该类轴承能够同时承受径向载荷和轴向载荷,也可以承受纯轴向载荷,能在较高的转速下工作。 |
|
|
单列角接触球轴承只能承受一个方向的轴向载荷,承受轴向负荷的能力由接触角决定,接触角大 |
|
|
,承受轴向负荷的能力高, 但接触角越小则越有利于高速旋转。接触角α的定义为,径向平面 |
|
|
上连接滚球和滚道触点的线与一条同轴承轴垂直的线之间的角度。按接触角度的不同分为: |
|
|
1、接触角α=15°,后置代号为C,多用于较大尺寸精密轴承,如7005C; |
|
|
|
|
2、接触角α=25°,后置代号为AC或A5,多用于精密主轴轴承,如7005AC; |
|
|
|
3、接触角α=30°,后置代号为A,多用于精密主轴轴承,如7005A; |
|
|
|
|
4、接触角α=40°,后置代号为B,适用于承受较大的轴向载荷,如7005B; |

单列角接触球轴承只能承受一个方向的轴向载荷。此类轴承在承受纯径向载荷时,由于滚动体载荷作用线与径向载荷作用线不在同一径向平面内,产生内部轴向分力,所以必须成对安装使用。 |
