轴线交叉两回转体相贯线的画法

The Drawing Method of the Intersection Lines of the Two Revolving Bodies on an Axis Cross

本文简要的分析了两回转体相交时，相贯线的各种画法以及各画法所需满足的几何条件。提出了用“贯穿点”求取法，求画“轴线交叉两回转体”相贯线的画法，开发了贯穿点求取法在工程制图中的实际应用，有效地解决了相贯线上特殊点的求画问题。

This paper simply analyzes different kinds of drawing methods and geometoiced conditions needed to met when two intersecting bodies revolves and presents a solution to the problem of breakingthrough point,and this method can be effectively and efficiently used in engineering.
