S-Flex Coupling Variety Procedure
The choice approach for identifying the proper S-Flex coupling needs using the charts proven within the following pages. There are actually 3 elements to be chosen, two flanges and one sleeve.
Information needed before a coupling could be selected:
HP and RPM of Driver or operating torque
Shaft dimension of Driver and Driven products and corresponding keyways
Application or gear description
Environmental disorders (i.e. severe temperature, corrosive problems, room limitations)
Actions In Picking An S-Flex Coupling
Phase one: Identify the Nominal Torque in in-lb of your application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase two: Making use of the Application Support Component Chart 1 decide on the services issue which finest corresponds for your application.
Phase 3: Calculate the Design and style Torque of your application by multiplying the Nominal Torque calculated in Step 1 from the Application Services Issue established in Step 2.
Design Torque = Nominal Torque x Application Support Element
Stage four: Employing the Sleeve Efficiency Information Chart two choose the sleeve materials which very best corresponds to your application.
Phase five: Using the S-Flex Nominal Rated Torque Chart three locate the acceptable sleeve material column for your sleeve picked in Stage four.
Stage six: Scan down this column on the first entry the place the Torque Worth in the column is better than or equal to the Design and style Torque calculated in Phase three.
Refer to your maximum RPM worth on the coupling size to ensure the application prerequisites are met. When the optimum RPM value is significantly less compared to the application necessity, S-Flex couplings are certainly not encouraged for your application.
If Nominal Torque is much less than 1/4 with the coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. When torque worth is found, refer on the corresponding coupling dimension while in the first column on the S-Flex Nominal Rated Torque Data Chart 3 .
Phase seven: Compare the application driver/driven shaft sizes to your highest bore dimension available to the coupling picked. If coupling max bore is just not massive enough for the shaft diameter, choose the subsequent biggest coupling that should accommodate the driver/driven shaft diameters.
Stage eight: Using the Item Assortment tables, come across the acceptable Keyway and Bore dimension demanded and locate the number.
