圆锥滚子轴承的内、外圈具有锥形滚道，滚道之间装有锥形滚子，圆锥滚子轴承主要用城承受以径向负荷为主的径向，轴向联合负荷。轴承的内组件和外圈可以分离，方便了安装和拆卸。轴承的轴向承载能力由接触角α决定，α角越大，轴向承载力越大。

There is much difference between the stress ratio in crown and springe calculated with these two methods. In the crown, most external forces changing into horizontal forces leads to the large decrease of the vertical tension stress. The vertical distribution pattern of the axial forces in the arch and soil pressure is not the same. And near the bottom of the pit the axial tension stress appears. Due to the self-accommodation effect which the external force acts on the arch, the stress in the springe gets lesser too.

拱冠和拱脚处的应力比值跟竖向构件比较相差悬殊；拱冠处由于大部分外力转化为水平拱内轴压力而使得竖向拉应力大大减小；竖向上拱内轴力与土压力的分布模式并不相同，并且在坑底附近出现了轴拉力；拱脚处也由于拱体对外力的自我调节作用而变得比纯竖向构件小的多。

It simulation results proves that when the inner pipes in the concentric annulus pipes stand still, the turbulent flow nucleus area approaches inner pipes; and when inner pipes circumvolve, the turbulent flow nucleus area approaches outer pipes. The shearing velocity near the inner pipes is the biggest, and the shearing velocity increases with the velocity of the inner pipes increasing.

模拟结果表明：在同心环空管道中当内管静止时，紊流核心区即轴向速度最大值区域靠近内管壁；当内管旋转时，紊流核心区即轴向速度最大值区域靠近外管壁；靠近内管壁处的切向速度最大，且随着内管转速的增加切向速度增大。
