[0002] The drive shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial. The drive shaft needs to undergo multiple tests before leaving the factory. Among them, the surface smoothness test is to use a roughness tester to test the smoothness of the drive shaft's flat surface, inclined surface, curved surface, etc.

[0003] When using a roughness tester to test the smoothness of the surface of a drive shaft, the drive shaft is usually placed on a support rod, and then the tester is operated to face the drive shaft. The surface of the drive shaft is tested by manually rotating the drive shaft. This method is labor-intensive and the angle of rotation of the drive shaft cannot be accurately controlled manually, resulting in the inability to ensure a comprehensive test of the surface of the drive shaft, and the test results are prone to errors.
