1, bearing cleaning removing bearing under repair, first recorded bearing appearance, confirm the residual stock of lubricant, sampling inspection with lubricant, cleaning bearing. Common use gasoline, kerosene as a cleaning agent. Was down to the bearing cleaning, coarse and fine fine cleaning cleaning, respectively in the container, first put on the metal mesh at the bottom of the bearing is not direct contact with dirt from the container. Coarse when cleaning, if to spin bearing with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning is spun bearing in cleaning fluid on one side, and carefully cleaned. In addition, the clean oil is always kept clean. 2, bearing inspection and judgment to judge whether the bearing of the removed can be used again, check after bearing clean, carefully check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the bearing clearance, and presence of dimensional precision, abnormal falling damage. Non separation of ball bearing, the inner ring with one hand supported, the horizontally rotate the outer ring confirm whether under smooth rotation. Tapered roller bearing separation type bearing, rolling body, the outer ring raceway surface can be respectively. Because of large bearing not rotate with the hand, pay attention to check the rolling element and raceway surface, maintain the appearance of the frame, guard, etc. The importance of bearing high must check carefully. Whether can be used to determine, is considering bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. But if you have the following defects can't use, must be replaced new bearing: ( 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.
