【摘要】 双凸轮用在冷镦机上。在已知主凸轮滚子中心轨迹后,用数学解析方法求出主凸轮和回凸轮型线的数学表达式,然后用该式在电子计算机上精确地求出凸轮型线。文中还求出了铣凸轮时铣刀中心的轨迹。对误差进行了分析。更多还原

【Abstract】 used in cold headers. On the basis of the given centred path of the main cam roller, the mathematical expressions of both the main and return cam profiles are derived by mathematical analytics, then the cam profile can be precisely calculated by computer. In addition, the centred path of the mill for milling the cam has been obtained in this paper,and the calculation error has been analysed as well.更多还原
