1. Rework the main unit mounting surface so that the mounting plane meets the requirements or is treated with a gasket filling method;
2. Re-adjust the gear meshing backlash as required, especially pay attention to the maximum position of the gear beat;
3. Check that there are no foreign objects in the meshing position of the large and small gears;
4. Exchange a slewing bearing with a slightly larger gap;
Reasons for the inflexibility of the slewing ring during use:
1. Lack of grease, fill as required;
2. The sealing strip is damaged, causing foreign matter to enter the raceway. If the working condition is poor, the dust is intruded into the raceway;
3. Check the meshing of the large and small gears for foreign objects or broken teeth. If the above measures are taken, the slewing bearing cannot be transferred, and there may be a failure in the raceway. Please inform our after-sales service department.
