摘　　要：为了进一步研究变双曲圆弧齿线圆柱齿轮的啮合及传动特点,以变双曲圆弧齿线圆柱齿轮作为研究对象,通过对其成型理论的分析,得到了齿面方程、齿根过渡曲面方程,利用数值仿真软件得到工作齿面和过渡齿面的齿面点云;根据得到的点云文件,结合三维辅助设计软件实现变双曲圆弧齿线圆柱齿轮的精确建模;进行数字滚检实验方法检查模型的接触区域。将建好的精确模型利用桌面级3D打印机打印出来,验证利用精确模型进行试件加工的可行性。为变双曲圆弧齿线圆柱齿轮后续有限元研究和专用机床设计及理论研究提供了可靠的理论基础。In order to further study the meshing and transmission characteristics of cylindrical gear with variable hyperbolic circular-arc-tooth-trace(VH-CATT), VHCATT was taken as the research object. According to the point cloud files obtained, the accurate modeling of VHCATT is realized with the aid of 3d design software. The digital rolling test method is used to check the contact area of the model. The precision model is printed out with desktop 3D printer to verify the feasibility of sample machining with precision model. It provides a reliable theoretical basis for the follow-up finite element analysis of VHCATT and the design and theoretical study of special machine tools.
