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.
Claims7
An apparatus for testing parts for the transmission and absorption of power, comprising:
- a drive motor;
- a part to be tested having an input drivingly coupled to the drive motor and having an output;
- and
- torque generating means for applying a torque to the part to be tested, the torque generating means having an input member drivingly coupled to the output of the part to be tested and having an output member drivingly coupled to the drive motor, the input member being rotatable through more than 360 degrees relative to the output member, the torque generating means comprising a rotatable hydraulic motor.
