圆锥滚子轴承

Tapered roller bearings

圆锥滚子轴承属于分离型轴承，轴承的内、外圈均具有锥形滚道。

该类轴承按所装滚子的列数分为单列、双列和四列圆锥滚子轴承等不同的结构型式。

单列圆锥滚子轴承可以承受径向负荷和单一方向轴向负荷。

当轴承承受径向负荷时，将会产生一个轴向分力，所以需要另一个可承受反方向轴向力的轴承来加以平衡。

Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways.

 This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. 

Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction. 

When the bearing bears the radial load, an axial component force will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance it.
