单列圆锥滚子轴承主要应用于以径向载荷为主,同时伴有轴向载荷的工况下,一些大锥角圆锥滚子轴承(22°~31°),则承受以轴向载荷为主的轴、径向联合载荷,一般用于纯轴向载荷的场合。 单列圆锥滚子轴承可以限制轴(或外壳)一个方向的轴向位移,因此可用作单向轴向定位轴承,并且其结构为可分离型,内圈和外圈可以单独安装,且外圈可以互换,安装与拆卸十分方便。在安装和使用过程中,可任意调整径向、轴向游隙,也可以采用预过盈安装以增大轴承刚性。圆锥滚子轴承游隙的大小直接影响轴承的工作性能。当游隙过小时,温升较高;当游隙过大时,振动加大,旋转精度也难以保证。因此,在安装和使用过程中,要特别注意调整轴承的游隙。 为了防止滚子与滚道接触处产生应力集中,造成轴承过早损坏,安装时不允许轴相对于座孔有过大的倾斜,只有当滚子与滚道母线之间为修正线接触时,才能允许有微量(≤2′)的倾斜。由于在径向载荷作用下会产生有附加作用力,因此,一般在轴的两个支承中安装两套单列圆锥滚子轴承,使轴承的内圈和外圈面对面或背对背安装。 单列圆锥滚子轴承多用于汽车后桥轮毂、大型机床主轴、大功率减速器、输送装置的滚轮等
