双相外激波摆杆活齿传动耦合刚度
|
摘要
针对双相外激波摆杆活齿传动的结构特点,提出了活齿传动耦合刚度的概念。通过建立固定于活齿架的整体系统坐标系,分别推导出外激波凸轮与中心轮的齿形方程及传动压力角,综合应用变形协调条件与Palmgren形变公式,求解了多齿接触的系统径向力。在此基础上计算了传动系统的时变耦合刚度,并结合实例分析了主要结构参数对耦合刚度系数的影响。
Movable tooth coupling stiffness was proposed based on structures of double outer generator swing rod movable tooth transmission mechanisms.A coordinate fixed on movable tooth frame was established.Tooth profiles and pressure angles of double outer generator and central wheels were presented.System radial forces and time-varying coupling stiffnesses were investigated according to deformation compatibility conditions and Palmgren formula.The effects of structure parameters on coupling stiffness coefficients were analyzed.
