摘　　要：一种由轮系和凸轮机构组成的新型运动合成机构 ,把两个旋转运动合成一个有周向振动的旋转运动 ,能实现振幅和振频的调节 ;能够实现输出轴不同转速下的不同振动频率。凸轮采用了多齿的正弦曲线 ,高速性能好。本文介绍了该机构的工作原理 ,并分析了运动规律。The paper discusses that a new type of mechanism composed of planetary gears and cam can transform two rotating movements into one to realize the adjustments of the vibrations of amplitudes and frequencies.Thus, the frequencies of different vibrations under different rotating speeds of the output shaft can be realized. The cam is of several teeth of cosine curves and of good quality at high speed. It introduces the woking principles of this mechanism and analyzes the movement characteristics.
