Taper roller bearings of the series 313 are particularly adequate due to their comparatively large contact Angle (approximate 30 deg), when high axial forces are to be considered.

圆锥滚子轴承系列313，特别是足够的，由于其相对较大的接触角(约30摄氏度)，高轴向力时要考虑的。

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。

For improving the design reliability and efficiency of the stubble roller, visualized dynamic gap Angle was obtained though drawing blade moving track according to movement equation using ug - NX3.

为提高灭茬刀辊设计的可靠性和效率，基于UG - NX 3软件，根据运动方程绘制刀刃运动轨迹，形象直观的获取动态隙角。
