Motor bearings cleaning method

2020 - motor bearing cleaning method 12 - 16 motor bearing is in commonly used after 2000 hours, should be cleaning and oiling, check and maintenance. Motor bearings cleaning method has the following two types: a, hot oil cleaning method this method, mainly used in the soft dry oil or rust cream hardening of motor bearings, should dip in 80100 ℃ of hot oil, clamp the motor bearings with forceps, brush with wool clean oil motor bearings. Soft dry oil or rust paste is heated to 80 - 100 ℃ will melt, it is easy to flush out from a crack in the motor bearings. Sometimes as long as the motor bearings repeatedly shaking inside the oil, the oil into crevices from. When clean the centripetal spherical motor bearings of motor, you should put the ball, pearl frame transverse transfer from the outer ring, internal ring into hot oil, again after a short cylindrical roller bearing motor when cleaning roller, beads, also should be the inner ring and outer ring off. In the hot oil when cleaning, the oil temperature should not exceed 120 ℃. If use flame directly heating, should pay attention to prevent the oil burning, motor bearings to hang in the pan, sink will cause overheating and reduce hardness. Second, the general cleaning method 5 - put the motor bearings in kerosene 10 minutes, squeeze the inner ring with one hand, another hand turn the outer ring, dry oil or rust on the motor bearing cream will fall down. Then put the motor bearing into the cleaner in kerosene, with soft hair brush to wash, wash oil inside the ball and crack, put them in gasoline cleaning, put out with clean paper. The centripetal spherical ball bearing of the motor and short cylindrical roller bearing motor when cleaning should be ball, pearl, the inner ring and outer ring off to clean. Mounted on the shaft of motor bearing cleaning, relied on pour oil or oil gun spraying method, easy to wash off the oil with kerosene after first use gasoline; Difficult to clean off the oil, with 80 - first 100 ℃ hot oil leaching or oil gun spraying, and then clean with gasoline. It is important to note that don't use sharp tool scraping the motor bearing on hard dirties or corrosion, so as to avoid damage to the motor bearing ring parts of the finish rolling body and groove, wash the motor bearings with a clean dry cloth.
