Abstract | This semi-floating bearing (bearing) 13 comprises: an annular body 13a through which a shaft 15 is inserted and which extends in a direction crossing the vertical direction; a radial bearing surface 13d formed on the inner circumferential surface of the body 13a; and a plurality of oil supply grooves 39 which extend in the axial direction of the body 13a, are formed at intervals in the circumferential direction at positions on the radial bearing surface 13d other than the vertically lowermost section of the radial bearing surface, are disposed to be symmetrical with respect to a vertical axis V in a cross-section orthogonal to the axial direction of the radial bearing surface 13d, and have a circumferential gap widest on a vertically lower side.
La présente invention concerne un palier semi-flottant (un palier) (13) qui comprend : un corps annulaire (13a) à travers lequel est inséré un arbre (15) et qui s'étend dans une direction croisant la direction verticale; une surface de palier radial (13d) formée sur la surface circonférentielle interne du corps (13a); et une pluralité de rainures d'alimentation en huile (39) qui s'étendent dans la direction axiale du corps (13a), qui sont formées à des intervalles dans la direction circonférentielle à des positions sur la surface de palier radial (13d) autres que la section verticalement la plus basse de la surface de palier radial, qui sont disposées de sorte à être symétriques par rapport à un axe vertical (V) dans une section transversale orthogonale à la direction axiale de la surface de palier radial (13d), et qui présentent l'espace circonférentiel le plus large du côté verticalement inférieur.
セミフローティング軸受(軸受)13は、シャフト15が挿通され鉛直方向に対して交差する方向に延びる環状の本体13aと、本体13aの内周面に形成されるラジアル軸受面13dと、本体13aの軸方向に延在し、ラジアル軸受面13dのうち鉛直方向の最下部を除く位置に周方向に間隔を空けて形成され、ラジアル軸受面13dの軸方向に直交する断面において鉛直軸Vに対して線対称に配置され、周方向の間隔が鉛直下側において最も広くなっている複数の給油溝39と、を備える。 |
