Can I handle the abnormality of the slewing ring?

2020-06-04

Jiangsu slewing bearing technicians have received feedback from many customers. Some slewing bearings that have just been shipped from the factory will announce the uniform sound of steel balls rolling when idling. Is there a problem with the slewing bearing just bought? The engineer explained that this is a normal phenomenon, but if the normal sound is uniform and accompanied by other abnormal and larger noises, then this situation can be called an abnormal sound.

So, what should customers do, can they handle the abnormal noise of the slewing bearing by themselves? There are several kinds of the above-mentioned situations. One: The slight abnormal noise when the new product is idling will generally disappear naturally after turning dozens of times. If it does not disappear, it may be caused by the slight deformation of the slewing bearing during transportation. However, if the work is flexible and normal, it can be installed and used with confidence, and it will naturally disappear after a period of use. If the noise is loud or does not disappear after a period of use (generally 2-4 months), you should contact Jiangsu Tianyue Slewing Bearing Service Department in time. Two: After assembly, if abnormal noise occurs during trial operation, check whether the mounting surface is flat and meets the requirements, because if the flatness of the mounting surface does not meet the requirements, it will form a negative gap in the raceway and generate abnormal noise. The treatment method is the same as above or the large and small gears have poor meshing , When the tooth is tight and then loose, abnormal noise will occur when the tooth is too tight in the direction where the tooth jumps. Three: Abnormal noise occurs during use.

How to deal with the abnormality of the slewing ring

First, determine whether it is the announcement of the slewing ring. The announcement of some steel structures or other components is often mistaken for the announcement of the slewing ring. Therefore, stop the rotation of the slewing ring and other components can work normally to determine the source of the noise. There are several reasons: the lack of lubricating oil in the raceway, the rolling body and the spacer collide to announce the noise, this kind of noise can be eliminated after timely injection of oil; there are foreign objects in the raceway, such as sand, iron filings, etc., this situation often returns It is often accompanied by difficulty in rotation (generally, this situation is likely to occur in harsh environments); at the same time, attention should be paid to whether the sealing strip is damaged; the loosening of the installation bolts causes the slewing ring to deform elastically, and the deformation direction has negative gaps.
