What is the reason for the overturning and shaking of the slewing bearing?

With the rapid development of the machinery industry, slewing ring bearings have been widely used in marine equipment, construction machinery, light industrial machinery, metallurgical machinery, agricultural machinery and other industries. In the process of installation and use, improper use or maintenance of the slewing bearing may bring about various problems. For example, in the use of the slewing bearing, there is a problem of excessive overturning and shaking. What is going on?

1. The mounting bolts are loose, resulting in excessive overturning and shaking during work. When the slewing bearing is shaken, the connecting bolts should be considered first. All the connecting bolts of the inner and outer rings should be checked immediately to see if there is any looseness. If there are any, tighten them according to the torque requirements.

2. The rigidity of the steel structure supporting the slewing ring bearing is insufficient, and elastic deformation occurs when the slewing bearing is under heavy or eccentric load, resulting in the overall overturning and shaking of the slewing ring bearing. This problem is solved by reinforced steel structure.

3. Check whether the operation is seriously overloaded. Overloading will also cause the slewing ring bearing to shake too much, so it must be operated strictly and reasonably according to the regulations.

4. Long-term overload or severe eccentric load operation will cause 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, and it is necessary to contact the slewing ring bearing manufacturer to solve it in time to ensure the normal use of the bearing.

In order to ensure the normal use of the slewing ring bearing, the use and maintenance should be carried out in strict accordance with the “Installation and Operation Manual”. If there is a serious phenomenon of overturning and shaking during use, it must be stopped in time for inspection to prevent long-term sick operation to the slewing ring bearing. cause more damage.

2.How can we increase the service life of the slewing bearing?

Regarding the installation of the slewing bearing, first of all, the stop should be in place, the installation holes should be aligned, and the bolts should be pre-tightened first, and then tightened according to the diagonal method with reference to the tightening torque of different bolts. In fact, there are two main points to pay attention to the installation of the slewing bearing, the first is the installation platform, and the second is the installation method.

The installation platform of the slewing bearing must first have sufficient strength support, and secondly, it must have sufficient flatness. Many people have no problem with the strength of the bearing, but often ignore the flatness of the installation surface. The general accuracy of the slewing bearing produced by Fuji Transmission Higher, the requirements for the flatness of the mounting surface are also higher.

If the flatness of the mounting surface is greater than the parallelism of the slewing ring bearing, when the bolts are tightened, the accuracy of the slewing bearing will be lost, and the slewing bearing will be deformed, and the grooves will be deformed. The dislocation of the slewing ring bearing reduces the service life of the slewing bearing, and the installation platform of the slewing ring bearing is generally machined.

When installing the slewing bearing, check the flatness. For defective positions, you can use the method of adding gaskets. The bonding surface of the slewing bearing and the installation platform should be clean and free of particles and other debris.

The slewing bearing has the position of the soft belt when it leaves the factory, which is generally marked as S. The plug is always the position of the soft belt. When installing the slewing bearing, special attention should be paid to the position of the soft belt. The position of the soft belt should be adjusted to the non-load area or not often.

In the load area, the soft belt area of ​​the inner ring and the outer ring of the slewing ring bearing should be staggered by 180°. When installing slewing ring bearings on some lifting equipment such as truck cranes, cranes and tower cranes, the position of the soft belt should be installed at 90° to the boom.

For the slewing bearing with teeth, the highest position of the tooth runout is generally sprayed with colored paint. Use this position to cooperate with the pinion, and adjust it with a feeler gauge according to the requirements of the national standard.
