SIGNAL FLOW GRAPH ANALYSIS METHOD FOR KINEMATIC CHARACTERISTICS OF SINGLE DEGREE OF FREEDOM PLANETARY GEAR TRAIN

依据行星齿轮系运动特性与原理,提出了一种用信号流图法计算复杂行星齿轮传动系统的特性参数。将信号流图的概念引入到单自由度行星齿轮系统的参数计算中,采用该法建立了XP系统、PX系统、T型混联系统、∏型混联系统和E型混联系统的信号流图模型。再利用信号流图的计算规则,获得了各种行星齿轮系的输入与输出及各传动构件的转速关系式,传动系统的转化传动比。该法直观性好,不仅可以做行星齿轮传动的可视化分析,也可以进行功率流的特性分析,为复杂行星齿轮系统运动特性参数计算等方面的研究提出了一种新的方法。

Based on features and the principles of department of planetary gear kinematic,this thesis proposes a signal flow graph method to calculate the characteristic parameters of the complex planetary gear transmission system. To introduce the concept of signal flow graph to the single degree of freedom in the parameter calculation of planetary gear system,and adopt the solution to establish the ＇XP＇system,＇PX＇system,T-type compound system,∏-type compound systems and E-type mixed signal flow graph model of the system. Reuse the calculation rules of signal flow graph,and got a variety of planetary gear train speed relation of input and output of the transmission components,the conversion ratio of the transmission system. The method was intuitive,This way can do visual analysis of planetary gear transmission,and can deal with the characteristics of power flow analysis,A new technique for the complex planetary gear kinematic system characteristic parameter calculation of the research was provided.
