Title (EN) SPEED REDUCTION GEARBOX WITH TWO INTERMEDIATE TRANSMISSION LINES
(FR) REDUCTEUR DE VITESSE A DEUX LIGNES INTERMEDIAIRES DE TRANSMISSION
Abstract:
(EN) Speed reduction gearbox with two intermediate transmission lines, particularly for a turbomachine, comprising an input line (12) and an output line driven by the input line via said intermediate lines, these intermediate lines being substantially parallel, characterized in that it comprises means for apportioning load between said intermediate lines, these load apportioning means comprising swivelling means (30) for rotational coupling of one end of the input line, and oil-based damping means (40, 50) for damping the radial movements of an opposite end of the input line.
(FR) Réducteur de vitesse à deux lignes intermédiaires de transmission, en particulier pour une turbomachine, comprenant une ligne d'entrée (12) et une ligne de sortie entraînée par la ligne d'entrée par l'intermédiaire desdites lignes intermédiaires, ces lignes intermédiaires étant sensiblement parallèles, caractérisé en ce qu'il comprend des moyens de répartition de charges entre lesdites lignes intermédiaires, ces moyens de répartition de charges comportant des moyens rotulants (30) d'accouplement en rotation d'une extrémité de la ligne d'entrée, et des moyens (40, 50) d'amortissement à huile des déplacements radiaux d'une extrémité opposée de la ligne d'entrée.
