PURPOSE: A gear testing device is provided to simultaneously measure torque and interlocking force when vibration is caused by gear engagement when an interlocked work gear, which is desired to inspect, is rotated and to utilize the same for a gear process quality test, thereby improving the performance of the gear by accurately testing a noise vibration quality. CONSTITUTION: A gear testing device comprises a driving motor(20), a testing frame(50), a torque loading device(90), an actuator(60), a pressure sensor(70), a vibration measuring device(80), a torque measuring device(30), and a control unit(110). The driving motor rotates a work gear to be quality tested. The testing frame is installed so that the work gear can be rotated while in an engaged state with a master gear. The torque loading device is installed on a rotary shaft of the master gear, thereby applying load torque to the master gear. The pressure sensor measures the driving pressure of the actuator. The vibration measuring device is installed on the testing frame, thereby measuring vibration generated when the work gear engaged with the master gear is rotated. The torque measuring device is installed in the driving motor, thereby measuring a rotating speed and the actuating torque of the driving shaft of the work gear. The control unit compares variations of the pressure signals, torque signals, and vibration measuring signals with a preset reference value by receiving sensing signals of the pressure sensor, vibration measuring device, and the torque measuring device, thereby checking the existence of a failure of the work gear.
