The main wear forms of jaw crusher eccentric shaft are serious wear of journal and eccentric section journal, excessive bending of axis and fatigue fracture. If the axle is straightened and replanted, the repair process is very complicated, and the repair quality is not easy to guarantee. Therefore, it is seldom used. If such a phenomenon occurs, only scrap or use the material of the shaft for other purposes.
Causes of failure:
1. The internal clearance of the bearing has not been calibrated.
2. During the production process, the crushed stone and powder produced by crushing materials enter into the bearing and cause wear and tear.
3. The lubrication work is not in place.
Resolvent:
If the wear is serious, the eccentric shaft should be replaced in time; if the wear is slight, the bearing can be re-turned on the lathe to achieve the correct geometric shape. It is also the most important thing to do well the lubrication work of bearings, reduce the overload work of equipment and reduce the wear degree of bearings.
