Abstract
(EN) The purpose of the present invention is to provide a fluid machine capable of lubricating a lip seal with no difficulty even when an oil-impregnated sliding bearing is used as a drive shaft bearing. One end of a drive shaft (8) located on the opposite side from a scroll unit (6) projects through a front housing (4). A through opening (4A) is axially sealed with a lip seal (59). A main bearing (14) is provided so as to be installed inside the front housing and rotatably support a portion of the drive shaft located on the scroll unit side. The main bearing is configured with an oil-impregnated sliding bearing, and communication flow passages (63, 64) for causing an oil-containing fluid to flow toward the lip seal are formed between the main bearing and the front housing.
(FR) La présente invention concerne une machine hydraulique capable de lubrifier un joint à lèvre sans difficulté même lorsqu'un palier coulissant imprégné d'huile est utilisé comme palier d'arbre d'entraînement. Une extrémité d'un arbre d'entraînement (8) située en regard d'une unité à volutes (6) fait saillie à travers un logement avant (4). Une ouverture traversante (4A) est scellée axialement à l'aide d'un joint à lèvre (59). Un palier principal (14) est disposé de manière à être installé à l'intérieur du logement avant et à porter en rotation une partie de l'arbre d'entraînement située du côté de l'unité à volutes. Le palier principal comprend un palier coulissant imprégné d'huile, et des passages d'écoulement de communication (63, 64) destinés à amener un fluide contenant de l'huile à s'écouler vers le joint à lèvre sont formés entre le palier principal et le logement avant.
(JA) 駆動軸の軸受として含油滑り軸受を使用したときにも、リップシールの潤滑を支障無く行うことができる流体機械を提供する。駆動軸(8)のスクロールユニット(6)とは反対側の端部がフロントハウジング(4)を貫通して突出する。貫通部(4A)をリップシール(59)にて軸封する。フロントハウジング内に取り付けられ、駆動軸のスクロールユニット側の部分を回転自在に支持する主軸受(14)を備える。主軸受は含油滑り軸受にて構成され、主軸受とフロントハウジングの間に、リップシール側にオイルを含む流体を流通させる連通流路(63)、(64)が形成されている。
