【摘要】 万向联轴器是用于传递不在同一轴线的两轴间的运动和动力的一种空间结构,针对目前市场的十字轴式万向联轴器不能满足特殊的复合加载工程应用,提出了一种异形虎克铰机构,该机构具有设计简单、安装方便和连接方式灵活等优点。重点对机构的自由度、运动特性进行了分析,并与普通十字轴式虎克铰进行对比,评价其优越性。利用ADAMS软件进行运动仿真分析,观察附加弯矩随被加载轴的转角变化情况,提出了选择最佳初始安装角度的方法,使复合加载时产生的附加弯矩取值最小。更多还原

【Abstract】 The universal joint is used to connect two offset shafts.As the cross-axis universal joint existing in the current market can not meet the particular compound loading for engineering application,a profiled universal joint is proposed,which has advantages of simple design,easy access to installment and flexible connection.The DOF and motion characteristics of the profiled universal joint are analyzed,and its advantages is evaluated comparing with the traditional cross-axis universal joint.Its motion is simulated in terms of ADAMS.Additional moment which is changed with the rotation of the shaft is observed.A method is proposed to select an optimal initial installation angle,which make the value of the additional moment minimized in the compound loading.更多还原
