Title (EN) DAMPER STRUCTURE AND ROTATING MACHINE
(FR) STRUCTURE D'AMORTISSEMENT ET MACHINE ROTATIVE
(JA) ダンパー構造及び回転機械
Abstract:
(EN) Disclosed is a damper structure equipped with: a sleeve (11) which is provided on an axial end part (3a) extending outward of a bearing which supports an axle (3), and is provided on the outer circumference of the axial end part (3a); a housing (12) which is provided in the radial direction of the sleeve (11) and the axle (3), leaving an interval; and a moving part (13) which relatively moves the housing (12) and the sleeve (11) in the axial direction. In addition, a squeeze film (S (S1)) is formed between the mutually opposing outer circumferential surface (11a) of the sleeve (11) and inner circumferential surface (12b) of the housing (12), and the formation region for this squeeze film (S (S1)) can be changed.
(FR) L'invention concerne une structure d'amortissement ayant : un manchon (11) qui se trouve sur une partie d'extrémité axiale (3a) s'étendant vers l'extérieur par rapport à un palier qui supporte un essieu (3), et qui se trouve sur la circonférence extérieure de la partie d'extrémité axiale (3a) ; un logement (12) qui se trouve dans le sens radial par rapport au manchon (11) et à l'essieu (3), laissant un intervalle ; et une pièce mobile (13) qui déplace relativement le logement (12) et le manchon (11) dans le sens axial. De plus, un film d'huile (S (S1)) est formé entre la surface circonférentielle extérieure (11a) du manchon (11) et la surface circonférentielle intérieure (12b) du logement (12) mutuellement opposées, et la région de formation pour ce film d'huile (S (S1)) peut être changée.
(JA)  本発明のダンパー構造は、軸受に支持された軸(3)の前記軸受より外側に延びる軸端部(3a)に設けられ、軸端部(3a)の外周に設けられるスリーブ(11)と、このスリーブ(11)と軸(3)の径方向に間隔を置いて設けられたハウジング(12)と、ハウジング(12)とスリーブ(11)とを軸方向に相対移動させる移動部(13)とを備え、互いに対向するスリーブ(11)の外周面(11a)とハウジング(12)の内周面(12b)との間にスクイズフィルムS(S1)が形成され、このスクイズフィルムS(S1)の形成域が変更可能である。
