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.; the abrasive wear will occur, moisture, moisture and acid or alkali solution will invade the bearing and cause corrosion and wear. The bearing will not rotate and will be fretting and wear under the small oscillation state for a long time.
The damage 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 the normal operation function; or The number of hours of operation at a certain speed is called the wear life of the bearing.
At present, only the increase of bearing radial clearance caused by wear is taken as the target of bearing wear degree; according to the type and scale of the bearing and the skill requirement of the bearing to the bearing; the allowable increase of radial clearance can be determined; when the bearing reaches the allowable radial direction The number of hours of operation before the increase in clearance is the wear life of the bearing.
