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 adopting a dislocation tile sliding bearing to support comprises a transmission shaft. The transmission shaft is supported on a dislocation tile sliding bearing. The dislocation tile sliding bearing is fixed to a box body. The box body is fixed to a rack. The rack is equipped with axial and radial loading devices so as to realize loading to a test bearing. A bearing capability of the dislocation tile sliding bearing is good, stability is high and a noise is low. The machine has the advantages that operation is stable; the noise is low and a bearing capability is good. A problem that a support bearing is damaged before the test bearing is damaged in a rolling bearing testing machine is solved and a service life of the testing machine is greatly prolonged.
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 ...
