The Causes and Solutions of Outer Ring Shaking of the Turntable Bearing

turntable bearings are a commonly used type of bearing in modern machinery, and the requirements for these bearings are relatively high. Improper use or maintenance can lead to various problems, such as the outer ring of the turntable bearing shaking during operation. So what causes the outer ring of the turntable bearing to shake? And how can this problem be solved?

Reasons for the outer ring of the turntable bearing to shake

Structural deformation of steel

The rigidity of the steel structure that supports the turntable bearing is not enough, and elastic deformation occurs when it is loaded, causing the entire turntable bearing to shake.

Loose bolts

Loose installation bolts can cause shaking during operation. When the outer ring of the excavator turntable bearing shakes during operation, all internal and external ring installation bolts should be checked immediately. Check for looseness and tighten according to requirements.

Excessive clearance

Long-term overload work can cause the raceway to be crushed, resulting in excessive clearance. In such a situation, inform the turntable bearing after-sales service to make the necessary adjustments to ensure the normal use of the turntable bearing.

Overload operation

Overloading can also cause the turntable bearing to shake. When the equipment works beyond its rated load, even a precision turntable bearing can shake, and there may be a risk of accidents in severe cases. Therefore, when using the equipment, strictly follow the regulations.

In short, in order to ensure the normal use of the turntable bearing, if there is a shaking phenomenon during use, it must be stopped and checked in time to avoid greater damage to the turntable bearing caused by long-term shaking. How to solve the shaking phenomenon of the outer ring of the turntable bearing?

Methods for solving the shaking of the outer ring of the turntable bearing

Strengthening the strength of the steel structure

When the strength of the steel structure supporting the precision turntable bearing is insufficient, increase the strength of the supporting steel structure by 14 times that of the turntable bearing to ensure the stability of the supporting structure of the turntable bearing and reduce or eliminate the shaking of the turntable bearing.

Regularly tighten

Loose nuts that are tightened can cause the turntable bearing to not be fixed firmly enough. Therefore, they should be re-tightened according to the requirements, and the bolt tightening should be inspected regularly. During machine operation, the nuts may gradually become loose due to normal vibration and operation; therefore, regular inspections are necessary.

Adjusting the clearance

If the clearance of the precision turntable bearing is too large, vibration will occur, which seriously reduces the service life of the bearing. Therefore, adjustments should be made in time. Generally, adjustments are made through the end, based on gear meshing, and the bearing should be flexible and easy to turn.

Do not overload

During operation, pay attention to the rated working load of the turntable bearing and avoid overloading operation. Excessive shaking may occur, which may cause damage to the bearing. Always operate in strict accordance with the equipment specifications.

The above is an introduction to the reasons and solutions for the shaking of the outer ring of the turntable bearing. In daily work, regular maintenance of bearings should be carried out to greatly reduce the failure rate of turntable bearing.
