Slewing bearing is a bearing used to support the slewing mechanism. Its important function is to enable the driving parts and driven parts to be high-speed seamless connection, in order to achieve the operation of mechanical devices. Slewing bearing has the characteristics of lightness and reliability, which is an important part of lubrication technology and has a wide range of applications.

Types of 1. slewing bearings

There are different types of slewing bearings, including ball bearings, sliding bearings, thrust bearings, thrust ball bearings, contact angle bearings, filter bearings, etc. Ball bearing is a commonly used type of slewing bearing, which has the characteristics of large load capacity, high carrying capacity and high working efficiency. It is the main supporting part of many mechanical equipment.

Structure of 2. slewing bearing

The structure of the slewing bearing is composed of an inner ring, an outer ring, a rolling element and a rolling element seat, wherein the inner ring and the outer ring are installed on the shaft, the rolling element seat is fixed on the casing, and the rolling element is installed between the inner ring and the outer ring To form a supporting structure.

Three, the advantages of slewing bearing

The advantages of slewing bearings are their high transmission efficiency, high reliability, simple structure, convenient maintenance, and good temperature resistance, which can work normally within a certain temperature range. In addition, the slewing bearing can operate normally in harsh environments and has good wear resistance, which can greatly extend the service life.

Selection of 4. Slewing Bearing

The choice of slewing bearing should be based on the working conditions of the mechanical device, taking into account its load, speed, temperature, lubrication conditions, etc., to ensure its normal operation. In addition, when choosing a slewing bearing, pay attention to its installation method to ensure the reliability of its installation.

Maintenance of 5. Slewing Bearing

The maintenance of the slewing bearing should regularly check its appearance, check whether its installation is firm, check whether the rolling body is damaged, and check whether the lubricating oil is contaminated to ensure its normal operation. In addition, replace the lubricating oil in time and clean up the impurities on the surface of the oil film to ensure its good lubricity.

Requirements for the use of slewing bearings: first, the shaft center and the bearing should be in the correct position, otherwise it will affect the normal operation of the bearing; second, when the slewing bearing is installed, the installation accuracy of the shaft center and the bearing sleeve is required to meet the requirements; third, the installation of the bearing needs to be clean, free from damage and any pollutants; fourth, the correct installation and use of the bearing can effectively prolong the service life of the bearing, reduce the number of equipment maintenance. In short, the slewing bearing is an indispensable part of various mechanical devices. Its advantages are strong axial load capacity, low friction coefficient, high transmission efficiency, easy maintenance and high reliability. It is an essential part in the design of engineering machinery. When in use, the shaft and the support are required to be installed correctly. The installation requires high precision, clean installation environment, and correct use to achieve good mechanical properties. The slewing bearing is an important supporting part of the mechanical device, and its quality and reliability directly affect the normal operation of the mechanical device. Therefore, in the selection and use of slewing bearings, attention should be paid.
