本文提出的“直线刃法”,将渐开线齿形的成形过程看作是直线刃与工件(或刀具)运动的线性组合,它可用来分析各种轮齿成形原理,概念清晰、简明,澄清了传统齿轮加工分析中的一些含混概念.本文还对近年来国内外广泛研究、应用直线刃刀片加工齿轮的方法进行了归纳分析,从理论上提出了一种新的齿轮加工方法——径向切齿法. The “linear edge method” proposed in this paper considers the forming process of involute tooth profile as a linear combination of linear edge and workpiece (or tool) motion. It can be used to analyze the forming principle of various gear teeth. The concept is clear, concise, Clarify some vague concepts in traditional gear machining analysis.At the same time, this paper also studies the methods of machining gear with linear blade at home and abroad in recent years, and puts forward a new gear machining method-radial To cut tooth method.
