Jaw Type Coupling Variety Method
The choice approach for identifying the proper jaw coupling dimension and elastomer demands making use of the charts proven to the following pages. You’ll find three components to become chosen, two hubs and a single elastomer. Once the shaft size from the driver and driven from the application are from the exact same diameter, the hubs picked are going to be the same. When shaft diameters vary, hubs picked will vary accordingly.
Info essential prior to a coupling can be chosen:
HP (or KW) and RPM or Torque of driver
Shaft sizes of driver and driven products and corresponding keyways
Application description
Environmental ailments (i.e. intense temperature, corrosive conditions, space limitations)
Methods In Selecting A Jaw Coupling
Step 1: Decide the Nominal Torque of your application by utilizing the next formula:
Nominal Torque = in-lb = (HP x 63025)/RPM
Nm = (KW x 9550)/RPM
Phase 2: Employing the Application Support Elements Chart one choose the support factor which ideal corresponds to your application.
Step 3: Determine the Style Torque of one’s application by multiplying the Nominal Torque calculated in Stage one through the Application Services Component determined in Stage two.
Layout Torque = Nominal Torque x Application Support Aspect
Step four: Working with the Spider Overall performance Data Chart 2, decide on the elastomer material which finest corresponds to your application.
Step 5: Utilizing the Jaw Nominal Rated Torque Chart 3 , locate the suitable elastomer material column to the elastomer selected in Step four.
Scan down this column towards the very first entry exactly where the Torque Worth within the ideal column is better than or equal for the Style Torque calculated in Stage 3.
As soon as this worth is found, refer for the corresponding coupling size in the first column with the Jaw Nominal Rated Torque Chart three .
Refer to the highest RPM value for this elastomer torque capability to be sure that the application needs are met. In case the requirement just isn’t satisfied at this time, one more variety of coupling can be demanded for that application. Please talk to Lovejoy engineering for assistance.
Stage 6: Review the application driver/driven shaft sizes to your maximum bore dimension accessible to the coupling selected. If coupling bore dimension will not be big sufficient for the shaft diameter, pick the following biggest coupling that may accommodate the driver/driven shaft diameters.
Phase 7: Utilizing the UPC quantity selection table , uncover the suitable Bore and Keyway sizes essential and find the amount.
