S-Flex Coupling Variety Process
The choice process for identifying the correct S-Flex coupling involves working with the charts shown over the following pages. You will find 3 components for being selected, two flanges and one sleeve.
Information required just before a coupling is usually selected:
HP and RPM of Driver or working torque
Shaft dimension of Driver and Driven tools and corresponding keyways
Application or tools description
Environmental conditions (i.e. intense temperature, corrosive ailments, area limitations)
Techniques In Selecting An S-Flex Coupling
Step one: Establish the Nominal Torque in in-lb of your application through the use of the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase two: Working with the Application Services Element Chart one choose the services factor which best corresponds to your application.
Phase 3: Calculate the Design and style Torque of one’s application by multiplying the Nominal Torque calculated in Stage 1 through the Application Service Factor established in Stage 2.
Style and design Torque = Nominal Torque x Application Services Element
Phase four: Utilizing the Sleeve Efficiency Data Chart 2 pick the sleeve materials which most effective corresponds for your application.
Phase five: Applying the S-Flex Nominal Rated Torque Chart 3 find the suitable sleeve materials column for your sleeve picked in Stage four.
Stage six: Scan down this column to your initially entry where the Torque Value while in the column is better than or equal to your Design Torque calculated in Stage 3.
Refer to your greatest RPM worth with the coupling size to make sure that the application demands are met. In case the highest RPM worth is much less than the application requirement, S-Flex couplings will not be proposed for your application.
If Nominal Torque is much less than 1/4 with the coupling’s nominalrated torque, misalignment capacities are lowered by 1/2. After torque value is found, refer for the corresponding coupling size in the initially column in the S-Flex Nominal Rated Torque Information Chart three .
Stage seven: Review the application driver/driven shaft sizes on the highest bore size obtainable over the coupling selected. If coupling max bore isn’t significant enough for that shaft diameter, choose the following greatest coupling that may accommodate the driver/driven shaft diameters.
Stage 8: Working with the Item Assortment tables, discover the ideal Keyway and Bore size needed and locate the quantity.
