TIMKEN bearing method of maintenance and overhaul - bearing knowledge

Bearing maintenance for as long as possible in good condition to maintain original TIMKEN bearing performance, 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. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. As maintenance issues in the operation, have bearing the rotation of the sound, vibration, temperature, the state of the lubricants and so on. The overhaul bearing of the bearing cleaning: removing TIMKEN bearings under repair, first record the appearance of the bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make 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 oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, the clean oil is always kept clean. TIMKEN bearing inspection and judgment: in order to judge whether the bearing of the removed can use, check after wash bearing. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. Separation of tapered roller bearings and bearing, rolling body, the outer ring raceway surface can be respectively. Large 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 bearing high must check carefully. Lubricating oil: TIMKEN bearing high performance bearing grease protection, and remove from dirt, foreign body on the surface of the forest. Once bearing removal, than originally will become into the sand, sand and oil adhesion, then more often to wash, so as not to wash. 1, first remove the wheels. 2, remove bearing. After a long run if the bearing is very tight, with hexagonal wrench hard to dig it down. Rest assured, bearing it is not easy to bad! 3, use first toothbrush brushes off the dirt on the surface of the perlin. Some bearing side cover is removable, others are not, to determine whether you are a perlin detachable. ( Note) If at the edge of the bearing side cover, there is a C shape ring, is removable, no, is not to hurt, but there are exceptions. 4, if is detachable, with a word precision screwdriver, along the gap to pry up the C ring, then side cover off. Five, if is not detachable, relatively trouble. To use precision screwdriver into the side cover of seam, forcibly pry up the side cover, as long as the down side, open on both sides is ruined! 6, all the TIMKEN bearing side side cover removed, you can begin to wash. The scouring oil into ceramic bowl, mixed bearing threw a stir.
