Abstract:
(EN) The purpose of the invention is to reduce bearing loss due to lubricating oil. This invention comprises: a rotary shaft (14); a journal bearing (22) that is provided to the rotary shaft (14) and that rotatably supports the rotary shaft (14); a flange part (17b) having an opposing surface part (17bb) that is arranged so as to oppose a side surface part (22d) of the journal bearing (22) with a gap (D) therebetween in the axial direction in which the rotary shaft (14) extends; and a recess part (22e) provided in the side surface part (22d) or the opposing surface part (17bb). In the projected area of the journal bearing (22) in the axial direction, the area of a section including the recess part (22e) and not forming the gap (D) is larger than the area in which the side surface part (22d) and the opposing surface part (17bb) form the gap (D).
(FR) L'invention vise à réduire une perte de palier due à une huile lubrifiante. A cet effet, la présente invention comprend : un arbre rotatif (14) ; un palier de pivotement (22) qui est disposé sur l'arbre rotatif (14) et qui soutient en rotation l'arbre rotatif (14) ; une partie de bride (17b) ayant une partie de surface opposée (17bb) qui est agencée de façon à être opposée à une partie de surface latérale (22d) du palier de pivotement (22) avec un espace (D) entre ces dernières dans la direction axiale dans laquelle s'étend l'arbre rotatif (14) ; et une partie de creux (22e) dans la partie de surface latérale (22d) ou la partie de surface opposée (17bb). Dans la zone saillante du palier de pivotement (22) dans la direction axiale, la surface d'une zone comprenant la partie de creux (22e) et ne formant pas l'espace (D) est supérieure à la surface dans laquelle la partie de surface latérale (22d) et la partie de surface opposée (17bb) forment l'espace (D).
(JA) 潤滑油による軸受損失を低減すること。 回転軸(14)と、回転軸(14)に設けられて回転軸(14)を回転可能に支持するジャーナル軸受(22)と、回転軸(14)が延在する軸方向でジャーナル軸受(22)の側面部(22d)と間隔(D)をおいて対面して配置される対面部(17bb)を有するフランジ部(17b)と、側面部(22d)または対面部(17bb)に設けられた凹部(22e)と、を備え、ジャーナル軸受(22)の軸方向の投影面積において、側面部(22d)と対面部(17bb)とで間隔(D)をなす面積よりも、凹部(22e)を含んで間隔(D)をなさない部分の面積が大きい。
