    同时以降低高速传动过程中链条的波动量和链条与链轮的啮合冲击力及提高从动轮运转的平稳性为基本原则,进行了新型滚子链链轮齿形的研究。以滚子在齿根圆上作纯滚动为前提,得出了新型链轮的外摆线方程；利用包络线求等距线的方法,推导出了新型链轮的齿廓方程；参照国标链轮的设计,得到了外摆等距线链轮的设计方法。
    其次,基于三维建模技术建立了GB1244-85标准链轮、日本JIS B 1801-90标准链轮、外摆等距线链轮及与它们相配套的传统滚子链传动模型。通过在ADAMS中添加旋转副、驱动力等约束,建立了以上三种滚子传动系统的多刚体系统动力学模型。完成了主动链轮转速为1000-8000r／min时的仿真实验,并从理论上提出了修正新型链轮齿形的方法。
    Fluctuations in the amount of chain in the process of reducing high-speed transmissionchainsprocket meshing impactimprove the smoothness of the driven wheel operation as the basic principle of a new roller chain sprocket tooth. Pure rolling of the roller on the root circle as the premise, reached a new sprocket epicycloid equation; envelope seek equidistance line method to deduce the new sprocket tooth profile equation; reference to the GB the design of the sprocket outside placed equidistance line sprocket.
    Secondly, based on three-dimensional modeling techniques GB1244-85 standard sprocket, Japan JIS B 1801-90 standard sprocket, placed outside the equidistance line sprocketmatching with their traditional roller chain drive models. ADAMS rotary vice, the driving force constraints, more than three roller transmission of multibody dynamics model.
