AI Technical Summary
Existing drive axle main reducer gear impact testing equipment requires an additional drive unit, has a small test torque range and cannot accurately control the impact load, and lacks a flexible coupling, which means that the test specimen cannot withstand torque load alone.
A drive axle main reducer assembly fixed gear impact test device was designed, including a fixed platform, a test specimen clamping mechanism and a loading assembly. The device uses a loading gearbox, torque meter and flexible coupling to expand the torque range and achieve precise control. The test specimen is fixed and limited by a flange locking device and auxiliary support bracket.
It achieves a wide torque range of loading capacity and precise control of torque load, is suitable for testing various types of drive axle main reducers, is easy to use, and has strong applicability and promotional value.
