So-called bearing burn injury occurs means: SKF bearings roller wheels, rolling elements and cage fever until the discoloration, dramatically softens in the rotation, cladding, and breakage. Selected on the bearing lubricant, and its usage and correct choice of angular contact ball bearings. Research to meet and bearing clearance and preload, and improved sealing device.
1, axle bearing maintenance: in good condition for as long as possible in order to maintain the performance of FAG bearings, maintenance, overhaul, in order to prevent accidents from occurring, ensure operational reliability, improve production and economic nature.
Maintains the best machinery operating conditions operational standards, carried out on a regular basis. Includes monitoring, regular running conditions, supplementing or replacing lubricant remove the check. Maintenance matters in operation, angular contact ball bearings of rotating tones, vibration, temperature, lubricant condition and so on.
2, maintenance of bearings: NSK bearings cleaning removed bearing maintenance, first recorded appearance of the bearing, confirm that the residual amount of lubricant, after checking the lubricant used for sampling, wash bearings. As a cleaning agent, ordinary gasoline, kerosene.
Remove bearing cleaning, heavy cleaning and light cleaning in a separate container, put metal mesh on the bottom so that bearing has no contact with the dirt container. Coarse cleaning, rotate the angular contact ball bearing with a dirt will damage the rolling surface of the bearing, should be noted. Coarse cleaning oil, use a brush to remove grease, adhesive material, after a generally clean, fine wash.
3, bearing maintenance and judgment: in order to determine whether removing bearings can be used to check after the angular contact ball bearings clean. Check the Raceway surface, rolling, status of the mating surfaces, wear of the cage, TIMKEN bearings clearance increases and has nothing to do with precision drop damage, unusual. Non-separation of small ball bearings, the inner ring support level with one hand, rotate the outer ring to confirm fluency.
Internal factors mainly refer to structural design, manufacturing processes and materials quality factors determining the quality of bearing three.
Metallurgical quality of the bearing material used to be the main factors affecting the early failure of rolling bearings. As metallurgy technologies (such as vacuum degassing of steel bearing) advances, improvements in the quality of raw materials. Raw material quality factor's share in bearing failure analysis has already been reduced significantly, but it still is one of the main factors affecting the bearing failure. Material adequacy continue to be bearing failure analysis of factors that must be taken into account.
Angular contact ball bearings generally after forging, heat treatment, machining, grinding and assembling multiple processes. Rationality, advanced processing technology, also affects the stability of the bearing life. Affecting the quality of products INA bearings heat treatment and grinding processes, often has a direct relationship with the bearing failure. On bearing surface degenerating layer of research in recent years indicated that close to grinding and surface quality of bearing.
Main task of analysis of angular contact ball bearing service life, is based on a great deal of background material, analysis of data and failure modes, identify the main factors contributing to failure so that targeted measures for improvement, and extended bearing service, avoid unexpected early bearing failure.
