摘　　要：随着CAD技术的不断成熟,应用CAD对机械零件进行三维造型越来越广泛,斜齿圆柱齿轮由于结构较复杂,在三维造型时需解决两个关键问题:一是绘制齿廓渐开线,二是创建斜齿圆柱齿轮的齿廓曲面。Auto CAD软件不仅具有强大的二维绘图功能,近年来三维绘图也得到了很大开发。本文描述了创建斜齿轮模型的思路和方法,并基于Auto CAD软件强大的二维绘图功能详细介绍了绘制斜齿轮齿廓渐开线的方法,避免了繁杂的数据计算;运用Auto CAD软件的"扫掠"命令实现了斜齿圆柱齿轮齿廓曲面的创建,解决了渐开线斜齿圆柱齿轮三维造型的两个关键问题。The idea and method of model creation for helical cylindrical gear have been described in the text The drawing method of helical gear tooth profile involute has been introduced in detail on the basis of powerful 2D drawing function from AutoCAD software, which avoids complex data calculation. The ＂scanning＂ command in AutoCAD software has been adopted to realize the creation of tooth profile surface for helical cylindrical gear. The two key problems during 3D modeling of involute helical cylindrical gear have been solved.
