摘　　要：内啮合珩齿是一种齿轮精密加工的工艺方法,由于其斜齿内珩轮与直齿圆柱齿轮属于交错轴齿轮副,齿面之间存在着微量的干涉。通过去除干涉量可得到鼓形齿,而鼓形齿对于降低噪声,增强齿轮传动的平稳性都有极大的益处。由于交错轴齿轮副的啮合情况非常复杂,轮齿之间的干涉量解析计算也难以实现。为此利用三维建模软件UG/NX实现了对圆柱内斜齿轮和直齿圆柱齿轮参数建模和装配,通过模拟齿轮的啮合运动,成功将干涉部分切除加工出鼓形齿。最终得到单个齿上的干涉量。Internal gear honing is a process of precise machining of the gear, in the process, there exists trace amounts of interference between tooth surfaces as helical internal honing wheel and spur gear are a gear pair with crossed shaft, a crown teeth can be obtained by removing the interference amount, and the crown teeth brings great ben- efit for reducing noise and enhancing the stability of transmission of the gear. Because the meshing of a crossed shaft gear pair is very complex, the analytical calculation of the quantity of interference between teeth is also difficult to be achieved. By using a 3 - D modeling software UG/NX, the parameter of the cylindrical internal helical gear and the spur gear modeling and assembly simulation is realized, through the simulation of gear meshing movement, interference is successfully removed to process the crown teeth, and finally data of interference for a single tooth is obtained.
