Cleaning methods

Soak the motor bearing in kerosene for 5-10 minutes, hold the inner ring with one hand and rotate the outer ring with the other hand, and the dry oil or antirust cream on the motor bearing will fall off. Then put the motor bearing into the cleaner kerosene, wash it with a soft brush, wash the oil in the ball and gap, and then clean it in gasoline once, and put it on a clean paper after taking it out. When the bearings of centripetal spherical ball motor and short cylindrical roller motor are cleaned, the ball, ball frame, inner ring and outer ring should be separated and cleaned.

Motor bearings installed on the shaft cleaning, mainly by dousing oil or oil gun injection methods, easy to clean off the oil with kerosene first with gasoline;Difficult to clean off the oil, first with 100-200 ℃ hot oil rinsing or oil gun spray, and then with gasoline cleaning. It is necessary to pay attention not to use sharp tools to scrape the hard oil scale or rust on the motor bearing, so as not to damage the smoothness of the rolling body and groove ring parts of the motor bearing. The cleaned motor bearing is dried with a clean cloth.

Installation and inspection methods

1. Before checking the bearing, first remove the old lubricating oil of the small cover inside and outside the bearing, and then clean the small cover inside and outside the bearing with the brush gasoline. After cleaning, clean the bristles or cotton silk, and do not leave it in the bearing.

2. Check the bearing carefully after cleaning. The bearing should be clean and intact, without overheating, cracks, peeling, concave groove impurities, etc., the inner and outer raceway is smooth, and the gaps are qualified.

3. After maintenance, the bearing should rotate flexibly without jam phenomenon.

4, check the bearing inside and outside the small cover should not wear, wear should be found out the reason for processing.

5, bearing inner sleeve and shaft should be tightened, otherwise it should be processed.

6. When assembling new bearings, apply oil heating or eddy current method to heat the bearings. The heating temperature is appropriate to 90 ~ 100℃.
