基于4条引导线的直廓环面蜗杆参数化设计

Parametric Design of Straight Profile Hourglass Worm Based on Four Guide Lines

为减少直廓环面蜗杆设计成本,对直廓环面蜗杆的建模过程进行参数化设计。通过空间啮合原理推导齿面方程和4条变径空间螺旋引导线,沿4条引导线方向对直廓环面蜗杆进行建模。使用Visaul Basic 6.0语言对整个建模进行参数化设计,得出了直廓环面蜗杆的齿面方程和引导线方程,完成了自动建模程序。它可输入不同参数建立对应的蜗杆模型,减少了设计时间,提高了工作效率,在实际设计生产工作中具有重要作用。

In order to reduce the design cost of the straight profile toroidal worm,the modeling process of the straight profile toroidal worm was designed parametrically.The tooth surface equation and four variable-diameter space spiral guide lines are deduced by the principle of spatial meshing,and the straight-profile toroidal worm is modeled along the directions of the four guide lines.Use Visaul Basic 6.0 language to parametrically design the entire modeling,obtain the tooth surface equation and guide line equation of the straight profile toroidal worm,complete the automatic modeling program,and input different parameters to establish the corresponding worm model,reducing the design Time improves work efficiency and plays an important role in actual design and production work.
