摘　　要：为了解决基于预设接触迹的面齿轮修形过程中程序实际可用性的问题,探究了沿齿宽方向修形方式相比于传统的法向修形除了具有编程可行性、运行效率高之外,是否会影响面齿轮接触区的分布情况.建立了面齿轮齿面方程;使用MATLAB分别编写了沿齿宽方向和法向进行修形的面齿轮修形齿面坐标生成程序,实现了修形后面齿轮的可视化,并用CATIA进行了三维建模;最后应用ABAQUS进行了2种修形方式的齿面接触分析,得到了面齿轮与小齿轮的分析仿真结果.由结果可知,齿宽方向修形方式可以得到更宽的接触区范围,但法向修形的接触区整体分布更靠近齿根,更符合面齿轮的力学特性,因此,在面齿轮强度足够的情况下,可以采用齿宽方向修形的方式替代法向修形的方式,这样会有利于后续进一步编写研究传动误差的程序.In order to solve actual usability problems of programs used in the modification process of face gear based on preset contact trace,this paper has explored whether modification in tooth width direction has different effects compared with modification in the normal direction which has the advantages of programming feasibility and high operation efficiency.The equation of tooth of face gear was established in this paper;MATLAB was used to finish the program of the modification in tooth width direction and normal direction respectively.The visual surface picture of modification was accomplished and CATIA was used to build the 3D models.At last,ABAQUS was used to simulate the tooth contact analysis of the two ways and the simulation results was analyzed.The result shows that modification in tooth width direction can get a wider contact area;but the contact region of modification in normal direction distributes closer to the root of face gear,more in line with the mechanical characteristics of the face gear.Therefore,if the strength of face gear is enough,modification in tooth width direction can be used to replace modification in normal direction,which will be beneficial to the further programming of the transmission error study
