Bearing anti-fouling capability testing device

Abstract

The invention relates to a bearing anti-pollution ability testing device, which comprises a base on which a bearing inner frame clamp and a bearing outer frame clamp are rotatably connected; wherein the bearing inner frame clamp includes an upper rotating base, A sliding sleeve is sleeved on the upper rotating base. The sliding sleeve is a cylindrical shell structure with an open top. The rotating base is inserted into the cylindrical shell through the opening end of the sliding sleeve; the side wall of the sliding sleeve corresponds to the closed end position. A bearing compression ring is provided on the outer wall of the bearing compression ring, and an elastic deformation ring A is provided on the outer wall of the bearing compression ring; a limit ring is also provided on the rotating base, and a push ring is also provided on the outer wall of the opening end of the sliding sleeve. The ring and the push ring are elastically connected by a stretching spring; the bearing outer frame clamp includes a lower rotating base, and the lower rotating base includes a lower rotating sleeve, and a rotating disc is slidably connected to the lower rotating sleeve, and the outer periphery of the rotating disc An annular support ring is provided, and an elastic deformation ring B is provided on the inner wall of the support ring.

[0002] For roller bearings, they are often used in some harsh working conditions. The production debris, sediment, impurities, etc. in the environment often have a certain impact on the rotation of the bearing, and the resistance of the bearing Contamination ability is often used as a performance index of bearings, which is closely related to the structure of bearings and the quality of bearing sealing components. Therefore, it is necessary to carry out pollution tests on bearings when manufacturing and finalizing bearings. This not only tests the anti-contamination performance of bearings, but also provides Provide relevant data for the improvement of bearings; while the traditional bearing anti-fouling ability test is generally installed directly in the actual working condition, disassembled after running for a period of time for detection or directly used until scrapped to measure its rotation life, so that the experimental process Longer and more costly, it is impossible to measure and modify the bearing in real time
