IKO deep groove ball bearing cage fracture of important factor

Deep groove ball bearing cage fracture belongs to incidental abnormal failure mode, we come from the following five aspects, the author analyzes the reasons of IKO bearing cage fracture. 1 problem: poor lubrication, deep groove ball bearings, IKO bearing operation is in inferior position, easy to form adhesive wear and worsen working surface, adhesive wear of the tear easily into the cage, the cage cause abnormal load, a bracket will be likely to cause fracture. 2, deep groove ball bearing creep phenomenon: creep refers to the ring sliding phenomenon, more in the mating surface interference under the condition of insufficient, because the sliding and make the load point to move around, produce relative axial ring or shell to circumferential direction location deviation phenomenon. 3, deep groove ball bearing cage material defects: crack, large pieces of different metal inclusion, shrinkage cavity, bubbles and riveting defects of nails, nail mat or half cage in combination with surface gap, etc are likely to cause serious injury maintains a fracture. 4, deep groove ball 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. 5, deep groove ball bearing hard foreign invading 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.
