How to clean motor bearings

After the motor has been used for a long time, the bearing parts of the engine should be cleaned and oiled after 2000 hours of operation. The following is a brief analysis of the cleaning method of the motor bearing for the user.

1. Hot oil cleaning method, after long-term use, immerse the motor bearing hardened by dry oil or anti-corrosion paste in hot oil at 100-200 °C, clamp the motor bearing with pliers, and use a brush to clean the oil stains on the motor bearing brush. When the soft dry oil or anti-rust paste is heated to 100-200 ℃, it will melt, and it is easy to wash out from the gap of the motor bearing. Just shake the motor bearing in the oil for many times, and the oil will flow from the gap. Walk.

It should also be noted that the oil temperature should not exceed 20°C during hot oil cleaning. During direct open flame heating, hooking the motor bearing into the oil pan and sinking to the bottom can cause overheating and a reduction in hardness.

2. Soak the motor bearing in oil for 5-10 minutes, hold the inner ring with one hand, and turn the outer ring with the other hand, the dry oil or anti-corrosion paste will fall off the motor bearing. Then put the motor bearing into clean kerosene, apply it with a soft brush, wipe off the oil stains in the ball and the gap, then dip it in gasoline to clean it, take it out and put it on a clean paper. When cleaning radial ball motor bearings and short cylindrical roller motor bearings, the balls, ball cages, and inner and outer rings must be cleaned separately.

Cleaning the motor bearings mounted on the shaft mainly depends on the method of oil spraying or spraying with an oil gun. , Oil stains that are easy to be cleaned off first use kerosene and then gasoline; oil stains that are difficult to clean, first rinse with hot oil at 100-200°C or spray with an oil gun, and then clean with gasoline. Be careful not to scrape the hard grease or rust off the motor bearings with sharp tools, otherwise the rolling smoothness of the motor bearings and grooved rings will be damaged. The cleaned motor bearing can be wiped dry with a cloth.
