摘　　要：在阐述一种新型机构———双环式行星分度凸轮机构传动原理的基础上,分析了内齿板的摆动力。用广义质量替代法计算出应加的配重,从而解决了整机的摆动力和摆动力矩的平衡问题。样机的实验结果证明,通过配重平衡可以改善运动的平稳性。The paper presents the transmission principle of a new type of mechanism called double-ring planetary indexing cam and analyzes the shaking force of inner cam rings. With the method of general mass substitute, the counter-balance to be added is calculated, which solves the imbalance between shaking force and shaking moment of the double-ring planetary indexing cam mechanism. An experiment conducted on a sample mechanism shows that the counter-balance improves the motion stability of the mechanism.
