    同時以降低高速傳動過程中(zhōng)鏈條的波動量和鏈條與鏈輪的齧合沖擊力及提高從動輪運轉的平穩性爲基本原則,進行了新型滾子鏈鏈輪齒形的研究。以滾子在齒根圓上作純滾動爲前提,得出了新型鏈輪的外(wài)擺線方程；利用包絡線求等距線的方法,推導出了新型鏈輪的齒廓方程；參照國标鏈輪的設計,得到了外(wài)擺等距線鏈輪的設計方法。
    其次,基于三維建模技術建立了GB1244-85标準鏈輪、日本JIS B 1801-90标準鏈輪、外(wài)擺等距線鏈輪及與它們相配套的傳統滾子鏈傳動模型。通過在ADAMS中(zhōng)添加旋轉副、驅動力等約束,建立了以上三種滾子傳動系統的多剛體(tǐ)系統動力學模型。完成了主動鏈輪轉速爲1000-8000r／min時的仿真實驗,并從理論上提出了修正新型鏈輪齒形的方法。
    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.
