This paper analyzes the reasons of fracture TIMKEN bearing cage

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. Bearing clean: remove the TIMKEN bearing 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. Imported bearing cage quality that is very good, but in bearing in daily operation, incorrect operation can reduce the service life of bearing cage, even lead to the fracture. Here is to introduce you to introduce what are the conditions will lead to broken bearing cage? First: bearing cage abnormal load installation does not reach the designated position, slope, etc of the large amount of interference of the clearance is reduced, increasing friction heat production, the surface of the softening, abnormal early spalling, along with the expansion of peeling, flaking foreign body into the cage pocket hole, lead to keep running block and generate additional load, aggravated the wear and tear in the cage, the cycle of such deterioration, it may cause maintains a fracture. Second: poor bearing lubrication problem TIMKEN bearing is in inferior position, operation is easy to form adhesive wear and worsen working surface state, adhesive wear of the tear easily into the cage, the cage cause abnormal load, a bracket will be likely to cause fracture. Third: bearing rigid foreign invasion of foreign hard the invasion of the foreign body, exacerbating the cage wear and produce abnormal additional load, are also likely to lead to keep frame fracture. Fourth: bearing creep creep refers to the ring sliding phenomenon, in under the condition of the mating surface interference is enough, because the sliding and make the load point to move around, produce relative axial ring or shell to circumferential direction location deviation phenomenon. Fifth: TIMKEN bearing cage material defect crack, large pieces of different metal inclusion, shrinkage cavity, bubble and riveting of nails, nail mat or half cage joint gap, riveting injury etc are likely to cause serious maintains a fracture.
