Working principle
Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load. When it only bears radial load, the contact angle is zero. When the deep groove ball bearing has large radial clearance, it has the performance of angular contact bearing, which can bear large axial load. The friction coefficient of deep groove ball bearing is very small and the ultimate speed is very high.
Bearing characteristics
Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the bearing radial clearance is increased, it has the performance of a certain angular contact ball bearing, which can bear the joint load of the diameter and the axial direction. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other bearings of the same size as deep groove ball bearings, this type of bearing has small friction coefficient and high limit speed. But it is not resistant to impact and is not suitable for heavy load. [2]
After the deep groove ball bearing is mounted on the axis, the axial displacement in the two directions of the shaft or shell can be restricted within the axial clearance range of the bearing, so the axial orientation can be made in the direction of the axial direction. In addition, this kind of bearing has a certain ability to adjust the heart. When it is 2 '~ 10' relative to the shell hole, it can still work normally, but it has a certain effect on the bearing life. |
