[PDF] Development Of A Power ReCirculating Gear Test

In order to evaluate the performance of gears, a power re-circulating test rig has been designed and developed. The test rig consists of one pair of test spur gears and one pair of helical loading gears. The variation in gear loading is achieved by axial loading of the helical gear using a pneumatic actuator. The no load-starting feature in the test rig reduces the size of the motor.
