摘　　要：齿轮是机械传动中不可或缺的零件,目前大部分的齿轮都采用渐开线齿廓。对如何绘制齿轮轮廓线、进而生成齿轮三维图形一直都是工程人员比较棘手的问题。文中基于AutoCAD软件平台,根据渐开线齿廓的形成特点及参数方程,详细介绍了二维渐开线齿轮的造型方法以及如何得到足够精确的渐开线齿轮轮廓,为后续设计奠定了基础。Gears are indispensable parts in mecllanical drive. At present, most gears adopt involute contour, so how to plot it and generating three-dimensional gear figures are intractable problems to the engineers. Based on AutoCAD platform, the forming character and their parametric equations of involute contours, the mouhling method of twodimensional gear involute contour and how to obtain accurate contours were introduced in detail in this paper, these works laid the foundation of subsequent designs.
