Three-phase asynchronous motor bearing is how to clean? Actually very simple

Three-phase asynchronous motor use after a period of time, if the bearing is not cleaning or washing is not correct, will cause bearing life shorten, the efficiency lower, so the bearing stop care and maintenance is very important, today small make up teach you simple two compare common cleaning bearing method.     Motor used in ordinary should stop cleaning and refueling after 2000 hours. Together to see the bearing cleaning method. One way to clean, compared to conventional ( 1) The bearing in the kerosene soak 5 - 10 minutes, squeeze the inner ring with one hand, another hand turn the outer ring, bearing on the dry oil or rust cream will fall down. Then put the bearing into the clean kerosene, with soft hair brush to wash, put them in gasoline cleaning, comes out on the clean paper. Centripetal spherical ball bearing and short cylindrical roller bearing when cleaning should be ball, pearl, the inner ring and outer ring off to clean. （ 2) Mounted on the shaft bearing cleaning, mainly by radiation to pour oil or oil gun, cleaning off the oil with kerosene after first use gasoline; Difficult to clean off the oil, with 100 - 200 ℃ hot oil leaching or oil gun radiation, then clean with gasoline. Do not use sharp tools scrape of hard bearing oil dirties, in order to avoid damage to the bearings and roller slot ring parts of the brightness, rinse with clean dry cloth. Second, the way of cleaning with hot oil ( 1) Due to the use of long, soft dry oil or rust cream hardening bearing, should dip in 100 - 200 ℃ in hot oil, clamp bearing with forceps, brush with wool clean oil bearing. Soft dry oil or rust creams are heated to 100 - 200 ℃ condensation, very literally from a crack in the bearing of the scour in. Sometimes just put the bearing repeatedly shaking in the oil. The oil into crevices from. （ 2) In cleaning the old motor or import of centripetal spherical bearing, 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 when cleaning roller, beads, also should be the inner ring and outer ring off. （ 3) In the hot oil when cleaning, the oil temperature should not exceed 20 ℃.
