在小模数齿轮齿形的检测中,通常需要画出放大的标准齿廓。本文提出一种渐开线放大图均匀描点与弦径法制图的方法,供同行们参考。如图1所示,渐开线由起始点S_0至线上任一点的弧长S为:
In the small module gear tooth detection, usually need to draw an enlarged standard tooth profile. This paper presents an involute enlarged uniform point and chord method of drawing method for reference. As shown in FIG. 1, the arc length S of the involute line from the starting point S_0 to any point on the line is:
