First of all, if the structure design is reasonable and advanced, it will have a longer bearing life. The manufacture of bearings generally goes through multiple processing processes such as forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of each processing technology will also affect the life of the bearing. Among them, the heat treatment and grinding processes that affect the quality of the finished bearing are often more directly related to the failure of the bearing. In recent years, the research on the metamorphic layer of the bearing working surface shows that the grinding process is closely related to the bearing surface quality. The metallurgical quality of timken bearing materials used to be a major factor affecting the early failure of rolling bearings. With the advancement of metallurgical technology (such as vacuum degassing of bearing steel, etc.), the quality of raw materials has been improved. The proportion of raw material quality factor in bearing failure analysis has dropped significantly, but it is still one of the main influencing factors of bearing failure. Whether the material is selected properly is still a factor that must be considered in bearing failure analysis. The main task of timken bearing failure analysis is to find out the main factors causing bearing failure according to a large number of background materials, analysis data and failure forms, so as to propose improvement measures in a targeted manner, prolong the service period of the bearing, and avoid the sudden occurrence of the bearing. early failure of sex. Cleaning of Cylindrical Roller Bearings When removing a cylindrical roller bearing for maintenance, first record the appearance of the bearing, confirm the residual amount of lubricant, and then wash the bearing after sampling the lubricant for inspection. As the cleaning agent, gasoline and kerosene are generally used. The cleaning of the dismantled bearing is divided into coarse cleaning and fine cleaning, which are placed in the container respectively, and the bottom of the metal mesh is placed first, so that the cylindrical roller bearing does not directly contact the dirt of the container. During rough cleaning, if the cylindrical roller bearing is rotated with dirt, it will damage the rolling surface of the bearing, so be careful. In the rough cleaning oil, use a brush to remove grease and adhesions. After it is roughly clean, transfer to the fine cleaning. Fine cleaning is to carefully clean the cylindrical roller bearing while rotating in the cleaning oil. In addition, the cleaning oil should always be kept clean. Cylindrical roller bearing oil mist lubrication and other lubrication methods 1. The oil mist can be dispersed with the compressed air to all the friction parts of the timken bearing that need to be lubricated. A good and uniform lubrication effect can be obtained. 2. Greatly reduce the consumption of timken bearing lubricating oil. 3. The compressed air has a small specific heat and a high flow rate, which can easily take away the heat generated by the friction of the timken bearing. 4. Because the oil mist has a certain pressure, it can play a good sealing effect, avoiding the intrusion of external impurities and moisture into the friction pair of the cylindrical roller bearing. 5. Compared with the thin oil circulating lubrication system, the structure is simple and light, the floor space is small, the power consumption is low, the maintenance and management are convenient, it is easy to realize automatic control, and the cost is low.
