The Slewing Ring Bearing point is an indispensable part of mechanical products. If the rotation of the Slewing Ring Bearing point is inflexible and the machine is underpowered and may not work properly, what is the reason for the difficulty in turning the Slewing Ring Bearing? how to fix.
1. Common reasons for the difficulty of slewing bearing rotation
1. The turnover support of new purchases is difficult to idling
If the newly purchased Slewing Bearing has no work damage and the air combat is not smooth, there are generally the following reasons.
(1) The production date is relatively long, the storage is improper, the bearing is corroded, and the rotation is not smooth.
(2) The trauma caused during transportation leads to deformation of parts and unsmooth rotation.
(3) The weather is cold, the viscosity of the grease in the bearing roller is high, and the rotation is not smooth.
2. It is difficult to rotate after installation
(1) The installation position is not flat, and it is not installed according to the plane or padding required for installation, the bearing clearance cannot compensate for the bearing deformation, the Slewing Ring Bearing point is in a clearance state, and the bearing does not run smoothly.
(2) The meshing of the large and small gears of the slewing bearing is not good. Or foreign objects are caught in the large and small gears.
(3) The bearing seal is damaged, and foreign matter enters the drum.
(4) Difficulty in fixing or rotating caused by broken teeth or gear deformation at the rotating support.
(5) Overload operation causes the Slewing Ring Bearing point to not rotate smoothly.
(6) Slewing Ring Bearing lacks lubricant, making it difficult to work with steel balls.
Second, the solution to the difficulty of slewing bearing rotation
1. Difficulty in rotation caused by cold will improve the ambient temperature, then try to run. If it is not yet flexible, the Slewing Ring Bearing points that can withstand low temperatures will need to be replaced according to the local environment.
2. Check the bearing appearance for serious injuries, if so, contact the factory for processing. If rusted, the rust can be removed or replaced with a new bearing.
3. If there is a problem with the installation plane, you can reprocess the host installation plane or charge it with a gasket to keep the installation plane flat.
4. The bearing clearance can be adjusted according to the size of the gear meshing side clearance. Pay particular attention to locations with large gear runout. Also, make sure that there are no foreign objects in the meshing positions of the large and small gears. Swivel bearings with a slightly larger exchangeable clearance cannot be adjusted.
5. Lubricate the bearings regularly and replenish grease in time.
6. If the sealing strip is damaged, the gear is damaged, or the roller is faulty, etc., the manufacturer should be contacted for replacement.
Slewing Ring Bearing points can be difficult to turn for a number of reasons. Adjust or replace the Slewing Ring Bearing points according to the specific problem. If you have any questions about slewing rings, you can contact Slewing Ring Bearing manufacturer Zhiyuan factory by phone at any time, and we will provide you with a satisfactory answer.
