1. The removal of the bearing mounted on the shaft; mainly by the method of oiling or spraying with oil gun; the oil that is simply removed is first used with kerosene and then with gasoline, it is difficult to remove the oil; first wash with 100 200 °C hot oil Or oil gun eruption; then use gasoline to remove. Must pay attention to not use sharp things to scrape the bearing: hard grease or rust; avoid damage to the smoothness of the imported bearing tumbling and groove ring; clean the bearing with a clean cloth dry. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2. The general cleaning method puts the bearing in the fire oil for 5 10 minutes; the inner ring is pinched by one hand; the outer ring is changed by the other hand; the dry oil or anti-rust cream on the imported bearing will fall off. Then the bearing is placed into the In a hygienic fire oil; rinse with a soft and soft brush; wash the oil in the balls and gaps; remove it in petrol once; remove it and put it on clean paper. Radial ball bearings and short cylinders When the roller bearing is removed, the ball, the bead frame, the inner ring and the outer ring should be disconnected and removed.
3. When removing the centripetal spherical bearing of the old motor or the imported motor; the ball, the bead frame and the inner ring should be laterally turned out from the outer ring and then immersed in the hot oil; the roller should also be removed when the short cylindrical roller bearing is removed. , the bead frame, the inner ring and the outer ring are separated.
When the hot oil is removed; the temperature of the oil should not exceed 20 ° C. If it is directly heated with an open flame; care should be taken to avoid burning the oil; the bearing should be hung in the oil pan, and the bottom will cause overheating and reduce the hardness.
4. The hot oil removal method is used for long-term; soft dry oil or rust-proof paste hardened bearings; should be immersed in hot oil of 100 200 ° C; clamp the bearing with pliers; use a brush to clean the oil on the imported bearings. The oil or rust-proof paste is melted when heated to 100 200 ° C; it is simply washed out of the gap of the imported bearing. Sometimes the bearing is shaken repeatedly in the oil. The oil will also flow away from the gap.
