摘　　要：为满足从动齿轮运动学特性要求,提出了一种匀变非圆齿轮设计方法。基于匀变非圆齿轮的概念,在速度曲线和加速度曲线的基础上,推导了节曲线方程,建立了齿轮截面长度和中心距的计算模型。以Ⅰ型匀变非圆齿轮为例,提出了匀变非圆齿轮传动的设计方法。利用Adams软件模拟分析了从动齿轮的角速度和角加速度曲线的形状,验证了设计方案的有效性;分析了匀变非圆齿轮传动装置的压力角、根切和啮合系数等特性。结果表明,所提出的设计方法通过改变给定速度曲线和加速度曲线的参数,能够实现节曲线形状的灵活控制。In order to meet the requirements of kinematic characteristics of driven gear,a design method of uniform non-circular gear is proposed.Based on the concept of uniform non-circular gear,the pitch curve equation is derived on the basis of velocity curve and acceleration curve,and the calculation model of gear sec⁃tion length and center distance is established.Taking type I uniform non-circular gear as an example,the design method of uniform non-circular gear transmission is proposed.The shape of angular velocity and angular accel⁃eration curve of driven gear is simulated and analyzed by using Adams software,and the effectiveness of the de⁃sign scheme is verified.The characteristics of pressure angle,undercutting and meshing coefficient are ana⁃lyzed.The results show that,the proposed design method can realize the flexible control of pitch curve shape by changing the parameters of given speed curve and acceleration curve.
