The working principle of roller bearings:
Roller bearings are mainly composed of inner rings, outer rings, rolling elements, and retainers. The inner and outer rings are usually made of high carbon steel, and the surface is quenched to improve hardness and wear resistance.Rolling elements are the core components in bearings, which can be cylindrical, conical, or spherical. They reduce friction and support the shaft by rolling between the inner and outer rings. The function of the cage is to keep the position of the rolling elements stable and prevent them from colliding with each other.When the shaft rotates through the rolling elements between the inner and outer rings, due to the shape characteristics of the rolling elements, it can roll between the inner and outer rings, thereby reducing friction and allowing the shaft to rotate easily. Meanwhile, the number and arrangement of rolling elements also affect the bearing's load-bearing capacity and service life.Industrial machinery: Roller bearings are widely used in industrial machinery, such as motors, reducers, pumps, compressors, etc. In these occasions, roller bearings are used to support the shaft, transmit power, and reduce friction, improving mechanical efficiency and reliability.
