S-Flex Coupling Variety Course of action
The assortment process for determining the right S-Flex coupling calls for using the charts shown to the following pages. There are actually three elements to be picked, two flanges and a single sleeve.
Facts important in advance of a coupling might be chosen:
HP and RPM of Driver or working torque
Shaft size of Driver and Driven tools and corresponding keyways
Application or tools description
Environmental disorders (i.e. severe temperature, corrosive ailments, area limitations)
Steps In Deciding on An S-Flex Coupling
Step 1: Identify the Nominal Torque in in-lb of one’s application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase two: Applying the Application Service Issue Chart one pick the services factor which very best corresponds to your application.
Step 3: Determine the Design and style Torque of the application by multiplying the Nominal Torque calculated in Step one through the Application Services Component established in Stage 2.
Style Torque = Nominal Torque x Application Services Aspect
Stage four: Applying the Sleeve Overall performance Data Chart 2 decide on the sleeve materials which best corresponds to your application.
Step 5: Employing the S-Flex Nominal Rated Torque Chart three find the appropriate sleeve material column for the sleeve selected in Step four.
Phase six: Scan down this column for the to start with entry the place the Torque Worth in the column is greater than or equal to your Design and style Torque calculated in Phase three.
Refer towards the maximum RPM worth in the coupling size to guarantee that the application needs are met. If the maximum RPM worth is much less than the application necessity, S-Flex couplings are certainly not recommended to the application.
If Nominal Torque is less than 1/4 with the coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. As soon as torque value is located, refer to your corresponding coupling size within the initially column of the S-Flex Nominal Rated Torque Information Chart three .
Stage seven: Review the application driver/driven shaft sizes to the highest bore dimension readily available on the coupling picked. If coupling max bore just isn’t substantial enough to the shaft diameter, decide on the subsequent biggest coupling which will accommodate the driver/driven shaft diameters.
Stage 8: Making use of the Item Choice tables, find the appropriate Keyway and Bore size expected and find the variety.
