摘 要: 通过对封闭行星齿轮传动系统内部功率流的分析,研究了功率分配系数与系统内部功率流的关系,建立了功率分配系数与单元传动比的关系表达式以及效率计算公式,确定了无功率循环的必要条件。结合具体实例,绘制了功率流图谱及效率曲线,通过有功率循环系统与无功率循环系统的对比,指出合理地选择单元传动比,可避免系统内部出现功率循环,从而获得高效率的传动。为封闭行星齿轮传动系统的设计提供一种有效简洁的分析方法。 The relationship between partition coefficient of power and power flow in system is studied by analyzing closed planetary gear systems. The expression between power partition coefficient and the basic speed ratios is developed. The expression of efficiency is also proposed. The necessary conditions for power non-recirculation are determined. The graphic charts of speed ratios and efficiency are plotted based on examples given. Analyzing the graphic charts shows that can obtain the high efficiency transmission by selecting the basic speed ratios properly. A effective compact analysis processing method for design of closed planetary geared systems is offered.
