摘　　要：正交变传动比面齿轮传动是一种新型的齿轮传动形式.根据空间坐标变换关系及齿轮啮合原理,推导正交变传动比面齿轮副的节曲线、齿顶曲线、齿根曲线方程;结合加工刀具齿面方程与齿轮共轭基本原理,得到正交变传动比面齿轮的齿面参数方程;根据根切和变尖的条件,推导齿宽的计算方法;分析加工过程中刀具的空间走刀轨迹,基于VB和Solidworks(API)开发出正交变传动比面齿轮参数化设计和加工仿真系统;对正交变传动比面齿轮副进行实验研究,验证了理论推导过程和参数化设计及仿真加工方法的正确性和可行性.Orthogonal variable transmission ratio face gear drive is a new kind of gear transmission. The equation of the pitch curve, addendum curve and dedendum curve of face gear were established on the basis of spatial transformation relations and principles of gear. The parametric equation of tooth surface of the face gear was obtained by combining the parametric equation of cutter＇s tooth surface and conjugate tooth profiles theory. The calculation method of tooth width was derived on the basis of root cutting and tapering conditions. The space trajectory of the tool in the machining process was analyzed and the para- metric design and machining simulation system of orthogonal variable transmission ratio face gear were de- veloped on the basis of the environment of VB and Solidworks （API）. Finally, experimental study was carried out on the orthogonal variable transmission ratio face gear pair to verify the validity and feasibility of the theoretical derivation and parametric design and machining simulation of the variable transmission ratio face gear pair.
