Abstract

La présente invention concerne un train d’engrenages pour un moto-réducteur d’aéronef, le train d’engrenages comprenant :- une couronne (2) comprenant une denture intérieure (a1),- un arbre (30) s’étendant à l’intérieur de la couronne (2) le long d’une direction (D) et mobile en rotation par rapport à la couronne (2) autour de ladite direction, l’arbre (30) portant un premier pignon solaire (3a),- une pluralité de satellites (4) disposés radialement entre l’arbre (30) et la couronne (2), chaque satellite de la pluralité de satellites (4) étant configuré pour engrener avec la denture intérieure (a1) et avec le premier pignon solaire (3a),- un deuxième pignon solaire (5) mobile en rotation par rapport à la couronne (2) autour de ladite direction (D), chaque satellite de la pluralité de satellites (4) étant configuré pour engrener avec le deuxième pignon solaire (5). Figure pour l’abrégé : Fig. 2The present invention relates to a gear train for an aircraft geared motor, the gear train comprising:- a ring gear (2) comprising internal toothing (a1),- a shaft (30) extending at the inside the crown (2) along a direction (D) and rotatable relative to the crown (2) around said direction, the shaft (30) carrying a first sun gear (3a),- a plurality of planet gears (4) arranged radially between the shaft (30) and the ring gear (2), each planet gear of the plurality of planet gears (4) being configured to mesh with the internal toothing (a1) and with the first sun gear (3a), - a second sun gear (5) rotatable relative to the ring gear (2) around said direction (D), each satellite of the plurality of satellites (4) being configured to mesh with the second sun gear (5).
