1. Maintenance of imported bearings
In order to maintain the original Repair Of performance of imported bearings in good condition for as long as possible, they must be maintained and overhauled in order to prevent accidents, ensure the reliability of operation and improve productivity and economy.
Maintain the operation standard of corresponding mechanical Repair Of operation conditions and carry out it regularly. The contents include monitoring the operation status, replenishing or changing the lubricant, and regular disassembly inspection.
As maintenance items in operation, there are rotating Repair Of sound, vibration, temperature, lubricant state of imported bearings, etc.
2. Maintenance of imported bearings
Cleaning of imported bearing: when disassembling the imported bearing for maintenance, first record the appearance of the imported bearing, confirm the residual amount of lubricant, and wash the imported bearing after sampling the lubricant for Repair Of inspection. As a cleaning agent, generally use cleaning agent and kerosene.
They are placed in the container respectively. First, put the metal mesh bottom so that the inlet Repair Of bearing does not directly contact the dirt of the container.
During rough cleaning, if the imported bearing rotates with dirt, it will damage the rolling surface of the imported bearing, which Repair Of should be paid attention to. In the coarse cleaning oil, use a brush to remove the grease and adhesion. After it is roughly clean, turn to fine cleaning.
Fine cleaning is to carefully clean the imported bearing while rotating in the cleaning oil. In addition, the cleaning oil should always be kept clean.
Maintenance and judgment of imported bearing: in order to judge whether the disassembled Repair Of imported bearing can be used, it shall be checked after the imported bearing is cleaned.
Check the state of the raceway surface, rolling surface and mating surface, the wear of the cage, the increase of the clearance of the inlet bearing and the damage of irrelevant dimensional accuracy. For non separable small ball imported bearings, support the inner ring horizontally with one hand and rotate the outer ring to confirm whether it is smooth.
The tapered roller inlet bearing is a separable inlet bearing, and the raceway surface of the rolling Repair Of element and outer ring can be inspected respectively.
Since large imported bearings cannot be rotated by hand, pay attention to the appearance of rolling elements, raceway surfaces, cages, edge retaining surfaces, etc. the higher the importance of imported bearings, the more careful the inspection is.
