closed planetary gear train

基本解釋

The closed planetary gear train, owing to its compactness in structure and seperation in power flow, has been widely applied in many machines, especially in flyer.
封閉式行星輪系，由于具有結(jié)構(gòu)緊湊、功率分流等特點(diǎn)，在各種機(jī)械，特別是飛行器中，得到了廣泛的應(yīng)用。
About the problem how to calculate efficiency of differential gear train, in this paper, there is a new idea of"extending a differential gear train to an equivalent closed planetary gear train".
本文就如何計(jì)算差動(dòng)輪系效率的問題，提出將差動(dòng)輪系擴(kuò)展成為等效封閉式行星輪系再進(jìn)行計(jì)算的思想。
