Title (EN) TURBOCHARGER HAVING THRUST BEARING WITH BIASED OIL FLOW
(FR) TURBOCOMPRESSEUR AYANT UN PALIER DE BUTÉE AVEC ÉCOULEMENT D'HUILE POLARISÉ
Abstract:
(EN) A turbocharger (100) includes a turbine wheel (110), a compressor wheel (140), a shaft (160) coupled to the turbine wheel (110) and the compressor wheel (140), and a thrust bearing (186). The thrust bearing (186) includes a loaded side (182) and an unloaded side (282). The loaded side (182) bears a majority of axial loading caused by force imbalances between the turbine wheel (110) and the compressor wheel (140) during engine startup. The thrust bearing (186) restricts oil flow to the unloaded side (282) as compared to the loaded side (182) during engine startup.
(FR) L'invention concerne un turbocompresseur (100) comprenant une roue de turbine (110), une roue de compresseur (140), et un arbre (160) accouplé à la roue de turbine (110) et à la roue de compresseur (140), et un palier de butée (186). Le palier de butée (186) comprend un côté chargé (182) et un côté déchargé (282). Le côté chargé (182) porte une majorité de charge axiale provoquée par des déséquilibres de force entre la roue de turbine (110) et la roue de compresseur (140) pendant le démarrage du moteur. Le palier de butée (186) limite l'écoulement d'huile vers le côté déchargé (282) par rapport au côté chargé (182) pendant le démarrage du moteur.
