Difference between the rolling and sliding bearings, the first appearance of the structure, the rolling bearing is rotating body by rolling to support the rotating shaft, which is a point of contact area, the rolling body more, contact more; sliding bearings rely on a smooth surface to support the rotating shaft, which is a surface contact area. Followed by the movement in different way, the movement pattern is a rolling bearing; sliding bearings is a sliding movement pattern, so the situation on the friction is not the same.
Sliding bearing, working under the sliding friction bearings. Sliding bearing stable, reliable, no noise. In liquid lubrication conditions, separated by sliding surface oil without direct contact, but also can greatly reduce the friction loss and surface abrasion, oil film also has a certain vibration absorption capacity. But the larger starting frictional resistance. Axle bearing portion is called the journal, and the journal match parts known as bush. Antifriction material layer in order to improve the bearing surface friction properties in the surface casting called bearing liner. Bearing and bearing lining materials are collectively known as the sliding bearing materials.
Sliding bearing work, there is a thin layer of oil film lubrication requirements between the bearing and shaft. If due to poor lubrication, there is the direct friction between bearing and shaft, friction will produce very high temperature, while the bearing is due to the special high temperature resistant alloy material, but direct frictional heat is still on the liner burnt. Bush also may be due to overload, high temperature, oil viscosity impurities or abnormal factors such as bush-burning. Sliding bearing is damaged tile.
The so-called scraping bush, is finishing tiles and the assembly axis (axis of research should be coated with toner), with a triangular scraper to remove the attached tiles on the pink, with the research with the blow, until the tile of color area of more than 85% complete full tile surface, scraping. There is a mark of tile tile store lubricating oil storage tank.
