Title
(EN) TURBOFAN ENGINE ASSEMBLY METHODS
(FR) PROCÉDÉS D'ASSEMBLAGE DE MOTEUR À DOUBLE FLUX
Abstract
(EN) A method for assembling a turbofan engine (20) comprises coupling a bearing assembly (176) and a shaft (420) as a unit to a bearing support (453). A transmission (46) and the fan shaft (132) are installed to a front frame assembly (172). The bearing assembly and shaft are installed as a unit so that the shaft engages a central gear (52) of the transmission and the bearing support engages the front frame assembly.
(FR) La présente invention se rapporte à un procédé permettant d'assembler un moteur à double flux (20), ledit procédé consistant à coupler un ensemble palier (176) et un arbre (420) sous la forme d'une seule unité à une chaise de palier (453). Une transmission (46) et l'arbre de ventilateur (132) sont agencés sur un ensemble cadre avant (172). L'ensemble palier et l'arbre sont installés sous la forme d'une seule unité de telle sorte que l'arbre vient en prise avec un engrenage central (52) de la transmission et que la chaise de palier vient en prise avec l'ensemble cadre avant.
