Abstract

L’invention concerne un module de lubrification (23) pour une turbomachine comprenant une soufflante (16) et un réducteur (20) qui assure une démultiplication de vitesse de rotation de la soufflante (16), ce module de lubrification (23) comprenant une pompe (22) à piston (24) qui est configurée pour renouveler un lubrifiant au niveau du réducteur (20) par translation alternative de son piston (24), et un mécanisme d’entraînement (23) de la pompe (22) adapté pour prélever un mouvement de rotation sur un organe tournant de la turbomachine, et convertir ce mouvement de rotation en un mouvement de translation alternative du piston (24) de la pompe (22).
