosen in Phase 4.
Phase six: Scan down this column to your to start with entry wherever the Torque Worth within the column is better than or equal for the Design Torque calculated in Step three.
Refer towards the maximum RPM worth of the coupling size to guarantee the application necessities are met. In the event the maximum RPM value is significantly less compared to the application necessity, S-Flex couplings are usually not advisable to the application.
Note:
If Nominal Torque is less than 1/4 of the coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. The moment torque value is located, refer for the corresponding coupling dimension inside the 1st column on the S-Flex Nominal Rated Torque Information Chart three .
Step 7: Examine the application driver/driven shaft sizes on the greatest bore dimension obtainable about the coupling selected. If coupling max bore just isn’t substantial adequate for your shaft diameter, select the next largest coupling which will accommodate the driver/driven shaft diameters.
Step 8: Applying the Item Selection tables, uncover the ideal Keyway and Bore dimension required and locate the quantity.
