提出一种大胆的设想 ,将圆环面蜗杆毛坯上加工出普通螺旋齿槽 ,利用两侧增加的齿高既可增加接触区 .又可避免环面滚刀无法铲磨及蜗杆加工的专用装置
A bold idea is put forward that the general helical tooth groove is machined on the toroidal worm blank and the contact area can be increased by increasing the tooth height on both sides and the special device for preventing the toroidal hob from being able to grind and worm is also provided
