摘　　要：介绍了一种新型非圆齿轮副——心形非圆齿轮,从啮合传动特性出发分析了该非圆齿轮的运动规律,重点阐述了用三次曲线分段构造心形非圆齿轮节曲线,并列举工程实例验证该节曲线设计方法。通过Matlab计算作图,给出了心形非圆齿轮传动转角函数曲线、从动轮角速度变化曲线和角加速度变化曲线。计算作图的结果表明,该非圆齿轮的运动过程满足设计要求,角加速度变化曲线基本光滑,说明运动比较平稳,没有大的冲击。This paper introduces a new type of non-circular gear, heart-shaped non-circular gear, and analyzes the movement rule of a non-circular gear based on transmission characteristics. It fo-cuses on elaborating the method of using the cubic curve to construct neart-snapeo non-circular gear＇s pitch curve segmentally, and finally, this paper gives an engineering practical example to test the design method of pitch curve, and presents the transmission function curve of a heart- shaped non-circular gear transmission, the change curve of the follower angular velocity, and the change curve of the follower angular acceleration through the Matlab calculation drawing. The re- sults from Matlab calculation drawing indicate that the motion process of the non-circular gear satisfies the design requirements and that the change curve of angular velocity is basically smooth, whereby demonstrating that the motion is rather smooth without any large impact.
