用Sykes斜齿插齿刀(即人字齿轮插齿刀,见图1)可以加工中间无退刀槽的人字齿轮,以提高齿轮的机械性能。但是多年来,由于人字齿轮插齿刀刃磨前刃面比较困难,因而人字齿轮插齿刀的使用受到了限制。本文将介绍一种使用一般工厂刃磨人字齿轮插齿刀前刃面的工艺方法。这种开刃的原理是圆弧修正法。人字齿轮插刀开刃是将刀齿前面刃磨成与垂直于其齿向方向成一定角度的面,从分圆柱展开图2可见,锐侧刃被倒棱,而钝侧刃要开沟,开刃面
With Sykes helical gear shaper (ie, herringbone gear shaper, see Figure 1), it is possible to machine herringbone gears without relief grooves in the middle to improve the mechanical properties of the gears. However, over the years, the use of herringbone gear hobbing cutters has been limited due to the difficulty in sharpening the front face of the herringbone gear sharpening tool. This article describes a general factory sharpening herringbone gear shaper cutting edge process. This principle of edging arc correction method. Herringbone gear cutting edge blade is to be ground in front of the tooth edge and perpendicular to the direction of its direction at an angle of the surface, from the cylindrical column opened Figure 2 shows the sharp edge of the blade is chamfered edge, while the blunt side edge to be ditched , Razor surface
