(EN) POWER GENERATING DEVICE FOR AIRCRAFT
(FR) DISPOSITIF DE GÉNÉRATION DE PUISSANCE POUR AÉRONEF
Abstract
(EN)
An electric power generating device for an aircraft, which is driven by an output of an aircraft engine, comprises an input shaft to which a driving force of the engine is transmitted; a transmission arranged with the input shaft; an electric power generator arranged with the input shaft and the transmission and driven by an output of the transmission; a driving force transmission mechanism disposed on a first end side of the input shaft in an axial direction thereof, the driving force transmission mechanism being configured to transmit the output from the transmission to the electric power generator; and a casing including a mounting section on the first end side of the input shaft in the axial direction, wherein the transmission includes an input section provided on a second end side of the input shaft in the axial direction, the input section being configured to receive as an input a rotational driving force from the input shaft, and an output section provided on the first end side of the input shaft in the axial direction, the output section being configured to output to the driving force transmission mechanism the rotational driving force whose speed has been changed, and wherein the driving force transmission mechanism has an inner space and the input shaft is inserted into the inner space.

(FR)
L'invention concerne un dispositif de génération de puissance pour aéronef, qui comprend : un arbre d'entrée par lequel la force d'entraînement du moteur est transmise ; une transmission qui est agencée en parallèle avec l'arbre d'entrée ; un générateur qui est agencé en parallèle avec l'arbre d'entrée et la transmission, et est entraîné par la sortie de la transmission ; un mécanisme de transmission de puissance qui est disposé sur un premier côté d'extrémité, dans la direction axiale, de l'arbre d'entrée et transmet la sortie de la transmission au générateur ; et un boîtier qui a une partie de montage sur le premier côté d'extrémité, dans la direction axiale, de l'arbre d'entrée. La transmission comprend : une unité d'entrée dans laquelle est entrée la force d'entraînement en rotation de l'arbre d'entrée, ladite unité d'entrée étant située sur l'autre côté d'extrémité, dans la direction axiale, de l'arbre d'entrée ; et une unité de sortie qui fournit la force d'entraînement en rotation à changement de vitesse au mécanisme de transmission de puissance, ladite unité de sortie étant située sur le premier côté d'extrémité, dans la direction axiale, de l'arbre d'entrée. Le mécanisme de transmission de puissance a un espace interne dans lequel l'arbre d'entrée est inséré.
