Shaft Coupling

This report discusses attributes of different types of shaft couplings used to transfer power from the engine shaft to the hydraulic pump.

Jaw Coupling

The jaw coupling is composed of three pieces:

• Two coupling halves, to connect to each of the two halves, with three piece jaws to transfer power and a spider insert to make soft connection between the two jaw halves:

Note: Experience has shown that this type of coupling does not work well with the Power Cube, as the spider insert fails after 40 to 100 hours of operation.

Double Roller Chain Coupling

The double roller chain coupling is composed of three pieces:

• Two pieces connecting to each of the two shafts
• A chain to transfer power between the two shaft couplings
