What does Slewing Ring Bearing Do?

1. China slewing ring bearing is generally called the connecting part of the machine, which is an essential driving link for the machine. Macroscopically, a slewing ring bearing is called a supporting part often used as the basic component of CNC machine tools. It includes columns, rocker arms, tool holders and bed, as well as beams and lifting tables.

2. There is also a bearing called auxiliary bearing that improves the rigidity of the workpiece, and of course, it also plays its role in limiting the degree of freedom. In other words, the auxiliary bearing facilitates the processing to achieve and improve processing accuracy and efficiency. As different slewing bearings have different installation methods, when imposing a restraint, full restraint can be imposed on the inner surface of the inner ring or the outer surface of the outer ring.

3. Different raceway shapes have a greater impact on the bearing capacity of the slewing ring bearing. The Mises stress of an elliptical raceway is smaller than that of a circular raceway. That is to say, the bearing capacity of the elliptical raceway slewing ring bearing is higher than that of the circular raceway slewing ring bearing.

These parts are relatively large in size, so they are often called large parts. Slewing ring bearing is a kind of large supporting bearing that can bear load in a comprehensive way. It can bear large axial load, radial load and tilting moment at the same time, in order to ensure the normal and stable continuous operation of the equipment. Since the large bearing is an enclosed structure, so the supporting bearing can only play its role when the heavy structure is lifted to a certain height.

4. The height will increase by about 28%. During use, the slewing ring bearing is generally subjected to the combined action of axial force Fa, radial force Fr and overturning moment M. For different applications, the combination of the above three loads will change due to different working methods and structural forms of the main engine. Large bearings may fail to work due to various factors in the process of manufacturing and installation. Under normal circumstances, these faults can be detected through vibration.
