Abstract: As an important basic component of mechanical transmission, bearings are extremely important in practical engineering practice and cutting-edge scientific research. With the popularity of automobiles, the development of the related bearing industry has also been greatly promoted. However, the unevenness of the bearing manufacturing industry level directly leads to the difference in bearing quality. In order to be able to sample the bearing samples to a certain extent before the bearings are put on the market, technicians gradually began to develop and produce bearing testing machines. Studies have shown that during the development of bearings, the bearing structure needs to be tested to check the adaptability of the bearing structure to the working environment. Throughout the entire bearing development process, the bearing test is an important part of design, development and manufacturing, and is the basic guarantee for the high quality of the design results.
