SKF bearing vibration of bearing damage is very sensitive. Such as indentation cracks, wear, corrosion, spalling, are reflected in the vibration measurement of bearing, so, after using a special vibration of bearing vibration measuring device to measure out the size of the frequency cannot be inferred after details of the exception. Measured values from bearing conditions or use of the sensor device location and different, thus needs prior to analysis of the measured value for each machine stop discriminating norms after the match.
Quality cages for SKF bearings are good, but in the day-to-day running of the bearings, improper operation will reduce the life of the bearing cages, or even cause it to break. Introduce below describes what conditions will cause bearing cage fracture?
1. SKF bearing cage abnormal loads
Installation is not in place, tilt, excessive interference prone clearance reduction, exacerbating friction heat, soften the surface, exceptions occur prematurely peeling with the spread of flaking, peeling off entering the retainer Pocket Hole, causing cage run blocking and creates additional load, exacerbates wear of the cage, so the cycle of deterioration, it may result in cage fracture.
2. Poor lubrication of bearings problems
SKF bearing play is in a poor state, formation of adhesive wear, deterioration of the surface condition of work, adhesive wear of tearing into the cage, cage abnormal load, potentially causing cage fracture.
3. SKF bearing hard foreign body penetrated
External hard foreign body penetration of retainer wear with the exception of the additional load, may also cause the cage fracture.
4. Bearing creep phenomena
Creep sliding phenomenon of rings, the mating surfaces without sufficient interference, loads to move around due to the slide, ring shaft or housing in a circumferential direction deviation of the position.
5. SKF bearing cage materials
ISO metal inclusions and shrinkage cracks, large, sparkling nail defects and riveting short nails, pad or half cage surface voids, grave riveted cage of injury, which may result in breakage.
