For the maintenance of rolling bearing

For the maintenance of rolling bearing 2021 - 02 - 18 the author: Mr. Wu ( Leiyang power generation company) Rolling bearing is running between the shaft and the shaft seat sliding friction into rolling friction, thereby reducing friction loss of a precision mechanical components. Rolling bearings generally consists of inner ring and outer ring, rolling body and keep the frame of four parts, the function of inner ring is match with shaft and shaft rotation; Outer ring is used to match the bearing seat, a support role; Rolling body is with the aid of maintains a uniform distribution of the rolling element between inner ring and outer ring, its shape size and quantity directly affects the using performance and life of rolling bearing; Maintains a uniform distribution can make the roller, guide roller rotation lubrication. First, remove the note 1. Remove the application of special tools, to avoid direct knock. 2. Must knock, the application of low hardness of metal bar, tapping force shall not be added in the rolling element and keep on the shelf. 3. Avoid damage shaft, bearings and other parts. Two new bearings, bearings cleaning use anti-rust oil sealed bearings can use diesel oil or kerosene cleaning; The old bearings available metal detergent or diesel, kerosene cleaning. Three, bearing inspection and sentenced to waste standard fault common reason: flake peeling, wear, overheating discoloration, rust, crack and breakage, and so on. Check project: raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the bearing clearance and the decrease of the dimension precision of damage, abnormal. Sentenced to waste standard: 1. Inner ring and outer ring, rolling body, cage, ring, any one have crack or gap. 2. Raceway surface, guard, with significant rolling body relaxation indentation and playing. 3. Inner ring diameter or outer diameter surface has obvious creep. （ Source: actively micro class)
