滚动轴承由外圈,内圈,滚动体和保持架四部分组成.角接触轴承极限转速较高,可以同时同时承受径向载荷和轴向载荷,也可以承受纯轴向载荷,其轴向载荷能力由接触角决定,并随接触角增大而增大.单列角接触球轴承只能承受一个方向的轴向载荷,在承受径向载荷时,会引起附加轴向力,必须施向相应的反向载荷,因此,该种轴承一般都成对使用.
轴承损坏及超过使用小时,必须更换.
The rolling bearing is composed of four parts: outer ring, inner ring, rolling body and cage. The angular contact bearing can bear radial load and axial load at the same time, and can also bear pure axial load. Its axial load capacity is determined by the contact Angle and increases with the increase of the contact Angle. Single row angular contact ball bearings can only withstand one direction of the axial load, in the radial load, will cause additional axial force, must apply the corresponding reverse load, therefore, this kind of bearings are generally used in pairs.
Bearings damaged and more than hours of use, must be replaced.
