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

Embodiment Construction
[0015] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0016] refer to figure 1 , figure 2 , image 3 and Figure 4 , a high-speed rolling bearing dynamic performance testing machine supported by tilting pad bearings, including a frame 1, the frame 1 is connected with a lower box 12, the upper part of the lower box 12 is connected with an upper box 10, and the upper box 10 is connected to the upper box. The upper part is connected with a lifting ring 9 to facilitate lifting when the bearing testing machine is disassembled and assembled. The transmission shaft 11 passes through the inner cavity enclosed by the upper case 10 and the lower case 12. The right end of the transmission shaft 11 is processed with a flange 11b. For connecting the drive unit, a test bearing 32 is installed on the left end of the transmission shaft 11 and is locked by a lock nut 31. The left side of the transmission shaft 11 is su...

A high-speed rolling bearing dynamic performance testing machine supported by a tilting pad bearing, including a drive shaft, the drive shaft is supported on the tilting pad bearing, the tilting pad bearing is fixed on a box body, the box body is fixed on a frame, and the frame Axial and radial loading devices are installed on the test bearing to realize the loading of the test bearing. The tilting pad bearing has extremely high stability and can work for a long time under high-speed conditions. The present invention has the advantages of high rotational speed, stable operation and low noise. More importantly, it solves the problem that the support bearing in the rolling bearing testing machine is damaged before the test bearing, 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 high-speed rolling bearing dynamic performance testing machine supported by a tilting pad bearing. Background technique [0002] The rolling bearing testing machine is a kind of equipment that can truly simulate the actual working conditions such as rolling bearing speed, load, ambient temperature and lubrication state, and test and verify the dynamic performance and life of the bearing. It has 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 all have shortcomings such as small bearing capacity, poor shock load resistance, high noise and short life to varying degrees. In the rolling bearing testing machine, the working condition of the rolling bearing used as the support bearing is often worse t...
