Device for testing idle stroke rotation angle of input shaft end of transmission

The utility model discloses an idle stroke rotation angle testing device for a transmission input shaft end, which is characterized in that a transmission input shaft extends into a spline housing and is fixed through a locking screw, a bidirectional torque wrench is connected to the spline housing and rotates forwards and reversely along the radial direction of the transmission input shaft, and a digital display magnetic type angle gauge is arranged on the spline housing. And the rotation angle of the spline housing is displayed through the digital display magnetic type angle gauge. The device is used for the idle stroke rotation angle test of the input shaft end of the transmission in the transmission production offline, ensures the consistency and accuracy of the test result of the idle stroke rotation angle test, and has the characteristics of simple structure, convenience in operation, higher test efficiency, lower cost, easiness in implementation and the like. 本实用新型公开了一种用于变速器输入轴端空行程转角测试装置，采用变速器输入轴伸入花键套中
