Repair Of Radial Spherical Plain Bearings

1. Bearing maintenance: In order to maintain the original performance of the bearing in a good condition for as long as possible, maintenance, overhaul, and accident prevention are required to ensure the reliability of operation and improve productivity and economy.

Maintenance is best carried out on a regular basis in accordance with the operating standards for the mechanical operating conditions. The content includes monitoring of operating conditions, replenishment or replacement of lubricants, and periodic disassembly inspections. The maintenance items in operation include the rotation sound of one-way bearing, vibration, temperature, and the state of the lubricant.

2. Repair of Radial spherical plain bearings: Cleaning of the bearing: When disassembling the bearing for repair, first record the appearance of the bearing, confirm the residual amount of the lubricant, and wash the bearing after sampling the lubricant for inspection. As a cleaning agent, gasoline and kerosene are commonly used.

The cleaning of the removed bearings is divided into coarse cleaning and fine cleaning. They are placed in the container respectively, and the metal mesh bottom is placed first so that the bearing does not directly contact the container. In rough cleaning, if the bearing is rotated with dirt, it will damage the rolling surface of the bearing and should be noted. In the rough cleaning oil, use a brush to remove the grease and the adhesive. After it is almost clean, it is transferred to the fine wash.

In the fine washing, the Radial spherical plain bearings are rotated while cleaning, while carefully cleaning. In addition, the cleaning oil should always be kept clean.

3, Radial spherical plain bearings maintenance and judgment: In order to judge whether the removed bearing can be used, it should be checked after Radial spherical plain bearings are washed. Check the condition of the raceway surface, the rolling surface, the mating surface, the wear of the cage, the increase of the one-way bearing clearance, and the damage and abnormality that are irrelevant to the dimensional accuracy. For non-separable miniature ball bearings, use one hand to support the inner ring horizontally and rotate the outer ring to check if it is smooth.
