环面蜗杆(原名:弧面蜗杆),因其外形为圆环面的一部分,在齿轮名词术语的国际标准和国家标淮(报批稿)中采用此名。它与圆柱蜗杆的本质区别在于:圆柱蜗杆的螺纹面是由刀具母线或母面作直线运动S_1,蜗杆作回转运动ω_1形成的(图1)。环面蜗杆则为刀具和蜗杆分别作ω_2和ω_1两个回转运动形成的。和圆柱蜗杆传动一样,环面蜗杆传动也有几种不同的类型。形成蜗杆的母线或母面可以为直线,圆锥面(圆柱面)、平面、渐开线螺旋面,从而形成不同
Toroidal worm (formerly known as: curved worm), because of its appearance as part of the torus, the terms of gear terms of international standards and national standard (for draft) use this name. It is the essential difference with the cylindrical worm is: cylindrical worm thread surface is made by the tool bus or the mother of the linear motion S_1, worm rotation motion ω_1 form (Figure 1). Toroidal worm is the tool and the worm respectively for ω_2 and ω_1 two rotary motion formed. As with cylindrical worm drives, toroidal worm drives are available in several different types. The formation of worm or busbar can be straight, conical (cylindrical), plane, involute spiral surface, thus forming a different
