Abstract

L'invention concerne un système d'entraînement d'une pompe (1) à carburant d'une turbomachine, la turbomachine comportant un axe moteur et un démarreur (16) ayant aussi fonction de générateur, le système comportant un réducteur (11) à train épicycloïdal comprenant trois éléments, un planétaire (11 A) central, une couronne (11 B) externe et un porte-satellites (11 U) dont les satellites (11 S) s'engrènent avec le planétaire et la couronne, un premier des trois éléments étant destiné à être relié à l'axe moteur (26) et un second des trois éléments étant destiné à être couplé à un arbre de la pompe (1), caractérisé en ce que lesdits trois éléments sont mobiles en rotation autour d'un axe du réducteur, en ce que le système comporte en outre le démarreur (12), ce dernier étant agencé pour entraîner en rotation le troisième desdits éléments du réducteur (11), de manière à modifier un rapport de vitesse de rotation entre le premier et le second desdits éléments. Elle concerne aussi la turbomachine équipée du système et le procédé de régulation de la pompe.The invention relates to a system for driving a fuel pump (1) of a turbomachine, the turbomachine comprising an engine shaft and a starter (16) also having the function of a generator, the system comprising a reduction gear (11) to epicyclic gear comprising three elements, a central sun gear (11 A), an outer ring gear (11 B) and a planet carrier (11 U) whose planet wheels (11 S) mesh with the sun gear and the ring gear, a first of the three elements being intended to be connected to the motor axis (26) and a second of the three elements being intended to be coupled to a pump shaft (1), characterized in that said three elements are movable in rotation around an axis of the reducer, in that the system further comprises the starter (12), the latter being arranged to drive the third of said elements of the reducer (11) in rotation, so as to modify a rotational speed ratio between the first and the second of said elements. It also relates to the turbomachine equipped with the system and the method for regulating the pump.
