摘　　要：主要阐述了通过曲线、曲面、实体的流程进行蜗杆参数化建模的方法。首先进行了柱面坐标系下两个端面齿形的渐开线、齿根圆弧、齿顶圆弧以及螺旋母线的方程推导,讨论了齿根圆大于和小于基圆两种情况的处理方法,完成了单头蜗杆齿槽的线框模型。然后,通过造型工具生成曲面模型,通过旋转绘制蜗杆齿坯,使用曲面实体化切除方法生成实体模型、齿槽阵列、添加参数关系,生成通用圆柱蜗杆的参数化实体模型。The method about parametric mode design of involute worm is introduced followed sequence of line,surface and solid model.Firstly,curve equations,which are involute curves of the two transverse tooth spaces profiles and root and addendum circular arcs and helix generating line,are deduced in the cylinder coordinate system,and problems about tooth root circle greater or less than base circle are successfully resolved.And then,single tooth space surface model is generated through surface styling of it＇s wireframe model.In the end,a common cylindrical involute worm parametric solid model is brought out by the means of drawing worm blank by revolving tool,removing tooth space material using surface solidify tool,tooth space pattern and corresponding parameter relations adding.
