Title (EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À VOLUTE
(JA) スクロール型圧縮機
Abstract:
(EN) A scroll compressor is provided with: a rotating shaft (20) rotatably supported by a housing; a crank pin (34) eccentrically and integrally formed on the upper end side of the rotating shaft; and an eccentric bush (36) fitted to the crank pin and imparting orbital motion to a movable scroll as the rotating shaft is rotated. The eccentric bush has: a crank pin hole (38) into which the crank pin is inserted and fitted; and introduction paths (54, 55) provided in the end surface (36a), which is on the rotating shaft side, at positions facing each other across the crank pin hole, the introduction paths (54, 55) introducing lubricating oil to the fit section at which the crank pin and the crank pin hole are fitted to each other.
(FR) L'invention concerne un compresseur à volute qui comprend : un arbre rotatif (20) supporté de façon rotative par un carter ; un maneton de vilebrequin (34) qui est formé de façon excentrique et solidairement sur le côté d'extrémité supérieure de l'arbre rotatif ; et un coussinet excentrique (36) monté sur le maneton de vilebrequin et qui imprime un mouvement orbital à une volute mobile lorsque l'arbre rotatif tourne. Le coussinet excentrique comprend : un alésage de maneton de vilebrequin (38) dans lequel le maneton de vilebrequin est logé et ajusté ; et des trajets d'introduction (54, 55) formés dans la surface terminale (36a) qui se trouve sur le côté de l'arbre rotatif, dans des positions qui se font face dans le plan de l'alésage du maneton de vilebrequin, les trajets d'introduction (54, 55) introduisant une huile lubrifiante dans la section d'ajustement dans laquelle le maneton de vilebrequin et l'alésage de maneton de vilebrequin sont ajustés l'un à l'autre.
(JA)  ハウジングに回転自在に支持される回転軸(20)と、回転軸の上端側に偏心して一体形成されたクランクピン(34)と、クランクピンに嵌合され、回転軸の回転に伴い可動スクロールに旋回運動を付与する偏心ブッシュ(36)とを備え、偏心ブッシュは、クランクピンが挿入して嵌合されるクランクピン孔(38)と、回転軸側となる端面(36a)に、クランクピン孔を挟んで対向する位置に設けられ、潤滑油をクランクピンとクランクピン孔とが嵌合する嵌合部へ導入する導入通路(54,55)とを有する。
