Why does the slewing bearing shake after installation?
Publish time：2021/07/28 News Views：52
With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industry machinery, metallurgical machinery, agricultural machinery and other industries. In the process of installation and use, improper use or maintenance of the slewing bearing may cause various problems. For example, in the use of the slewing ring, there is a problem of excessive overturning and shaking. What is going on? The following is a simple analysis of the reason from Unique Transmission.
1.Loose installation bolts
The installation bolts are loose, causing excessive overturning and shaking during work. In case of shaking when the slewing bearing is working, the connecting bolts should be considered first. All the connecting bolts of the inner rings and outer rings should be checked immediately to see if there is any looseness. If so, tighten it according to the torque requirements.
2.The steel structure supporting insufficient rigidity
The steel structure supporting the slewing bearing has insufficient rigidity, elastic deformation occurs when subjected to heavy or eccentric load, which causes the overall slewing bearing to tilting and shake. This problem is solved by a reinforced steel structure.
Check whether it is seriously overloaded. Overloading will also cause excessive shaking of the slewing bearing. Therefore, it is necessary to operate strictly and reasonably according to the regulations.
4.Overload or severe eccentric load operation
Long-term overload or severe eccentric load operation causes the raceway to be crushed by the rolling elements, resulting in excessive clearance beyond the normal range. If such a situation occurs, the problem is more serious, it is necessary to contact the slewing bearing manufacturer to solve it in time to ensure the normal use of the slewing bearing.
In order to ensure the normal use of slewing bearings, use and maintenance must be carried out in strict accordance with the “Installation Manual“, if there is serious tilting and shaking during use, you must stop the machine for inspection in time to prevent long-term sick operations from causing greater damage to the slewing bearing.
