Problems solved by technology
[0003] At present, all rolling bearing testing machines use rolling bearings as supporting components, and the testing machines have disadvantages such as small load capacity, poor impact load resistance, high noise and short life to varying degrees.
In the rolling bearing testing machine, the working conditions of the rolling bearing used as the supporting bearing are often worse than that of the rolling bearing being tested. During use, the supporting bearing is frequently damaged before the test bearing and the test is forced to be interrupted. This has become a rolling bearing Bottleneck problems to be solved urgently in the development of experimental technology

A rolling bearing dynamic performance testing machine supported by dislocation pad sliding bearings, including a transmission shaft, the transmission shaft is supported on the dislocation pad sliding bearings, the dislocation pad sliding bearings are fixed on a box body, the box body is fixed on a frame, and on the frame Axial and radial loading devices are installed to realize the loading of test bearings. The misaligned pad sliding bearing has strong bearing capacity, high stability and low noise. The invention has the advantages of stable operation, low noise and strong bearing capacity, and more importantly The most important thing is to solve the problem that the supporting bearing is damaged before the test bearing in the rolling bearing testing machine, which greatly prolongs the service life of the testing machine.
Description
technical field [0001] The invention relates to the technical field of rolling bearing testing machines, in particular to a rolling bearing dynamic performance testing machine supported by dislocation pad sliding bearings. Background technique [0002] Rolling bearing testing machine is a kind of equipment that can truly simulate the actual working conditions of rolling bearings such as speed, load, ambient temperature and lubrication state, and test and verify the dynamic performance and life of bearings. It plays a very important role in national economy and national defense construction. . [0003] At present, all rolling bearing testing machines use rolling bearings as supporting components, and the testing machines have disadvantages such as small load capacity, poor impact load resistance, high noise and short service life to varying degrees. In the rolling bearing testing machine, the working conditions of the rolling bearing used as the supporting bearing are often ...
