Process
S-Flex Coupling Variety Procedure
The variety process for identifying the appropriate S-Flex coupling requires utilizing the charts shown to the following pages. You can find 3 elements for being chosen, two flanges and 1 sleeve.
Details necessary just before a coupling may be chosen:
HP and RPM of Driver or operating torque
Shaft dimension of Driver and Driven tools and corresponding keyways
Application or products description
Environmental problems (i.e. extreme temperature, corrosive disorders, room limitations)
Methods In Picking out An S-Flex Coupling
Phase one: Identify the Nominal Torque in in-lb of your application through the use of the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase 2: Utilizing the Application Support Factor Chart 1 pick the service issue which greatest corresponds to your application.
Phase three: Determine the Design and style Torque of the application by multiplying the Nominal Torque calculated in Phase 1 through the Application Service Aspect determined in Stage 2.
Layout Torque = Nominal Torque x Application Service Aspect
Stage four: Making use of the Sleeve Performance Data Chart two select the sleeve material which greatest corresponds to your application.
Phase five: Applying the S-Flex Nominal Rated Torque Chart three locate the acceptable sleeve materials column to the sleeve selected in Stage four.
Phase six: Scan down this column to your initially entry exactly where the Torque Worth inside the column is greater than or equal to your Style and design Torque calculated in Step three.
Refer to your maximum RPM value with the coupling size to be sure the application requirements are met. In the event the optimum RPM worth is much less compared to the application necessity, S-Flex couplings are certainly not suggested for that application.
Note:
If Nominal Torque is significantly less than 1/4 of your coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. Once torque worth is located, refer for the corresponding coupling size within the very first column with the S-Flex Nominal Rated Torque Data Chart three .
Step 7: Review the application driver/driven shaft sizes to your optimum bore size available within the coupling chosen. If coupling max bore will not be huge enough for your shaft diameter, choose the next biggest coupling that could accommodate the driver/driven shaft diameters.
Phase 8: Employing the Item Assortment tables, obtain the appropriate Keyway and Bore size needed and locate the amount.
