Slewing Bearing Common Fault Handling
- Nov 27, 2018 -

First, the slewing ring is not flexible


(1) The operation is not flexible after installation, the slewing bearing mounting surface is not well matched, the large and small gears are poorly meshed, the foreign objects in the large and small gears are stuck, the foreign objects on the mounting surface are removed, the gasket is flattened, and the gear meshing backlash is re-adjusted according to requirements. In particular, pay attention to the large position of the gear to jump, check to ensure that there is no foreign matter in the meshing position of the large and small gears.


(2) Inoperative use is inflexible, lacks grease, fills as required, and the seal is damaged, causing foreign matter to enter and roll (if the working condition is poor, roll to the intrusion of dust, etc.); check the meshing of the large and small gears , with or without foreign objects or broken teeth.


Second, abnormal sound


(1) After the assembly, the test operation will have abnormal noise. The treatment method is the same as “the operation is not flexible after installation”, or the large and small gears mesh with each other. When it is tight, it is loose, and the meshing is too tight in the large position of the tooth jump to produce abnormal noise.


(2) Abnormal noise is generated during use, grease is missing in the raceway, and foreign matter such as sand and iron filings are mixed in the pipe. Pay attention to whether the sealing strip is damaged and whether the mounting bolt is loose.


Third, shaking


(1) The mounting bolts are loose, causing them to shake during work. Please inspect all inner and outer ring mounting bolts immediately and tighten as required.


(2) Check whether the operation is overloaded and operate in strict accordance with the regulations.


(3) Long-term overload operation, resulting in raceway crushing and excessive clearance.
