Title (EN) FLOATING BUSH BEARING AND SHIP EXHAUST TURBINE
(FR) PALIER À DOUILLE FLOTTANT ET TURBINE D’ÉCHAPPEMENT DE NAVIRE
(JA) 浮動ブシュ軸受及び舶用排気タービン
Abstract:
(EN) A ship exhaust turbine 7, which is to be installed in a ship together with a ship engine 5, comprises: a turbine part 71 that is rotated by an exhaust gas supplied from the ship engine 5; a shaft 3 that rotates in an integral manner with the turbine part 71; and a floating bush bearing 2 that supports the shaft. The floating bush bearing 2 comprises: a bearing housing 21; a bush 4 that is accommodated in the bearing housing 21 so as to be unable to rotate and that is fitted to the outside of the shaft 3; and an oil film that is formed of a lubricating oil on an inner circumferential surface 42 side and an outer circumferential surface 41 side of the bush 4. The bush 4 includes: at least one oil supply hole 43 that penetrates through the bush 4 in a radial direction; and a partial circumferential groove 44, which is formed in an upper half of the inner circumferential surface 42 of the bush 4 and the depth of which decreases in a rotational direction of the shaft 3.
(FR) L'invention concerne une turbine (7) d'échappement de navire, qui doit être installée dans un navire conjointement avec un moteur (5) de navire, et comprend : une partie turbine (71) entraînée en rotation par un gaz d'échappement alimenté par le moteur (5) de navire ; un arbre (3) qui tourne d'un seul tenant avec la partie turbine (71) ; et un palier à douille flottant (2) qui supporte l'arbre. Le palier à douille flottant (2) comprend : un logement (21) de palier ; une douille (4) logée dans le logement (21) de palier de façon à ne pas pouvoir tourner et ajustée sur l'extérieur de l'arbre (3) ; et un film d'huile qui est formé d'une huile de lubrification sur un côté surface circonférentielle interne (42) et un côté surface circonférentielle externe (41) de la douille (4). La douille (4) comprend : au moins un trou (43) d'alimentation en huile qui pénètre à travers la douille (4) dans une direction radiale ; et une rainure circonférentielle partielle (44) formée dans une moitié supérieure de la surface circonférentielle interne (42) de la douille (4) et dont la profondeur diminue dans une direction de rotation de l'arbre (3).
(JA) 舶用エンジン5と共に船舶に搭載される舶用排気タービン7が、舶用エンジン5から供給された排気ガスによって回転するタービン部71と、タービン部71と一体的に回転する軸3と、軸を支承する浮動ブシュ軸受2とを備える。浮動ブシュ軸受2が、軸受ハウジング21と、軸受ハウジング21に回転不能に内装されると共に軸3に外嵌されたブシュ4と、ブシュ4の内周面42側と外周面41側のそれぞれにおいて潤滑油により形成された油膜とを備える。ブシュ4は、ブシュ4を半径方向に貫く少なくとも1つの給油孔43と、ブシュ4の上半分の内周面42に形成された軸3の回転方向に深さが浅くなる部分円周溝44とを有する。
