S-Flex Coupling Variety Course of action
The assortment approach for figuring out the correct S-Flex coupling requires employing the charts shown around the following pages. You can find three elements to become chosen, two flanges and one particular sleeve.
Data needed just before a coupling is usually picked:
HP and RPM of Driver or running torque
Shaft dimension of Driver and Driven equipment and corresponding keyways
Application or equipment description
Environmental conditions (i.e. intense temperature, corrosive situations, room limitations)
Steps In Selecting An S-Flex Coupling
Stage one: Decide the Nominal Torque in in-lb of the application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage 2: Making use of the Application Service Factor Chart one decide on the support component which most effective corresponds for your application.
Stage three: Calculate the Design and style Torque of one’s application by multiplying the Nominal Torque calculated in Phase one through the Application Support Aspect established in Stage 2.
Layout Torque = Nominal Torque x Application Support Factor
Phase four: Using the Sleeve Overall performance Information Chart two pick the sleeve material which most effective corresponds to your application.
Stage five: Employing the S-Flex Nominal Rated Torque Chart three find the acceptable sleeve material column to the sleeve picked in Phase 4.
Step six: Scan down this column to your very first entry exactly where the Torque Value inside the column is better than or equal to the Design and style Torque calculated in Step 3.
Refer to your highest RPM value in the coupling dimension to make sure that the application demands are met. In the event the maximum RPM value is less than the application requirement, S-Flex couplings are certainly not proposed for that application.
If Nominal Torque is much less than 1/4 with the coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. Once torque value is located, refer to the corresponding coupling dimension during the initially column in the S-Flex Nominal Rated Torque Data Chart 3 .
Stage 7: Compare the application driver/driven shaft sizes for the optimum bore size accessible to the coupling picked. If coupling max bore isn’t huge adequate for the shaft diameter, pick the next greatest coupling that will accommodate the driver/driven shaft diameters.
Stage 8: Utilizing the Item Selection tables, locate the appropriate Keyway and Bore dimension needed and locate the amount.
