An emergency eccentric bearing damage repair problem as a whole

Generally, if the proper use of the eccentric bearing, can be used to achieve fatigue life. But there will be unexpected injury prematurely, not resistant to use. This early damage, and fatigue life, it is called the fault or the quality using the limit of the 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. About whole eccentric bearing damage status, such as: roller bearing ring, guard card injury, as a reason to consider, lack of lubricant, not suitable for, for the defect of oil discharge structure, the invasion of the foreign body, bearing installation error, the deflection of the shaft is too large, also can have these reasons. Whether can be used to determine, is considering bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. However, if you have the following defects can't use, must be replaced new eccentric bearing: (as a whole a) Inner ring and outer ring, rolling element and cage have crack or gap on any one; ( b) On any one ring, rolling body fracture; ( c) Raceway surface, guard, with significant roller card injury; ( d) Maintains a significant wear and tear, or rivet significant relaxation; ( e) Raceway surface, there are rust on rolling element and injury; ( f) On the raceway surface, rolling body has serious indentation and mark; ( g) Inner ring diameter or outer diameter surface has obvious creep; ( h) Discoloration caused by thermal obvious; ( i) The bearing grease sealed, sealing ring or dust cover breakage is obvious.
