轴承特性
Bearing characteristics
深沟球轴承是最常用的滚动轴承。它的结构简单，使用方便。主要用来承受径向载荷，但当增大轴承径向游隙时，具有一定的角接触球轴承的性能，可以承受径、轴向联合载荷。在转速较高又不宜采用推力球轴承时，也可用来承受纯轴向载荷。与深沟球轴承规格尺寸相同的其它类型轴承比较，此类轴承摩擦系数小，极限转速高。但不耐冲击，不适宜承受重载荷。 [2]
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]
深沟球轴承装在轴上后，在轴承的轴向游隙范围内，可限制轴或外壳两个方向的轴向位移，因此可在双向作轴向定位。此外，该类轴承还具有一定的调心能力，当相对于外壳孔倾斜2′～10′时，仍能正常工作，但对轴承寿命有一定影响。
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.
