Abstract

Une portion d'extrémité (18) d'un vilebrequin (19) est logée dans un volume intérieur (12) d'un carter de moteur (10). Un palier (53) de guidage en rotation de la portion d'extrémité (18) du vilebrequin (19), supporté au moins partiellement par un siège de palier (14) délimitant une ouverture (15) du carter, comporte au moins une piste de guidage tournante (46) et une piste de guidage fixe (50). Un embout (22) traverse l'ouverture (15). L'embout (22) comporte une interface de contact et de fixation avec la portion d'extrémité (18) du vilebrequin (19) et une portée (46, 147) tournée radialement vers l'extérieur, la piste de guidage tournante (46) étant formée par la portée tournée radialement vers l'extérieur (46, 147) ou sur une bague intérieure de palier (146) frettée sur la portée tournée radialement vers l'extérieur (46, 147).An end portion (18) of a crankshaft (19) is housed in an interior volume (12) of an engine case (10). A bearing (53) for guiding the rotation of the end portion (18) of the crankshaft (19), supported at least partially by a bearing seat (14) delimiting an opening (15) of the housing, comprises at least one track rotating guide (46) and a fixed guide track (50). A tip (22) passes through the opening (15). The end piece (22) comprises a contact and fixing interface with the end portion (18) of the crankshaft (19) and a bearing surface (46, 147) facing radially outwards, the rotating guide track (46 ) being formed by the surface facing radially outwardly (46, 147) or on an inner bearing race (146) shrunk onto the surface facing radially outward (46, 147).
