Thrust bearing is a commonly used mechanical parts in industrial production, not only has the advantages of simple, economical, easy maintenance, and can withstand large axial force, widely used in a variety of large mechanical equipment. However, in the use of thrust bearings, sometimes there will be a strange sound, which seriously affects the stable operation of equipment, then how are these strange sounds caused? And how to solve it?
There are many reasons for the abnormal noise of thrust bearings, and the following mainly introduces a few common reasons:
1. Improper bearing assembly. Most parts of the bearing are very fine parts, and the rotating part of the bearing is very precise. When the thrust bearing is assembled, if it is not assembled according to the standard size of the parts and there is an error, it is easy to cause the bearing to rattle.
2. Poor lubrication. Lubrication is the key to the normal operation of the bearing, the proper lubrication of the bearing should be based on the use of the bearing requirements and environmental characteristics of the selection of the appropriate lubrication, so that the bearing is well lubricated and protected. Inadequate lubrication may cause bearing noise.
3. Bearing life expiration. Bearing life is limited, the use of a long time will be damaged, manifested in excessive wear, fatigue, fracture and so on, resulting in abnormal noise.
How to solve the problem of rattling thrust bearings? The following are the methods to solve the problem of abnormal noise of thrust bearings:
1. Recognize the assembly format of the bearing assembly, especially the permissible error of the bearing ring and the shaft head, which must be assembled according to the size of the bearing and the corresponding reference standard to avoid errors.
2. according to the working conditions and environmental characteristics of the thrust bearing to choose the appropriate lubrication, timely refueling and replacement of lubricants, etc., to ensure that the bearings are well lubricated.
3. regularly check the operation of the bearings, the service life of the bearings, should be replaced in a timely manner to prevent the bearing life due to the expiration of the noise caused by the problem.
In short, the thrust bearing noise problem, we should take positive and effective measures to give the bearing proper maintenance and maintenance, timely treatment of existing problems, to ensure the normal operation of the bearing, to ensure the continuity and stability of industrial production.
