The harmonic chain drive has a periodically varied theoretical chain length during its operation. This paper analyzes the changes in theoretical chain length when wave generator is at different positions, and indicates their effect on driven sprocket angular speed and transmission ratio. 谐波链传动在传动过程中所需链条的理论长度呈周期性变化,分析了传动中波发生器处在不同位置时链条理论长度的变化情况,并指出了这种变化对从动链轮角速度及传动比的影响。
