锥蜗杆是一个正截头圆锥体,具有一头或几头等导程的螺纹(图1)。包络锥体是节面。因为锥蜗杆是锥蜗轮付的限定构件,所以这一锥体叫做原始节圆锥体。锥蜗杆的外径d。是截头圆锥体的最大直径。一般认为锥蜗杆的圆锥体相对于其轴线的锥角为5°时是标准的。
Cone worm is a straight truncated cone, with one or several equal-lead threads (Figure 1). Envelop cone is a nodal plane. Because the cone worm is a cone worm gear pay the limiting member, so this cone is called the original section cone. Cone worm diameter d. Is the maximum diameter of the frustum. It is generally accepted that the cone of a cone worm is 5 ° cone angle with respect to its axis.
