Method
S-Flex Coupling Selection Process
The variety method for identifying the right S-Flex coupling needs working with the charts proven about the following pages. You can find three elements to get selected, two flanges and 1 sleeve.
Information and facts essential in advance of a coupling may be chosen:
HP and RPM of Driver or working torque
Shaft dimension of Driver and Driven tools and corresponding keyways
Application or gear description
Environmental ailments (i.e. excessive temperature, corrosive circumstances, room limitations)
Steps In Choosing An S-Flex Coupling
Step 1: Ascertain the Nominal Torque in in-lb of the application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Step 2: Working with the Application Services Component Chart 1 decide on the service element which ideal corresponds to your application.
Phase three: Determine the Style and design Torque of the application by multiplying the Nominal Torque calculated in Stage one from the Application Service Issue determined in Phase two.
Style and design Torque = Nominal Torque x Application Support Aspect
Phase 4: Using the Sleeve Effectiveness Information Chart 2 decide on the sleeve materials which best corresponds to your application.
Phase five: Working with the S-Flex Nominal Rated Torque Chart 3 find the suitable sleeve materials column for that sleeve chosen in Phase four.
Phase 6: Scan down this column to your to start with entry the place the Torque Value in the column is higher than or equal to your Design and style Torque calculated in Stage 3.
Refer on the highest RPM value in the coupling size to be sure the application necessities are met. When the highest RPM worth is much less compared to the application necessity, S-Flex couplings usually are not recommended for the application.
Note:
If Nominal Torque is less than 1/4 from the coupling’s nominalrated torque, misalignment capacities are decreased by 1/2. The moment torque worth is found, refer for the corresponding coupling dimension from the first column from the S-Flex Nominal Rated Torque Data Chart 3 .
Stage seven: Assess the application driver/driven shaft sizes towards the maximum bore size obtainable on the coupling selected. If coupling max bore just isn’t massive ample for your shaft diameter, select the subsequent largest coupling that could accommodate the driver/driven shaft diameters.
Phase 8: Applying the Item Selection tables, obtain the appropriate Keyway and Bore dimension required and locate the number.
