S-Flex Coupling Assortment Procedure
The assortment system for determining the correct S-Flex coupling involves using the charts proven about the following pages. There are three elements to get chosen, two flanges and one particular sleeve.
Facts important prior to a coupling is often picked:
HP and RPM of Driver or working torque
Shaft size of Driver and Driven equipment and corresponding keyways
Application or tools description
Environmental conditions (i.e. intense temperature, corrosive situations, space limitations)
Measures In Picking out An S-Flex Coupling
Step one: Figure out 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 Element Chart one pick the services factor which very best corresponds to your application.
Step 3: Determine the Style and design Torque of your application by multiplying the Nominal Torque calculated in Stage one through the Application Service Aspect determined in Step two.
Style and design Torque = Nominal Torque x Application Support Element
Step 4: Employing the Sleeve Performance Data Chart 2 choose the sleeve material which very best corresponds for your application.
Phase 5: Employing the S-Flex Nominal Rated Torque Chart three locate the acceptable sleeve material column to the sleeve selected in Stage 4.
Step 6: Scan down this column for the initial entry the place the Torque Value while in the column is higher than or equal for the Style and design Torque calculated in Step 3.
Refer for the highest RPM worth from the coupling size to be sure the application needs are met. In the event the greatest RPM value is significantly less than the application requirement, S-Flex couplings aren’t suggested for your application.
Note:
If Nominal Torque is less than 1/4 from the coupling’s nominalrated torque, misalignment capacities are decreased by 1/2. After torque value is located, refer for the corresponding coupling size inside the initial column with the S-Flex Nominal Rated Torque Data Chart three .
Phase 7: Evaluate the application driver/driven shaft sizes on the optimum bore size offered to the coupling chosen. If coupling max bore just isn’t large enough to the shaft diameter, decide on the next biggest coupling that should accommodate the driver/driven shaft diameters.
Stage 8: Making use of the Item Variety tables, locate the suitable Keyway and Bore size essential and find the variety.
