To avoid sliding that occurs in cylindrical roller thrust bearings, the taper Angle of the rollers is selected so the extended contact lines intersect on the bearing axis.
为了避免推力圆柱滚子轴承发生滑动，滚子的锥度要合适以至于扩大的接触线可以与轴承轴相交。

Rolling theoretical rotation axis line of the inner ring to the center axis line of bearings, thrust bearings on the shaft circle refers to the axis line.
滚动轴承的理论旋转轴心线，对向心轴承即内圈轴心线，对推力轴承则指轴圈轴心线。
