摘要: 端曲面齿轮副是在非圆柱齿轮、非圆锥齿轮及面齿轮的基础上,提出的一种新型空间非圆齿轮传动机构。针对目前该齿轮副传动形式多样化,没有统一设计理论及方法的问题,通过引入圆柱滚子直动从动件圆柱端面凸轮副的运动关系,探讨了端曲面齿轮副的传动原理,建立了该齿轮副的传动比、移动速度和转速的通用化表达式。通过设定位移曲线,满足非圆齿轮节曲线设计要求,对传动比、齿顶和齿根曲线、轮齿分配、加工刀具最小齿数和齿宽等进行了设计。采用齿轮空间啮合原理,结合齿面方程和虚拟仿真技术,提出了一种端曲面齿轮副的通用化设计方法。重点分析了四种类型的端曲面齿轮副传动匹配模式、运动学特性及齿宽变化规律,统一了端曲面齿轮副的传动匹配模式。通过试验和检测验证了该设计方法的正确性。此设计方法可推广应用到任意位移曲线及任意偏心距的端曲面齿轮副,从而实现端曲面齿轮的通用化及参数化设计。

Abstract: Curve-face gear pair is a new type of spatial noncircular gear mechanism based on the noncircular gear, noncircular bevel gear and face gear. Aiming at the diversification of this gear pair transmission mode, which results in the lack of unified design theory and method, the transmission principles of curve-face gear are discussed by the motion rules of cylindrical end cam mechanism with reciprocating follower and cylindrical roller, and the general expressions of the transmission ratio, movement speed and rotational speed of the gear pair are established. The transmission ratio, addendum and dedendum curve, tooth distribution rule, minimum tooth number of cutting tool and maximum tooth width of curve-face gear are designed by setting the displacement rule of reciprocating follower. Based on the meshing theory, combined with the tooth surface equation and virtual simulation technology, a general design method for curve-face gear is proposed. The transmission patterns, kinematic characteristics and tooth width variation rules of four types of curve-face gear pairs are analyzed, and the related experiments are conducted to verify the correctness of the above design method. This design method can be applied to the arbitrary displacement curve and the arbitrary eccentric distance, and realize the general and parametric design of curve-face gear pair.

Key words: curve-face gear, design guideline, tooth profile, transmission model
