The slewing bearing does not rotate. Generally, there are three situations. 1. The new slewing bearing purchased cannot be turned. 2. The slewing bearing cannot be rotated after it is installed. 3. The slewing ring cannot be turned during the use of a certain period of time. In this case, the reasons for the analysis and the methods for handling are analyzed.
1. The purchased new slewing bearing cannot rotate
The new slewing bearings purchased are generally subject to stringent inspections and are generally qualified products. The reason for the problems may be that the slewing ring is placed for a long time. In particularly cold areas, impurities such as salt spray are mixed into the raceways, resulting in poor operation. Remedy: If you can run after the increase and no other abnormalities can be used normally.
2, can not rotate after installation
Mainly because the mounting surface of the main unit does not match with the mounting surface of the slewing bearing, the axial clearance of the slewing bearing after installation cannot compensate for the deformation of the slewing bearing. The slewing bearing is in a state of negative clearance, and the rolling elements are difficult to operate in the raceway. The solution ensures the slewing bearing. The consistency of the mounting surface and the host mounting surface.
3, slewing bearing use a period of process can not turn
Generally, the slewing ring seal is broken, causing foreign matter to enter the raceway. The solution is to replace the seal and remove foreign matter.
