摆线齿轮滚刀的三维参数可视化设计

Three-dimensional parametric and visual design of cycloid gear hob

为解决摆线齿轮滚刀设计过程的低效、低精度、周期长等问题,应用Auto CAD的二次开发工具Visual Basic of Application,开发出摆线齿轮滚刀三维参数可视化软件.在软件的输入界面中输入摆线齿轮滚刀的主要参数,即可创建摆线齿轮滚刀的三维参数可视化实体模型.再在ANSYS中对摆线齿轮滚刀的三维实体模型进行有限元分析,得出摆线齿轮滚刀的应力、应变、位移云图,通过分析初步得到摆线齿轮滚刀的切削性能和失效形式.

In order to solve problems of inefficient, low precision and long design cycle of cycloid gear hob design process, a three-dimensional parametric and visualization software for design of the cycloid gear hob are developed in VBA, a built-in customizing development tool of Auto CAD. A three-dimensional parametric model of cycloid gear hob can be created in Auto CAD after inputting related parameters. According to cutting process parameters, properties of cycloid gear hob cutter material, finite element analysis, obtaining stress, strain and displacement, is conducted in ANSYS. Its cutting capability is analyzed.
