Cleaning And Repairing Methods Of Diesel Generator Rolling Bearings

May. 09, 2022

Under normal circumstances, the rolling bearing of diesel generators is relatively wear-resistant, but improper assembly, improper sealing, insufficient lubrication or impure grease, and foreign matter entering the bearing will cause premature wear of the rolling bearing. In addition, when the journal and the bearing inner ring, the end cover hole and the bearing outer ring rotate, the bearing will also be worn. The degree of wear can be judged according to the clearance to decide whether to replace the bearing. In addition, you should also check whether the bearing has cracks, rust, and whether the rotation is flexible.


If there is a lot of looseness between the bearing and the end cover hole, you can use a steel chisel to chisel a row of marks on the circumference of the end cover bearing chamber, and use the burrs on the surface to clamp the bearing outer ring, but this is only an emergency measure and cannot be used for a long time.


If there is rust on the processing surface (especially in the raceway), it can be cleaned with 00 grit sandpaper and then washed in gasoline. If there are deep cracks or broken inner and outer rings, the bearing should be replaced.


When the bearing is damaged, several types of bearings can also be disassembled and assembled into a single bearing using the intact parts. For bearings with fewer balls or balls that are partially damaged. Only the balls can be replaced without having to replace the entire bearing.

If there is a slight noise when the bearing is running, it must be cleaned. When cleaning, remove the grease first, and then clean with a clean brush or a rag dipped in gasoline, at least 2 to 3 times. At the same time, the bearing should be rotated to prevent hair, wire and other debris from being involved in the bearing. In addition, for ease of cleaning, it is best to use hot oil to clean. After cleaning, check the bearing. If there is no obvious looseness and no defects on the ball surface, add grease and continue to use. If not inspecting the inside of the bearing or replacing the bearing, but just cleaning the bearing, it is not necessary to remove the bearing from the shaft.
