摘　　要：基于人字齿轮传动的特点和面齿轮传动的原理,提出了面齿轮人字齿的构建方法,为了使得不同旋向的轮齿均获得局部接触特性,采用了齿向俢形以实现接触路径的偏移;为在最大限度上利用面齿轮人字齿的齿宽,提出了面齿轮无退刀槽人字齿的加工方法,设计了其使用的刀具;阐述了面齿轮人字齿的加工原理,建立了坐标系,并推导了面齿轮人字齿面的数学模型和齿面几何啮合性能仿真模型;最后给出了面齿轮人字齿面的计算结果,并绘制了虚拟样机,并完成了齿面接触分析。结果表明:人字齿面齿轮圆柱齿轮的啮合具有理想的啮合性能,可以满足啮合传动的需要。Based on the property of double-helical gear driver and the principle of the face gear driver, the method for constructing the double-helical tooth of the face gear was presented; in order to obtain local bearing contact for teeth with different screw directions, longitudinal tooth modification was applied to realize shifting contact path. Then, for the sake of using the maximum tooth width of the face gear with double-helical pinion, the manufacturing method and the cutter for the herringbone tooth of the face gear were designed. Third, the generation principle for the herringbone tooth of the face gear without tool withdrawal groove was elaborated; and the applied coordinate system, tooth surface mathematical model of the herringbone tooth of the face gear, simulation model of the tooth surface contact performance were established to make the face gear have the maximum tooth width. Finally, the calculation result of the herringbone tooth surface of the face gear was given and the virtual prototype was drawn, and the tooth surface contact analysis was completed. The result demonstrates that the double-helical face gear driver has desired meshing performance, which could meets the needs of the meshing transmission.
