差动机构的运动与动力特性是设计和研究这类机构的首要问题。本文在[1]、[2]、[3]等论文的基础上,进一步运用基本行星机构的结构参数(i~0、i、v)来分析差动机构,将其运动和动力特性均表达为分支传动链特性的合成形式,从而使分支传动链的独立计算方法可以直接引入差动机构的计算中来,这不但深入揭示了它内在的合成规律,而且大大便利了推理的深入和运算的简化。本文分析了差动机构的转速及其波动率等运动特性;扭矩、功率、啮合功率以及动力特性的传递和转速反馈等动力特性。
The kinematics and dynamics of the differential mechanism are the primary issues in the design and study of such mechanisms. Based on the papers [1], [2], [3] and other papers, the differential mechanism is further analyzed using the structural parameters of the basic planetary mechanism (i ~ 0, i, v) Which is a composite form of the characteristics of the branch drive chain so that the independent calculation method of the branch drive chain can be directly introduced into the calculation of the differential mechanism. This not only reveals its intrinsic composition law in depth, but also greatly facilitates the inference and operation of the inference simplify. In this paper, the dynamic characteristics of differential mechanism such as rotation speed and its fluctuation rate are analyzed. The dynamic characteristics of torque, power, meshing power, transmission of dynamic characteristics and speed feedback are analyzed.
