INA plane caused by bearing cage of fracture repair methods

First: plane 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: INA bearings creep phenomenon 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 shaft or shell ring circumferential direction location deviation phenomenon. Third: bearing cage material defects cracks, large pieces of different metal inclusions, porosity, bubble and riveting defects of nails, nail mat or half cage in combination with surface gap, riveting injury etc are likely to cause serious maintains a fracture. Fourth: poor bearing lubrication problem plane 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. Fifth: INA 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. Repair methods & # 8226; Preparation: dry towel, clamp, plane bearing cleaning night, INA bearing lubricating oil or grease. 一个。 Unload C type ring and cover: with a dry towel to bearing external wipe away the dirty things, and then use sharp pliers to live C word on one side of the ring, take C type ring and shield. b。 INA bearings cleaning fluid, soaked the bearing in the bearing cleaning fluid in the market to buy, and shaking at this point, the surface bearing the internal foreign bodies will be shaking out, some stores to buy ultrasonic cleaner to remove the foreign body is also very helpful. c。 Drying: take out the bearing from the cleaning fluid, with a dry towel wipe cleaning fluid, in the shade to dry again. d。 Injection of lubricant, according to the trend to inject grease or oil in the bearing cover cover and replace C type ring. e. Detection: to have been assembled into the original state of INA bearings with finger caught several times after the inner ring rotation.
