How PM&I Can Help Prevent Delays

Flexible Shaft Couplings

 

Coupling Specifications 

Gearbox Cross List

 
 

1. Selecting the Correct Flexible Coupling: (Details Required to be provided to PMI)

  A: Engine Horse Power and Engine Speed

  B: Gearbox type and Reduction Ratio

  C: Gearbox Flange Details:

    - Diameter of Flange

    - Diameter of the Register

    - Diameter of Pitch Circle (center of 12 o'clock hole to center of 6 o'clock hole)

To receive a quote: email or call with this information.

   

2. Flexible Shaft Coupling Installation:

  A: Roughly align engine and gear without flexible coupling. (i.e. only 2 rigid half couplings pushed together)

  B: Bolt the flexible coupling between the two rigid couplings.

  C: Check alignment (as shown below) of the engine by placing a feeler gauge (purchased inexpensively at most hardware stores) between the bolt head and the rigid half coupling.  Repeat for the SAME BOLT after rotating shaft 90 degrees until gap has been measured 4 times (1 complete rotation of shaft).

  D: If the gap is the same in all four positions, the engine is accurately aligned.  Recommended minimum to maximum gap difference of 0.010 inch / 0.25 mm.

  E: Run engine after installation to bring engine compartment to working temperature.  Re-check torque settings.
