摘　　要：文章根据渐开线齿轮几何学的基本原理,在总结实际工作经验的基础上,提出了一种简捷实用的齿轮逆向设计方法,该法基于公法线长度,特别是量球跨距的精确测量,结合工程计算软件Mathcad,直接准确地确定被测齿轮副的模数、压力角、螺旋角、变位系数等基本参数。该法所用工具简单,测量精度高,实现简便,是一种实用的齿轮设计方法。本方法也适用于渐开线花键的逆向设计。This article is based on the basic principles of the involute gear geometry, summarizing practical experience onthe basis of mapping work, we propose a simple and practical gear reverse design method based on the span length, inparticular the precision measurement of dimension over balls, combined with engineering calculation software Mathcad,accurately determine gears modulus, pressure angle, helix angle, profile shift coefficient. It is a practical design method ofgear, with simple tools, high measurement precision, simple and convenient.The method does also apply to involute spline reverse design.
