KOYO bearing inspection and judgment, clean, replace - bearing knowledge

KOYO bearing cleaning: removing KOYO bearings under repair, the appearance of the first record KOYO bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, KOYO bearings. Common use gasoline, kerosene as a cleaning agent. Tear open come down to KOYO bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, KOYO bearing no direct contact with dirt from the container. Coarse when cleaning, if rotating the KOYO bearings with dirt, can damage KOYO bearing rolling surface, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, KOYO bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, the clean oil is always kept clean. KOYO bearing inspection and judgment: in order to judge whether removed KOYO bearing can use, check after wash KOYO bearing. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of KOYO bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation of small ball KOYO bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. Tapered roller bearing separation KOYO bearing, rolling body, the outer ring raceway surface can be respectively. (2) large KOYO bearing can't rotate with the hand, pay attention to check the rolling element and raceway surface, cage, guard surface appearance, such as the importance of KOYO bearing high must check carefully. KOYO bearing can reuse ( KOYO bearing replacement) Judgment, is considering KOYO 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 KOYO bearings: ( 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 KOYO bearing grease sealed, sealing ring or dust cover breakage is obvious.
