How To Clean The Motor Shaft

How to clean the motor shaft The motor should be cleaned and refueled after 2000 hours of use. There are two cleaning methods for bearings:

1. Soak in 100-200 ℃ hot oil, clamp the bearing with pliers, brush clean the oil on the bearing with a brush. Soft dry oil or anti-rust paste is heated to 100-200 ℃ to melt, it is easy to wash out from the gap in the bearing. Sometimes just shake the bearing in the oil several times. Oil can also flow through the crevices.
   When cleaning the radial spherical bearings of the old motor or imported motor, the ball, the bead frame, the inner ring should be turned out of the outer ring and then immersed in hot oil, and the roller, the bead frame, the inner ring and the outer ring should also be removed when cleaning the short cylindrical roller bearings.

When cleaning the hot oil, the temperature of the oil should not exceed 20℃. If the direct heating with an open flame, attention should be paid to prevent the oil from burning, the bearing should be suspended in the oil pan, the bottom will cause overheating and reduce the hardness.

2. Soak the bearing in kerosene for 5-10 minutes, hold the inner ring with one hand, turn the outer ring with the other hand, and the dry oil or anti-rust paste on the bearing will fall off. Then put the bearing into the cleaner kerosene, wash with a soft brush, wash the oil in the ball and the gap, and then put it in the gasoline to clean once, and put it on a clean paper. When cleaning the radial spherical ball bearings and short cylindrical roller bearings, the ball, the bead holder, the inner ring and the outer ring should be removed for cleaning.
   The cleaning of the bearings installed on the shaft mainly depends on the method of spraying oil or oil gun injection, and the oil that is easy to clean off is first used kerosene and then gasoline; The oil that is difficult to clean off, first wash with 100-200 ℃ hot oil or oil gun injection, and then clean with gasoline. Be sure not to scrape the bearing with sharp tools: hard grease or rust, so as not to damage the finish of the bearing rolling body and groove ring parts, clean the bearing with a clean cloth dry.
