Test gear dismounting device and use method thereof

The invention discloses a test gear dismounting device and a use method thereof. The test gear dismounting device comprises a motor rotating shaft, a motor test gear tightly sleeving the motor rotating shaft, a chuck clamping the motor test gear, a positioning shaft rigidly connected to the end face of the motor rotating shaft, and a power mechanism connected to the positioning shaft. According to the test gear dismounting device and the use method thereof, the problem that in the prior art, if an existing method for expanding the inner surface of the test gear is still adopted, the test gear cannot fall off from the rotating shaft due to leakage is solved. 本发明公开了一种试验齿轮拆卸装置及其使用方法，该装置包括电机转轴、紧密套设于所述电机转轴外的电机试验齿轮、将所述电机试验齿轮夹持的卡盘、刚性连接于所述电机转轴端面的定位轴、连接于所述定位轴的动力机构。本发明解决了现有技术存在的如果依然采用既有的涨大试验齿轮内表面的方法，试验齿轮将因为泄漏问题而无法从转轴上脱落下来等问题。
