Title
(EN) ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE
(FR) COMPRESSEUR ROTATIF ET DISPOSITIF À CYCLE DE RÉFRIGÉRATION

Abstract
(EN) [Problem] To provide a rotary compressor in which a rotation shaft is axially supported by at least three bearing portions, and a refrigeration cycle device, the rotary compressor being capable of easily aligning the bearing portions and suppressing the occurrence of tilting and whirling of the rotation shaft. [Solution] A compression mechanism portion has at least three cylinders arranged in an axial direction of a rotation shaft, a blocking member blocking both ends of the cylinders and forming a cylinder chamber in each of the cylinders, and a roller that eccentrically rotates in the cylinder chamber. The rotation shaft is axially supported by bearing portions provided to at least three of the blocking members. When the clearance of a slide part between an inner circumferential surface of the bearing portion and an outer circumferential surface of the rotation shaft is "C", and the length in the axial direction between the inner circumferential surface of the bearing portion and the outer circumferential surface of the rotation shaft is "L", the value of "C/L" of the bearing portion closest to an electrical motor unit is smaller than the values of "C/L" of the other bearing portions.
(FR) L'invention vise à procurer un compresseur rotatif, dans lequel compresseur un arbre de rotation est supporté axialement par au moins trois parties palier, et un dispositif à cycle de réfrigération, le compresseur rotatif étant apte à aligner facilement les parties palier et à éliminer l'apparition d'une inclinaison et d'un tourbillonnement de l'arbre de rotation. A cet effet, selon l'invention, une partie mécanisme de compression comprend au moins trois cylindres disposés dans une direction axiale d'un arbre de rotation, un élément de blocage bloquant les deux extrémités des cylindres et formant une chambre de cylindre dans chacun des cylindres, et un rouleau qui tourne de façon excentrée dans la chambre de cylindre. L'arbre de rotation est supporté axialement par des parties paliers disposées sur au moins trois éléments de blocage. Quand l'espacement d'une partie de coulissement entre une surface périphérique interne de la partie palier et une surface périphérique externe de l'arbre de rotation est "C", et que la longueur dans la direction axiale entre la surface périphérique interne de la partie palier et la surface périphérique externe de l'arbre de rotation est "L", la valeur "C/L'" de la partie palier la plus proche d'une unité de moteur électrique est inférieure aux valeurs "C/L" des autres parties palier.
(JA) 少なくとも三つの軸受部を用いて回転軸を軸支する回転式圧縮機において、軸受部の調芯を容易に行え、回転軸の傾きや振れ回りの発生を抑制できる回転式圧縮機及び冷凍サイクル装置を提供する。 【解決手段】圧縮機構部は、回転軸の軸方向に配列された少なくとも三つのシリンダと、シリンダの両端を閉塞して各シリンダ内にシリンダ室を形成する閉塞部材と、シリンダ室内で偏心回転するローラとを有し、回転軸は閉塞部材の少なくとも三つに設けられた軸受部により軸支され、軸受部の内周面と回転軸の外周面との間の摺動部分のクリアランスを"C"、軸受部の内周面と回転軸の外周面との間の軸方向の長さを"L"とした場合、電動機部の最も近くに位置する軸受部の"C/L"の値は、他の軸受部の"C/L"の値より小さい。
