摘　　要：采用空间力学方法,分析了十字轴万向节串联轴系在传动过程中各个万向节因惯性力而产生的附加扭矩。在考虑摩擦和惯性力的情况下,建立了十字轴万向节串联轴系的力学模型。分析了轴系中支撑距离、无支撑中间传动轴两端万向节距离、输入扭矩及轴间夹角等参数对轴系中最大支撑反力的影响,并对比分析了不同安装方式下各参数对最大支撑反力的影响。Using space mechanics analysis method, we analyze each cardan joint＇s additional torque caused by its inertial force in the transmission process of the shaft system with a series of cardan joints and establish the shaft system＇s mechanics model by taking its friction and inertial force into consideration. According to the mechanics mod- el, we discuss the effects of such parameters as distance of supports, distance of cardan joints at both ends of an intermediate transmission shaft without support, input torque and angle between shafts on the maximum support reaction of the shaft system and then contrast the effects of each parameter on the maximum support reaction when the shafts are installed in different ways.
