How to use industrial brush to clean motor bearings

1. When cleaning centripetal spherical bearings of old motors or imported motors, the ball, ball rack and inner ring should be turned out of the outer ring. When immersing the outer ring in hot oil, the roller, ball rack and inner ring should also be separated from the outer ring when cleaning motor bearings of short roller.
If the hot oil has been used for a long time, the soft dry oil or the anti-rust paste hardened motor bearing should be immersed in the hot engine oil of 100-200 degrees at this time, and then the main motor bearing should be clamped with pliers. The industrial brush is used to brush the oil dirt on the motor bearing, and the soft dry oil and anti-rust paste above have melted when heated to 100-200 degrees, This can easily be removed from the gap of the bearing of the motor, but sometimes the oil will flow away from the gap as long as the bearing of the motor is shaken in the hot oil for several times.
When the hot oil is cleaned, some temperatures can not exceed 20 ℃. If the open flame is used for heating, attention should be paid not to burn the oil. The bearing of the motor should be suspended in the hot oil. If it sinks to the bottom, it may cause overheating and reduce the hardness.
2. The general cleaning method is to immerse the motor bearing in a basin of kerosene for 5-10 minutes, hold the inner ring with one hand, and then rotate the outer ring with the other hand, so that the dry oil and anti-rust paste on the motor bearing will fall off, and then put the motor bearing in a relatively clean kerosene, and then brush with an industrial brush, so that the oil stains in the ball and the gap are cleaned, Once again, put it in gasoline for cleaning, and then take it out and put it on a piece of clean paper. All kinds of bearings should be cleaned separately from the inner ring and outer ring.
In the process of cleaning the bearing of the motor, the brush plays a very important role, because the brush used cannot be too hard. If it is too hard, it may damage the smoothness of the rolling element of the motor bearing, and it cannot be too soft. If it is too soft, it may not play a role in cleaning. Therefore, it is very important to select the brush, and must select a large brand of special industrial brush.
