Lead to abnormal countermeasures of INA ball screw bearing use damage - bearing knowledge

INA bearing structure design is reasonable and at the same time have improved predecessors, will have a long ball screw bearing life. Bearing manufacturing typically by casting, heat treatment, turning processing, grinding and assembly process. The processing technology of justice, improve the elder, not will also affect the bearing of life. Which affects the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. In recent years the study of metamorphic layer of bearings working surface show that the grinding process tightly close to the surface quality of the bearing. INA bearing materials of metallurgical quality was affected move ball screw the main factors of premature failure of the bearing. Follow the metallurgical technology ( For example, the bearing steel vacuum degassing, etc. ) The increase of raw material quality is improved. Raw material quality factor in the bearing failure analysis share has dropped significantly, but it is still one of the main influence factors of bearing failure. Select material adequacy is still bearing failure analysis should consider factors. The main task of the INA bearing failure analysis, it is based on a lot of background material, analyze data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden. 1, bearing of maintenance, repair, and exception handling for as long as possible in good condition to maintain the performance of the ball screw bearing was required to maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Contents include, monitoring operation status, supplement or replacement of lubricants, remove the check on a regular basis. As maintenance issues in the operation, the rotation of the INA bearing state of sound, vibration, temperature, lubricant and so on. 2, bearing damage and countermeasure of general, if the proper use of INA bearings, can be used to achieve fatigue life. But there will be unexpected injury prematurely, not resistant to use. This early damage, as opposed to a fatigue life, is called the quality using limit of fault or accident. Much due to the installation, use, do not pay attention on the lubrication, intrusion of foreign bodies from outside, to the shaft, shell heat affected study enough. On the bearing damage status, such as: roller bearing ring guard card, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, foreign invasion, ball screw bearing installation error, the deflection of the shaft is too large, also can have these reasons. Therefore, only investigate bearing damage, the real reason is hard to come by injury. But, if you know the bearing on the use of machinery, the structure of the surrounding conditions of use, INA bearing, understanding before and after the accident, in combination with several damage status and causes of ball screw bearing, can prevent the similar accident happen again.
