接触球轴承极限转速较高,可以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,并随接触角的增大而增大。
单列角接触球轴承
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。双列角接触球轴承能承受较大的以径向载荷
为主的径向、轴向双向联合载荷和力矩载荷,它能限制轴或外壳双向轴向位移,接触角为30度。
轴承代号:7
成对安装角接触球轴承
成对安装角接触球轴承能承受以径向载荷为主的径向、轴向双向联合载荷,也可以承受纯径向载荷。串联配置只能承受单一方向的轴向载荷,其他两种配置则可承受任一方向的轴向载荷。这种类型
的轴承一般由生产厂商选配组合成对提交用户,安装后有预压过盈,套圈和钢球处于轴向预加载荷状态,因而提高了整组轴承作为单个支承刚度和旋转精度。
轴承代号:0
