What are the functions of the five major parts of rolling bearings?
In order to avoid unnecessary loss of bearings due to incorrect operation.
Rolling bearings are generally composed of inner rings, outer rings, rolling elements and cages. In addition, lubricants have a great influence on the performance of rolling bearings, so lubricants are sometimes used as the fifth largest piece of rolling bearings.
The functions of the five major parts of rolling bearings: 1. The inner ring is usually tightly fitted with the shaft and rotates with the shaft.
2. The outer ring usually cooperates with the bearing seat hole or the housing of the mechanical part to play a supporting role. However, in some applications, the outer ring rotates and the inner ring is fixed, or both the inner and outer rings rotate.
3. The rolling elements are evenly arranged between the inner ring and the outer ring by means of the cage. Its shape, size and quantity directly affect the bearing capacity and performance of the bearing.
4. The cage evenly separates the rolling elements, guides the rolling elements to move on the correct track, and improves the internal load distribution and lubrication performance of the bearing.
