The function of the automobile shock absorber bearing is to have a shock absorber and the body of the theme activity connection effect, to prevent immediate friction, whether it is in the same direction, or in the direction of the car will have the sound of Gaden Gadeng, at the same time, with the vibration, the direction will also sink. If you get the boost, in the case of destroying the car, the direction will feel like a cut. The bearing ball rotates between the shaft ring and the sitting ring. Only one azimuth radial load can be bearing, not axial load. Because the radial load is evenly distributed on each bearing ball, the load working capacity is very large. However, during operation, the temperature rises very much, and the allowable limit speed is relatively low. The advantage of the plan-plan bearing is that the use of high-precision cylindrical roller bearings (needle rollers) increases the contact length, which allows the bearing to obtain load working capacity and high bending stiffness in a small indoor space. Another advantage is that if the surface of the adjacent parts is suitable for the raceway surface, the sealing ring can be omitted, which can make the design scheme tight, and the round surface of the needle roller and cylindrical roller bearing selected for DF plan needle roller bearing and plane plan cylindrical roller bearing bearing bearing is the modification surface, which can reduce the edge in-situ stress and improve the service life.
