Description

Technical Field

[0001] The utility model relates to the technical field of bearing testing, in particular to a friction testing device for detecting the wear resistance of a bearing surface. Background Art

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. In other words, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during transmission. According to the different friction properties of the moving elements, bearings can be divided into rolling bearings and sliding bearings.

[0003] After the bearing is produced, in order to ensure its performance, it is often necessary to test the wear resistance of the bearing surface, that is, measure the size of the bearing in advance, and then rub the outer surface of the bearing with the corresponding friction block. After a certain period of friction, measure the size of the bearing again, and then test the wear resistance of the bearing. However, it is difficult for the existing friction test device to fix bearings of different models well, resulting in certain limitations in the use of the device; in addition, the friction block will also be worn after long-term use, so it needs to be replaced regularly. In summary, the existing friction test device still has the following problems:
