摘要: 为更简单清晰地对封闭式行星轮系的功率流情况进行判别,利用键合图能量守恒和功率流动的特点,将键合图理论应用于该类轮系的功率流分析中.以功率汇流型、回流型2种形式的封闭式行星轮系为例,根据轮系的传动关系,利用绝对速度法建立轮系的键合图模型,根据提出的功率流向判别依据对轮系进行功率流向判别,得到整个轮系及其转换机构的功率流情况,为轮系的效率计算提供了基础.该方法适用于其它复杂轮系的功率流判别中,比传统方法更具直观性、系统性.

Abstract: In order to distinguish the power flow of the closed planetary gear train more simply and clearly, the theory of bond graph was applied for the analysis of power flow of the gear train utilizing the characteristic of conversation of energy and power fluxion of bond graph. Taking the power regurgitant and confluence style of the gear trains for examples, the bond graph model of the gear trains was established according to the transmission relationships and the method of absolute speed. And then the power flow of the gear trains, as well as the conversion mechanism, was got after distinguishing the power flow basing on the discriminant, which provides the foundation for the efficiency computing. This method which is more intuitionistic and systematic than the traditional methods could be applied in the power flow judgement of other complex gear trains.
