When repairing the imported bearing under disassembly, first record the appearance of the bearing, confirm the residual amount of lubricant, and after sampling, clean the imported bearing. Gasoline and kerosene are commonly used as cleaning agents. The cleaning of the removed imported bearings is divided into rough washing and fine washing. The metal mesh is placed in the container so that the bearing does not directly contact the dirt in the container. In rough washing, if the bearing rotates with dirt, it will damage the rolling surface of the imported bearing and should be noted. In the rough wash oil, use a brush to remove the grease and adhesive, and after basically cleaning, transfer to the fine wash. Fine washing is to carefully clean the imported bearings while rotating in the cleaning oil. In addition, the cleaning oil should be replaced frequently to keep it clean. Inspection and judgment of imported bearings When judging whether the imported bearing under disassembly can be used again, it is necessary to check after the bearing is cleaned, and carefully check the condition of the raceway surface, the rolling surface, the mating surface, the wear of the cage, whether the bearing clearance of the imported bearings in Suzhou increases and whether there is any influence on the size. Damage and abnormality with reduced accuracy. For non-separable small ball bearings, use a one-handed flat end inner ring and rotate the outer ring to check if it is smooth. Separate bearings such as tapered roller bearings can be inspected separately for the rolling surfaces of the rolling elements and the outer ring. Large bearings cannot be rotated by hand. Pay attention to the appearance of rolling elements, raceways, cages, ribs, etc. The higher the importance of bearings, the more careful inspection is required. When judging whether the imported bearings can be used again, it should be determined according to the damage degree, mechanical properties, importance, operating conditions, inspection period and other related factors of the bearings imported from Suzhou. However, if the following defects are found during the inspection, the bearing cannot be used any more and the new imported bearing needs to be replaced.
