The wear modes in rolling bearings are adhesive wear, abrasive wear, corrosion wear, fretting wear, etc. In the case of smoothness, the relative movement is prone to adhesive wear; even burns, external dust entering the bearing, smoothing agent is rich in impurities, bearing clearance Unclean, etc.; will cause abrasive wear, moisture, moisture and acid or alkali solution intrusion into the bearing will cause corrosion and wear, the bearing will not rotate and will be fretting wear under the small oscillation state for a long time.
Wear causes the bearing parts to be rough; the radial clearance increases; the rotation accuracy decreases; the oscillation noise increases; the collision torque increases; the end causes the failure. The bearing always loses the cumulative total number of revolutions of its normal operation function due to wear; or The number of hours of operation at a certain speed is taken as the wear life of the bearing.
At present, only the increase in the radial clearance of the bearing caused by wear is taken as the target of the bearing wear degree; according to the bearing type, the scale and the skill requirement of the bearing to the bearing; the increase of the radial clearance can be determined; the allowable diameter of the bearing is reached. The number of hours of operation before the increase in clearance is the wear life of the bearing.
