Abstract:
(EN) This turbocharger (1) is provided with: a rotating shaft (4); a turbine wheel (2); a compressor wheel (3); a rolling bearing (5) that rotatably supports the rotating shaft (4) around an axis (C) and that comprises an inner race (50) fixed to the outer circumferential surface of the rotating shaft (4), an outer race (51) surrounding the inner race (50) from the outside in the radial direction, and rolling bodies (52) arranged between the inner race (50) and the outer race (51); a housing (6) that covers the rolling bearing (5) from the outer circumferential side with a gap (S) between said housing (6) and the outer circumferential surface of the rolling bearing (5); and a lubricating oil supply line (72) that supplies lubricating oil within the housing (6). The turbocharger (1) is additionally provided with an operating state detection unit (76) that detects the operating state of the turbocharger (1) and a lubricating oil adjustment unit (75) that changes the flow rate of lubricating oil flowing through the lubricating oil supply line (72) in accordance with the operating state.
(FR) L'invention concerne un turbocompresseur (1), lequel turbocompresseur comporte : un arbre rotatif (4) ; une roue de turbine (2) ; une roue de compresseur (3) ; un palier de roulement (5) qui porte de façon rotative l'arbre rotatif (4) autour d'un axe (C) et qui comprend une piste interne (50) fixée à la surface périphérique externe de l'arbre rotatif (4), une piste externe (51) entourant la piste interne (50) à partir de l'extérieur dans la direction radiale, et des corps de roulement (52) disposés entre la piste interne (50) et la piste externe (51) ; un boîtier (6) qui recouvre le palier de roulement (5) à partir du côté périphérique externe avec un espace (S) entre ledit boîtier (6) et la surface périphérique externe du palier de roulement (5) ; et une ligne de fourniture d'huile de lubrification (72) qui fournit de l'huile de lubrification à l'intérieur du boîtier (6). Le turbocompresseur (1) comporte de plus une unité de détection d'état de fonctionnement (76) qui détecte l'état de fonctionnement du turbocompresseur (1) et une unité de réglage d'huile de lubrification (75) qui change le débit d'écoulement de l'huile de lubrification s'écoulant à travers la ligne de fourniture d'huile de lubrification (72) en fonction de l'état de fonctionnement.
(JA) このターボチャージャ(1)は、回転軸(4)と、タービンホイール(2)と、コンプレッサホイール(3)と、回転軸(4)の外周面に固定された内輪(50)、内輪(50)を径方向外側から囲う外輪(51)、及び、内輪(50)と外輪(51)との間に配置された転動体(52)を有し、回転軸(4)を軸線(C)回りに回転可能に支持する転がり軸受(5)と、転がり軸受(5)を、転がり軸受(5)の外周面との間に隙間(S)を介して外周側から覆うハウジング(6)と、ハウジング(6)内に潤滑油を供給する潤滑油供給ライン(72)と、を備えるターボチャージャ(1)であって、ターボチャージャ(1)の運転状態を検出する運転状態検出部(76)と、運転状態に応じ、前記潤滑油供給ライン(72)を流通する潤滑油の流量を変化させる潤滑油調整部(75)と、を備える。
