Abstract
La présente invention concerne un support de palier configuré pour supporter un palier d’une turbomachine, la turbomachine présentant un axe longitudinal et comprenant un couvercle d’arrivée d’huile, le support de palier étant configuré pour s’étendre autour de l’axe longitudinal et comprenant :une paroi intérieure radiale configurée pour délimiter avec le couvercle d’arrivée d’huile une enceinte (E) entourant le palier, une paroi extérieure radiale écartée radialement de la paroi intérieure radiale, les sens intérieur et extérieur étant repérés par rapport à l’axe longitudinal de la turbomachine,l’une des deux dites parois comprenant une portion concave définissant une cavité de récupération d’huile (23) en amont de l’enceinte,le support de palier comprenant un conduit de passage d’huile (15) configuré pour mettre en communication de fluide l’enceinte (E) et la cavité de récupération d’huile (23), le conduit de passage d’huile étant positionné radialement entre la paroi intérieure radiale et la paroi extérieure radiale. L’invention concerne également un ensemble comprenant un tel support de palier et une bague externe de palier fixée sur la paroi intérieure radiale du support de palier. Figure pour l’abrégé : F ig ure . 3 bThe present invention relates to a bearing support configured to support a bearing of a turbomachine, the turbomachine having a longitudinal axis and comprising an oil inlet cover, the bearing support being configured to extend around the axis longitudinal and comprising:a radial inner wall configured to delimit with the oil inlet cover an enclosure (E) surrounding the bearing, a radial outer wall spaced radially from the radial inner wall, the inner and outer directions being marked relative to the longitudinal axis of the turbomachine, one of the two said walls comprising a concave portion defining an oil recovery cavity (23) upstream of the enclosure, the bearing support comprising an oil passage duct (15) configured to place the enclosure (E) and the oil recovery cavity (23) in fluid communication, the oil passage duct being positioned radially between the radial inner wall and the radial outer wall. The invention also relates to an assembly comprising such a bearing support and an outer bearing ring fixed to the radial inner wall of the bearing support. Figure for the abstract: F ig ure . 3 b
