Jaw Coupling Choice Procedure

Jaw Type Coupling Assortment Course of action
The variety system for identifying the correct jaw coupling dimension and elastomer demands making use of the charts shown within the following pages. You can find 3 components to become chosen, two hubs and a single elastomer. Once the shaft size in the driver and driven with the application are from the identical diameter, the hubs chosen will probably be the exact same. When shaft diameters Jaw%20couplingsdiffer, hubs selected will vary accordingly.
Information important ahead of a coupling is often chosen:
HP (or KW) and RPM or Torque of driver
Shaft sizes of driver and driven tools and corresponding keyways
Application description
Environmental problems (i.e. excessive temperature, corrosive conditions, space limitations)
Ways In Choosing A Jaw Coupling
Phase one: Figure out the Nominal Torque of the application through the use of the following formula:
Nominal Torque = in-lb = (HP x 63025)/RPM
Nm = (KW x 9550)/RPM
Phase two: Utilizing the Application Services Components Chart 1 decide on the services factor which ideal corresponds to your application.
Step three: Calculate the Layout Torque of the application by multiplying the Nominal Torque calculated in Step one by the Application Support Aspect determined in Stage 2.
Design and style Torque = Nominal Torque x Application Services Aspect
Stage four: Using the Spider Efficiency Data Chart 2, pick the elastomer materials which most effective corresponds to your application.
Stage 5: Making use of the Jaw Nominal Rated Torque Chart three , find the proper elastomer material column for your elastomer chosen in Step 4.
Scan down this column to your to start with entry where the Torque Worth during the ideal column is greater than or equal towards the Style Torque calculated in Step three.
The moment this worth is found, refer to the corresponding coupling size while in the initial column from the Jaw Nominal Rated Torque Chart three .
Refer for the maximum RPM value for this elastomer torque capability to guarantee the application needs are met. In case the necessity just isn’t pleased at this point, a different type of coupling could possibly be required for your application. Please seek the advice of Lovejoy engineering for help.
Step six: Evaluate the application driver/driven shaft sizes on the highest bore dimension out there around the coupling chosen. If coupling bore dimension is just not significant sufficient for the shaft diameter, decide on the subsequent biggest coupling that may accommodate the driver/driven shaft diameters.
Phase 7: Applying the UPC quantity choice table , locate the suitable Bore and Keyway sizes necessary and locate the quantity.
