Dongying City 132.50.3150.002 slewing bearing installation

Dongying City 3..3. Slewing bearing installation / ' (3,3,3) - The slewing bearing is also called the slewing bearing. The slewing bearing is a large bearing that can withstand comprehensive loads and can withstand larger loads at the same time. Axial, radial load and overturning moment, but what should I do if the slewing bearing does not move?
/ ' (3,3,3) -. Please check the production date of the slewing bearing. If it takes a long time (such as more than half a year) ), the climate is cold, salt spray and other impurities may be mixed into the raceway, resulting in poor operation (more prominent in cold areas and winter). Troubleshooting method: If it can operate after adding force and there are no other abnormalities, it can be used normally.
/ ' (3,3,3) -. The operation is not flexible after installation. It may be that the mounting surface of the host machine and the slewing bearing mounting surface do not match well, resulting in the axial clearance of the slewing bearing being unable to compensate for the deformation of the slewing bearing after installation. , the slewing bearing is in a negative clearance state, or there is foreign matter stuck in the large and small gears. Troubleshooting method: Re-process the mounting plane of the main engine to make it meet the requirements. Re-adjust the meshing side clearance of the large and small gears as required. Pay special attention to the maximum position of the gear jump. Check to ensure that there are no foreign objects in the meshing position of the large and small gears. Replace a slewing bearing with a slightly larger clearance.
/ ' (3,3,3) -:. The operation is not flexible during use. The sealing strip is damaged, causing foreign matter to enter the raceway (such as poor operating conditions and dust immersed in the raceway, etc.) Check the meshing condition of the large and small gears to see if there are foreign matter or broken teeth.
