摘　　要：根据齿轮啮合原理及变齿厚斜齿轮的加工原理,由产形齿条的齿面方程,推导了变齿厚斜齿轮渐开螺旋面、过渡曲面及齿根面的齿面方程;用Matlab编程生成了变齿厚斜齿轮完整、精确的齿面;由生成齿面上点的三维坐标值,建立了变齿厚斜齿轮的精确实体模型。这一齿面生成的方法具有一定的通用性,可以方便地生成圆柱直齿轮、斜齿轮以及变齿厚直齿轮的精确齿面。According to the space meshing principles and processing principle of helical beveloid gear,the tooth face equations of the working tooth surface,the fillet surface and the tooth root surface of helical beveloid gear is derived by means of the tooth face equations of the virtul rack.The complete and precise tooth surface of helical beveloid gear is generated by using Matlab.The precise solid model of helical beveloid gear is estaldished by three-dimensional coordinates of points on the generated tooth surfaces.The tooth surface generation method is generic and it can easily generated the tooth surface of spur gear,helical gear and straight beveloid gear accurately.
