What are the main steps in the maintenance of slewing bearings

2020-10-11

The slewing bearing has a wide range of applications in the actual industry. It is called: the joint of the machine is between two objects and needs to do relative rotation motion. At the same time, an important transmission element necessary for machinery that accepts axial force, radial force, and tilting moment is also required. Compared with general bearings, the rotation speed of the slewing bearing is relatively low.

①Following the development of science and technology, the application scale of slewing bearings is now not only in the scope of engineering. Equipment channels such as port equipment, metallurgical equipment, and drilling channels have begun to use rotating bearings on a large scale instead of original bearings. Slewing bearing is a component that realizes the transmission of objects through relative rotational movement. It needs to accept various forces. It is one of the widely used accessories of various mechanical equipment in my country. Therefore, the daily maintenance of the slewing bearing is essential, and the more important maintenance step is rust removal.

②Mainly, it is necessary to keep the surface of the rotating support clean, and to choose a suitable solvent for cleaning according to the appearance of the anti-rust object, so as to avoid the formation of serious corrosion. Surface cleaning can adopt chemical treatment cleaning methods and mechanical cleaning methods. When the surface is dry, do a good job in controlling the temperature. Wait until most of the area is dry before scrubbing it with gauze. When altering the anti-rust oil, different methods should be adopted to alter the appearance of the bearing. Miniature bearings can be directly immersed in anti-rust grease. If you encounter a special shape, you can choose the painting method, so that it is not easy to accumulate. There are many factors that cause metal corrosion. The chemical composition of the metal itself can also cause corrosion or the temperature and humidity of the environment where the article is located.
