Abstract
(EN)
Provided is an electric turbo-machine comprising: a housing; a rotating shaft rotatably supported by the housing through a rolling bearing; an impeller; and an electric motor. The housing has an oil supply section to which lubricating oil is supplied. A tubular oil supply member is mounted to the oil supply section. The oil supply member has: a supply passage extending within the oil supply member in the axial direction of the oil supply member and in communication at a first end of the oil supply member with the oil supply section; and an ejection hole in communication with the supply passage and configured so as to eject lubricating oil toward a portion between the inner ring and outer ring of the rolling bearing.

L'invention concerne une turbomachine électrique comprenant : une enveloppe ; un arbre tournant supporté de manière rotative par l'enveloppe au moyen d'un roulement ; une roue à aubes ; et un moteur électrique. L'enveloppe comporte une section d'alimentation en huile approvisionnée en huile lubrifiante. Un élément tubulaire d'alimentation en huile est monté sur la section d'alimentation en huile. L'élément d'alimentation en huile comporte : un passage d'alimentation s'étendant à l'intérieur de l'élément d'alimentation en huile dans la direction axiale de l'élément d'alimentation en huile et en communication, au niveau d'une première extrémité de l'élément d'alimentation en huile, avec la section d'alimentation en huile ; et un trou d'éjection en communication avec le passage d'alimentation et conçu pour éjecter de l'huile lubrifiante vers une partie entre l'anneau interne et l'anneau externe du roulement.
