This paper analyzes the reasons of KOYO bearing vibration fault in the work

KOYO bearing vibration is very sensitive to bearing damage. Such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration zhangs gauge ( Frequency profiler, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal condition in detail. Measured values of bearing or sensor installation position and different using conditions, and thus needs prior to each machine stop after certain discriminant analysis compare measurement value of specification. Imported bearing cage quality that is very good, but in KOYO 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: KOYO 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 bearing operation is in inferior position, 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: KOYO 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: KOYO 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.
