摘　　要：从理论上分析了直齿圆锥齿轮的齿廓形状,结合具体实例,以UG NX 4.0为平台,利用其功能强大的表达式工具和三维建模模块,介绍了绘制锥齿轮大端齿槽曲线的方法,模仿齿轮的实际加工,在锥齿轮的背锥上去除齿槽,得到了直齿内圆锥齿轮的三维参数化模型,并对其参数化控制方法进行了简述,为后续直齿内圆锥齿轮的数控加工、虚拟装配等奠定基础。The contour shape of straight bevel gear is analyzed theoretically. With an example, a method is discussed to draw outer-slot curve of straight bevel gear by using the function of expression and modeling in UG NX 4.0. Imitating the process of practical gear machining, a 3D parameterized model of straight internal bevel gear is obtained by slotting from the back cone, which is helpful to NC machining and virtual assembly of the gear.
