圆锥滚子贯穿式超精研机理分析

传统认为圆锥滚子贯穿式超精中，超精导辊螺旋面全长保持一个工作角度，即导辊单角度超精时，滚子的上素线应保持水平状态。分析认为，上素线保持水平状态不是滚子的理想姿态，理想姿态是小端略高的状态，并分析滚子的凸度超精加工机理和影响凸度对称性及凸度量大小的因素。

Analysis on Mechanism of Running-Through Superfinishing of Tapered Roller

Traditionally,when the superfinishing guide roller holds a working angle,the upper generatrix of roller should be hold in level state in the running through superfinishing of the tapered roller.It is find that this state is not ideal,the ideal state is high in small end of the roller in this paper.The superfinishing mechanism of roller crowning and the factors affected crowning symmetry and crowning amount have been analyzed.
