1.Five common methods of how to deal with 4 points contact ball slewing bearing damage

Slewing bearing, also known as 4 point contact ball slewing bearing, is a new type of mechanical part composed of inner and outer rings and rolling elements. In various construction machinery such as automobiles, cranes, excavators, etc.,

4 point contact ball slewing bearing is to transmit the axial working load of a turntable and chassis , radial horizontal load and overturning torque key element, it can withstand various loads, and can withstand large axial, radial, and overturning moments, it has been well used in industry, but there will also be some question.

How to deal with 4 point contact ball slewing bearing damage
1. Inflexible rotation
If the rotation is inflexible, you can check the production time of the 4 point contact ball slewing bearing first. If the time is longer (such as more than half a year) or the weather is cold.

it is very likely that the viscosity of the grease in the raceway of the 4 point contact ball slewing bearing will increase, resulting in If the work is not working, you need to increase the power, and then restart it. If it still does not work, you must consult the after-sales service in time.

2, does not work after installation
If it does not work properly after installation, there is a high probability that the matching of the host mounting surface and the rotating support surface is not in place, and the mounting surface of the host needs to be processed to meet the requirements, or the washer filling method can be used, and the size can also be adjusted as needed.

The meshing position of the gears, in particular, pay attention to the beating of the gears, and confirm whether there is any debris in the meshing parts of the large gears. If there is a problem that cannot be solved, you can replace a rotating bearing with a larger clearance.

3. Does not work during use
If it does not work normally during use, add grease in an appropriate amount, inject lubricating oil according to regulations, and check whether any impurities enter the raceway. Broken tooth.

4. Abnormal sound
If there is any abnormal sound, you should first check whether the installation surface is flat, or you can stop the rotation of the 4 point contact ball slewing bearing first, and then confirm whether there is grease in the raceway.

This noise can be eliminated after refueling in time. In addition, pay attention to whether the sealing ring is damaged, whether it is the elastic deformation of the 4 point contact ball slewing bearing caused by the loosening of the mounting bolts, or whether there is a negative gap in the deformed part, etc., you can check whether the above conditions are the first.

5. Swing occurs
If rocking occurs, the mounting bolts of the inner and outer rings should be checked immediately and tightened as specified. Or increase the strength of the steel frame of the support, check whether there is overload work, and operate in strict accordance with the regulations.
