Title (EN) JOURNAL BEARING AND ROTARY MACHINE
(FR) PALIER LISSE ET MACHINE ROTATIVE
(JA) ジャーナル軸受および回転機械
Abstract:
(EN) A journal bearing that comprises: a carrier ring; a plurality of bearing pads that are provided on the inner circumferential side of a lower half region of the carrier ring and that are configured to support a rotor shaft from below; a pair of side plates that are provided on both sides of the plurality of bearing pads with respect to the axial direction of the rotor shaft; and a dam that is provided on the inner circumferential side of the carrier ring at a downstream-side portion of an upper half region of the carrier ring and that is configured to suppress the flow of carryover oil to the downstream side. A gap that allows a bearing interior space that is surrounded by the pair of side plates to communicate with the outside is provided between an inner circumferential surface of each side plate and an outer circumferential surface of the rotor shaft.
(FR) L'invention concerne un palier lisse qui comprend : un anneau de support; une pluralité de coussinets de palier qui sont disposés sur le côté circonférentiel interne d'une demi-région inférieure de l'anneau de support et qui sont conçus pour soutenir un arbre de rotor par le dessous; une paire de plaques latérales qui sont disposées des deux côtés de la pluralité de coussinets de palier par rapport à la direction axiale de l'arbre de rotor; et un élément de retenue qui est disposé sur le côté circonférentiel interne de l'anneau de support au niveau d'une partie côté aval d'une demi-région supérieure de l'anneau de support et qui est conçu pour bloquer l'écoulement d'huile d'entraînement vers le côté aval. Un espace, qui permet à un espace intérieur de palier qui est entouré par la paire de plaques latérales de communiquer avec l'extérieur, est formé entre une surface circonférentielle interne de chaque plaque latérale et une surface circonférentielle externe de l'arbre de rotor.
(JA) ジャーナル軸受は、キャリアリングと、前記キャリアリングの下半領域の内周側に設けられ、ロータ軸を下方から支持するように構成された複数の軸受パッドと、前記ロータ軸の軸方向における前記複数の軸受パッドの両側に設けられた一対のサイドプレートと、前記キャリアリングの上半領域のうち下流側の部分において前記キャリアリングの内周側に設けられ、キャリーオーバ油の下流側への流れを抑制するように構成されたダムと、備え、各々の前記サイドプレートの内周面と前記ロータ軸の外周面との間に前記一対のサイドプレートによって囲まれた軸受内部空間と外部とを連通させるための隙間が設けられている。
