摘要
本文以螺旋运动为出发点，对啮合理论和机构分析中经常用到的瞬时轴、瞬轴面和啮合轴进行了深入的探讨，并且用微分几何和解析几何方法，论证了瞬轴面的特性。
In this paper writer starts off with helical motion,deeply discusses instantaneous axis,instantaneous axial surface and meshed axis that are often applied to meshed theory or mechanismic analysis.writer demonstrates yet specific property of instantaneoas axial sur-face in the light of method of differential geometey and analytic geometry.
