摘　　要：根据短幅外摆线的形成机理,推导出一种新型滚子链轮。为了获得短幅外摆线链轮的性能,建立了短幅外摆线链轮的正时链传动模型,并进行了仿真分析。结果表明,采用短幅外摆线齿廓的凸轮轴链轮的角速度不均匀系数比GB1244-85标准链轮的降低了25.2%,比DIN8196标准链轮的降低了3.6%,短幅外摆线链轮能有效降低链轮的角速度波动,提高系统传动的平稳性。According to the forming mechanism of curtate epicycloid,a new roller chain sprocket is designed.In order to get the curate epicycloid performances of the new roller chain sprocket,the timing chain model is established and the simulation analysis is carried out.The results show that the angular velocity non-uniform coefficient of the new camshaft roller chain sprocket is reduced by 25.2% and 3.6% compared with GB1244-85 standard sprocket and DIN8196 sprocket respectively,the angular velocity fluctuation of curate epicycloid sprocket could be decreased effectively and the stability of chain transmission under high speed situation is improved.
