Bearing cleaning: remove bearing repair, first recorded bearing appearance, confirming the remaining amount of lubricant, sampling inspection after the use of lubricants, cleaning roller bearing. As a cleaning agent, general use gasoline, kerosene. Remove the bearing cleaning, cleaning and fine cleaning thick, is placed in the container, the metal net first, make the container dirt does not directly contact the bearing. Rough wash, if the bearing rotating dirt, damage the bearing rolling surface, should pay attention to the. In the crude oil washing, with a brush, to remove grease, adhesive material, general cleaning, washing into a fine. Wash wash oil rotation on the side of the bearing, careful cleaning. In addition, the cleaning of oil must be kept clean
Bearing maintenance and judgment: to determine whether it can be used to clean after checking the bearing dismounting bearing. Check the raceway, raceway, cage wear, surface state, bearing clearance and size accuracy, has nothing to do with the injury, abnormal. Non separation of small ball bearings, the inner ring, with one hand support level, rotate the outer ring to confirm. Tapered roller bearings and other separation-shaped bearings, rolling body, the outer ring raceway was examined road surface. Large bearings, because they can not rotate with the hand, pay attention to check the rolling body raceway, cage, wall, such as the appearance of the rolling bearing, high importance, be more careful examination.
For bearings in the bearing load, the axle hole with the axis, use the middle ring to prevent installation of tilt and rotate the outer ring. It should be remembered that, ball bearing some dimensions of the ball projecting from the side of the rolling bearing, so the middle ring should be installed concave, to prevent damage to the ball. A large number of bearings are generally mechanical or hydraulic pressure into the method of installation.
For bearings, the inner ring and the outer ring can be installed separately, thus simplifying the installation process, especially when the rings are required when an interference fit. In the bearing box fits in with the outer ring is installed inside, must pay attention to see whether the right of the inner and outer ring, to avoid scratching the bearing raceways and rolling elements. If the cylindrical and needle roller bearings without flanges flanges of the inner ring or side of a flange ring, the recommended installation sleeve. Sleeve diameter should be equal to the inner ring raceway diameter F, machining tolerances should be d10. Stamping outer ring needle roller bearing is best to use a core shaft installation. Lubrication principle of rolling bearing and rolling bearing lubrication are basically the same, only the bearing working condition is bad, its performance can obtain effective lubrication depends to a large extent on the bearing.
