Dongying Slewing Bearing.. ! / , -First of all, we should clearly understand what is the rolling bearing clearance and what are the main causes of the clearance. If we cannot understand these two issues, we will not be able to continue looking down. Let’s give a brief introduction first. Proper preload at normal operating temperatures depends on the load on the rolling bearing. Angular contact ball bearings or tapered roller bearings can support both radial and axial loads. Under radial load, an axial force will be generated in the bearing, which is generally borne by the second bearing.
< / , -: - ! / , -In a bearing configuration consisting of two single row angular contact ball bearings or two tapered roller bearings back to back or face to face, each rolling bearing must withstand the axial force from the other bearing. force. When the two bearings are the same, the radial load acts on the center of the two bearings. If the rolling bearing configuration is adjusted to zero clearance, the load distribution can be automatically achieved when half of the rolling parts bear the load. It should be remembered that rigidity is affected not only by the elasticity of the bearing, but also by the elasticity of the shaft and housing, the mounting fit of the rolling bearing rings, and the elastic deformation of all other components in the stress field, including the bearings. These factors have a considerable impact on the elasticity of the entire shaft system.
