Metallurgical quality of FAG bearings material used to be the main factors affecting the early failure of rolling bearings. As metallurgical technology (such as bearings, such as vacuum degassing of steel) of the progress, raw materials quality has been improved. Raw materials of quality factors in the failure analysis of bearing the proportion has declined significantly, but it is still one of the main factors bearing failure. Selection of propriety are still bearing failure analysis of factors that must be taken into account.
FAG bearings failure analysis of main tasks is based on the large amount of background material, analysis of data and failure mode, identify the main factors causing bearing failure, so targeted for improvement measures, extending the service period of bearing, avoid unexpected early bearing failure.
When removing FAG bearings under repair, bearing the appearance of the first record, confirm that the residual amount of the lubricant, after sampling check of lubricants, and wash bearings. As a cleaning agent, commonly used gasoline, kerosene. Removed bearing cleaning, cleaning rough and fine cleaning, placed in a container, metal mesh on the bottom first, FAG bearings do not directly contact the dirt container. Coarse cleaning, if you rotate the FAG bearings with dirt, can damage the bearings of rolling surface, should be noted. In cleaning crude oil, using brushes to remove grease, stickers, generally after a clean, fine wash. Sperm washing, is FAG bearings cleaning oil on one side rotate, while careful cleaning. In addition, cleansing oils are also frequently kept clean.
FAG bearings-oil-mist lubrication and lubrication method
1, oil mist can compress air diffusion to all FAG bearings require lubrication of friction parts. Can get good and uniform results.
2, significantly reduce the FAG bearing lubricant consumption.
3 small, compressed air specific heat, high velocity, it is easy to take away heat generated by the friction of FAG bearings.
4, because the oil mist has a certain amount of pressure, so you can play a good role, avoiding external impurities, moisture intrusion FAG bearing friction, such as Deputy.
5, a thin oil lubrication system structure is simple and light, covers an area of small, low power consumption, maintenance and management convenience, easy to realize the automatic control, and low cost.
