摘　　要：为解决渐开线齿轮的精确造型问题,提出了齿廓渐开线曲线的计算公式。基于 AutoCAD 的 ActiveX Automation 接口与 Visual Basic 编程语言,采用非均匀有理 B 样条拟合方法,实现了齿廓曲线的自动生成。在齿廓基础上,利用 AutoCAD 实体建模功能创建齿轮三维模型。该方法可以提高渐开线齿轮造型精度与效率,从而为渐开线齿轮的有限元分析提供了必要条件。To model involute gears accurately, a formula for calculating the involute curve of gear profile is presented. Based on AutoCAD ActiveX Automation and Visual Basic, auto-generation of gear profile is realized through B-spline fitting. On the basis of gear profile, three-dimensional model of involute gear can be established using solid modeling functions of AutoCAD. This approach can improve modeling precision and efficiency of producing involute gear, and provide necessary condition for finite element method analysis of involute gear.
