无侧隙包络环面蜗杆计算机辅助建模

应用啮合原理建立了无侧隙双滚子包络环面蜗杆齿面接触螺旋线方程,并基于蜗杆齿面接触螺旋线方程,提出了两种环面蜗杆三维实体建模方法;第一种为利用MATLAB软件计算生成的*.ibl文件导入Pro/E软件生成蜗杆啮合齿面的方法,第二种为利用Visual C++和Pro/Toolkit接口对无侧隙双滚子包络环面蜗杆进行三维实体精确造型的方法。研究结果表明两种方法都能简捷、高效地获得蜗杆的实际啮合齿面但但第一种方法变更参数复杂,未实现蜗杆的参数化设计,应用对象单一;第二种方法实现了环面蜗杆的完全参数化设计且造型方法适用于所有环面蜗杆。

The Comparative Research on the Solid Modeling Method of the Non-backlash Double-roller Enveloping Hourglass Worm

To solve the complexity problem of three-dimensional solid modeling of the non-backlash double-roller enveloping hourglass worm,the contact helix line formulas of which are deduced by the theories of differential geometry and gear meshing.Based on the above formulas,two new modeling methods of the enveloping worm are presented: one uses the *.ibl files translated from Matlab software and export to Pro/E software to construct the solid model,and the another one uses the Visual C++ and Pro/Toolkit software to...
