摘　　要：随着齿轮应用技术的发展,对齿轮精度提出了更高的要求,以实现齿轮传动高转速、高功率、低噪声和高传动精度的目标。采用滚刀加工齿轮的过程中,若忽略刀具的几何形状误差,滚刀安装误差就成为影响齿轮平稳性精度的主要因素之一。从滚刀安装误差出发,分析了滚刀安装误差对齿轮精度的影响,并依据范成法加工齿轮的原理,分别建立齿轮坐标系和刀具坐标系,利用坐标变换的方法推导出齿轮的齿廓方程,为齿轮三维参数化精确建模提供了设计基础。With the development of gear application technology,the higher requirements on gear precision are put forward,in order to achieve goals of high speed,high power,low noise and high transmission accuracy in gear transmission. In the gear hobbing process,if the tool geometry errors is ignored,the hob installation errors have become a major factor affecting the gear smooth precision. It starts from hob installation errors,the influence of hob installation errors on gear precision is analyzed. According to the principle of gear generating machining,the gear coordinate system and tool coordinate system are established,then by using the method of coordinate transformation,the gear tooth profile equation is deduced,which provides the design basis for 3D parametric gear precise modeling.
