Outside the spherical bearing damage repair judgment method

For as long as possible in good condition to maintain the performance of the outer spherical 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. Generally, if the correct use of outer spherical bearings, can be used to achieve fatigue life. But there will be unexpected injury prematurely, no ability 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 outer spherical 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, TIMKEN bearing installation error, the deflection of the shaft is too big, also can have these reasons. Therefore, only investigate bearing damage, the real reason is hard to come by injury. However, the use of machinery, if you know the bearing conditions of use, bearing the surrounding structure, to get hold of before and after the accident, combined with several damage status and causes of bearing, can prevent the similar accident happen again. Determine outer spherical bearing can use again, according to the damage degree of TIMKEN bearings, mechanical properties, importance, and operating conditions, the factors related to inspection cycle to decide. But check if found any of the following defects, the bearing can't continue to use, need to replace new TIMKEN bearings. ( a) Inner ring and outer ring, rolling body, any has a crack or breach in a cage. ( b) A: do you have any ring, rolling body fracture. ( c) Rolling surface, guard, has obvious scratches on rolling element. ( d) Cage wear obviously, obviously loose or rivet. ( e) On the raceway surface, rolling body is rust or scar. ( f) On the raceway surface, rolling body has serious indentation or bruised. ( g) Inner ring diameter or outer diameter surface has obvious creep. ( h) Obvious color change due to overheating. ( i) The TIMKEN bearing grease sealed, sealing ring or dust cover seriously damaged.
