S-Flex Coupling Variety Procedure
The choice process for figuring out the correct S-Flex coupling necessitates utilizing the charts proven over the following pages. You will discover three components to become picked, two flanges and one particular sleeve.
Information essential before a coupling is often picked:
HP and RPM of Driver or operating torque
Shaft dimension of Driver and Driven equipment and corresponding keyways
Application or products description
Environmental ailments (i.e. intense temperature, corrosive problems, area limitations)
Methods In Deciding on An S-Flex Coupling
Stage 1: Decide the Nominal Torque in in-lb of the application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Step 2: Employing the Application Services Element Chart one select the service issue which greatest corresponds to your application.
Phase 3: Determine the Layout Torque of the application by multiplying the Nominal Torque calculated in Stage one from the Application Service Issue determined in Step two.
Style Torque = Nominal Torque x Application Services Aspect
Stage four: Making use of the Sleeve Functionality Data Chart two decide on the sleeve material which ideal corresponds to your application.
Phase five: Using the S-Flex Nominal Rated Torque Chart 3 find the appropriate sleeve materials column for the sleeve chosen in Stage four.
Step six: Scan down this column to the first entry exactly where the Torque Value from the column is better than or equal to your Style and design Torque calculated in Phase 3.
Refer for the highest RPM value on the coupling size to guarantee the application prerequisites are met. If your maximum RPM worth is much less than the application necessity, S-Flex couplings are certainly not suggested to the application.
If Nominal Torque is significantly less than 1/4 of the coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. After torque worth is located, refer for the corresponding coupling dimension in the very first column of your S-Flex Nominal Rated Torque Data Chart three .
Stage seven: Compare the application driver/driven shaft sizes on the greatest bore dimension available to the coupling selected. If coupling max bore is not really large sufficient for the shaft diameter, choose the subsequent largest coupling which will accommodate the driver/driven shaft diameters.
Step 8: Applying the Item Variety tables, discover the suitable Keyway and Bore dimension required and locate the amount.
