摘要: :基于非圆形节曲线的非圆齿轮设计和计算要比圆齿轮复杂得多。由于非圆齿轮各轮齿的形状不尽相同,因此无法使用阵列、镜像等方法进行建模。目前的三维机械CAD软件还不能直接进行非圆齿轮实体建模。文章利用Visual Basic语言对三维软件SolidEdge进行二次开发,实现了齿轮的根切校验、凸性校验、压力角计算等功能,建立了非圆齿轮的三维建模系统,为非圆齿轮三维建模参数化设计提供了一种方法。生成的齿轮三维实体可用于装配设计、运动仿真及计算机辅助教学中。

Abstract: Design and calculation of non-circular gears based on non-circular pitch curves are more complex than circular gear’s. Because of variety of tooth shape, non-circular gears can not be used to model by arraying, mirroring and other methods. The current three-dimensional mechanical CAD software cannot directly model non-circular gears. Using Visual Basic language to carry on secondary development of SolidEdge, it can realize the function of root cutting check, convexity check and pressure angle calculation, can establishe a three-dimensional modeling system of non-circular gears, can provide a method of three-dimensional modeling parametric design for the non-circular gears. The generated gears can be used for assembly design, motion simulation and computer-assisted teaching, etc.

Key words: computer application, three-dimensional modeling, parametric design, non- circular gears
