Title (EN) MULTI-SEGMENT TURBOCHARGER BEARING HOUSING AND METHODS THEREFOR
(FR) LOGEMENT DE PALIER DE TURBOCOMPRESSEUR À SEGMENTS MULTIPLES ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) A turbocharger (102, 202, 302) including a rotating assembly (114, 214, 314) having a compressor wheel (120, 220, 320) and a turbine wheel (110, 210, 310) mounted on opposite ends of a shaft (112, 212, 312). A bearing housing (160, 260, 360) supports the rotating assembly (114, 214, 314) and comprises at least two segments (189, 190; 289, 290; 389, 390). Each segment (189, 190; 289, 290; 389, 390) has an opening large enough to radially receive the rotating assembly (114, 214, 314). The bearing housing segments (189, 190; 289, 290; 389, 390) are fastened (193) together and a flexible seal may be provided between the segments. The bearing housing (160, 260, 360) may house rolling element bearings (325) or journal bearings (149), for example. The bearing housing (160, 260, 360) is split axially (101, 201, 301) into an upper segment (189, 289, 389) and a lower segment (190, 290, 390). Alternatively, the bearing housing (160, 260, 360) is split axially (101, 201, 301) into a left segment and a right segment. The turbocharger (102) may further comprise an electric motor stator (148) disposed in the bearing housing (160). The bearing housing (160) may also include a defined passageway (143) extending around the stator (148) and configured to receive a cooling liquid.
(FR) L'invention concerne un turbocompresseur (102, 202, 302) comprenant un ensemble rotatif (114, 214, 314) ayant une roue de compresseur (120, 220, 320) et une roue de turbine (110, 210, 310) montées sur les extrémités opposées d'un arbre (112, 212, 312). Un logement de palier (160, 260, 360) supporte l'ensemble rotatif (114, 214, 314) et comprend au moins deux segments (189, 190 ; 289, 290 ; 389, 390). Chaque segment (189, 190 ; 289, 290 ; 389, 390) comporte une ouverture suffisamment large pour recevoir radialement l'ensemble rotatif (114, 214, 314). Les segments de logement de palier (189, 190 ; 289, 290 ; 389, 390) sont attachés (193) les uns aux autres, et un joint flexible peut être prévu entre les segments. Le logement de palier (160, 260, 360) peut loger des paliers d'élément de roulement (325) ou des paliers lisses (149), par exemple. Le logement de palier (160, 260, 360) est scindé axialement (101, 201, 301) en un segment supérieur (189, 289, 389) et un segment inférieur (190, 290, 390). En variante, le logement de palier (160, 260, 360) est scindé axialement (101, 201, 301) en un segment gauche et un segment droit. Le turbocompresseur (102) peut en outre comprendre un stator de moteur électrique (148) disposé dans le logement de palier (160). Le logement de palier (160) peut également comprendre un passage défini (143) s'étendant autour du stator (148) et configuré pour recevoir un liquide de refroidissement.
