Power transmitted through a particular branch in mechanisms comprising planetary gear trains and other fixed or variable transmissions

摘要

In this article, a methodology to obtain an expression of the power transmitted through a mechanism containing various axles, connected among them with planetary, fixed and variable-speed-ratio gear trains, is presented. The results demonstrate that it is possible to find an equation for the power circulating through a branch, in this case with variable speed ratio capabilities, by making use only of kinematical considerations. The article explains the foundations of the methodology and provides examples to illustrate the easiness of implementation. El present treball presenta una metodologia per trobar la potencia transmesa a traves d'una transmissio continguda en un mecanisme complex composat per multiples eixos connectats entre ells per trens epicicloidals i relacions de transmissio fixes i variables. Es demostra que es possible trobar una equacio de la potencia transmesa a traves d'una branca, en aquest cas amb capacitat de variar la seva relacio de transmissio, nomes a partir de consideracions cinematiques. Es presenten els fonaments del metode i es presenten eixamples per demostra la facilitat de la seva aplicacio.
