摘要: 结合齿轮啮合定理,给出了实现预期传动特性函数的端曲面齿轮副节曲线和齿形的通用设计方法,以满足不同应用需求.基于端曲面齿轮副的复杂运动形式和应用场合,根据空间坐标变换理论,推导出端曲面齿轮副传动比、轴向移动速度,建立齿面滑移速度方程,并针对各轮齿及其齿面参数进行分析,讨论了端曲面齿轮副齿面滑移特性及其影响因素.结果表明,端曲面齿轮齿面滑移速度的大小和方向随着齿高的变化而变化,且在半个转动周期内,各齿的滑移特性各不相同.

Abstract: According to the gear meshing theorem, the ordinal design of the pitch curve and tooth surface of the gear pair is presented to realize the predicted transmission function for different application. Based on the complex motion and applications of curve face gear, the transmission ratio and axial movement speed are proposed by space coordinate transformation, also the slip velocity equation on the tooth surface curve face gear is established. The sliding characteristics on the tooth surface with different parameters are given. The results show that the size and direction of sliding velocity vary with the tooth height, and the sliding characteristics of the 5 teeth are different during the half cycle.

Key words: curve face gear pair, compound motion, surface sliding, function reproduction, tooth surface equation
