After the bearing is installed, check the operation in order to check if the installation is correct. The small machine can be rotated by hand to confirm whether the rotation is smooth. The inspection items have poor operation due to foreign matter, scratches, and indentations. The installation is poor, the torque generated by the mounting is not stable, and the torque is too large due to too small clearance, installation error, and sealing friction. Wait. If there is no abnormality, the power running can be started.
When disassembling the imported bearing for inspection, first record the appearance of the bearing, confirm the residual amount of lubricant, and after sampling the lubricant for inspection, wash the bearing. As a cleaning agent, gasoline and kerosene are commonly used.
The cleaning of the removed imported bearings is divided into coarse cleaning and fine fine washing. In the container, the metal mesh bottom is placed first so that the bearing does not directly contact the container. When 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.
Fine washing is to carefully clean the bearing while rotating it in the cleaning oil. In addition, the cleaning oil should always be kept clean.
In order to judge whether the removed imported bearings can be reused, check the bearings after cleaning, carefully check the raceway surface, the rolling surface, the mating surface state, the wear of the cage, the increase of the bearing clearance and whether there is any size. Damage and abnormality with reduced accuracy. For non-separable ball bearings, use one hand to support the inner ring and rotate the outer ring to check if it is smooth.
