ABSTRACT:
A test apparatus applies torque to rotating parts to be tested. A drive motor rotates a first shaft. A first coupling connects the first shaft with an input of the part to be tested. The second coupling connects an output of the part to be tested with an input member of a torque generating hydraulic motor. An output member of the hydraulic motor is non-rotatably coupled to the first shaft. The input member may rotate through more than 360.degree. relative to the output member. Pressure in the hydraulic motor may be varied to control the amount of torque applied to the parts to be tested.
