Title
(EN) ROTARY COMPRESSOR
(FR) COMPRESSEUR ROTATIF
(ZH) 旋转式压缩机
Abstract
(EN)
A rotary compressor comprises a housing (12); a compressing mechanism provided within the housing; a rotary shaft (100), a first end of the rotary shaft being provided with an eccentric crank pin (102), which eccentric crank pin drives the compressing mechanism via a driving bearing (64); a main bearing (62) for supporting part of the rotary shaft, the rotary shaft further comprising: a concentric hole (104) formed at a second end of the rotary shaft; a first eccentric hole (110) in fluid communication with the concentric hole and extending to an end face of the eccentric crank pin, a second eccentric hole (120) in fluid communication with the concentric hole and extending to the end face of the first end of the rotary shaft, and a transverse hole (130) formed at a position corresponding to the main bearing (64) and in fluid communication with the second eccentric hole (120). The present compressor enables reasonable distribution of the amounts of a lubricating oil flowing through the two eccentric holes.
(FR)
L'invention concerne un compresseur rotatif comprenant un carter (12); un mécanisme de compression disposé dans le carter; un arbre de rotation (100), une première extrémité de cet arbre de rotation étant pourvue d'un maneton excentrique (102) qui entraîne le mécanisme de compression par l'intermédiaire d'un palier d'entraînement (64); un palier principal (62) destiné à porter une partie de l'arbre de rotation, cet arbre de rotation comprenant en outre : un orifice concentrique (104) formé au niveau d'une deuxième extrémité de l'arbre de rotation ; un premier orifice excentrique (110) en communication fluidique avec l'orifice concentrique et s'étendant jusqu'à une face terminale du maneton excentrique, un deuxième orifice excentrique (120) en communication fluidique avec l'orifice concentrique et s'étendant jusqu'à la face terminale de la première extrémité de l'arbre de rotation, et un orifice transversal (130) ménagé au niveau d'une position correspondant au palier principal (64) et se trouvant en communication fluidique avec le deuxième orifice excentrique (120). Le compresseur selon l'invention permet une distribution raisonnable de quantités d'une huile lubrifiante circulant dans les deux orifices excentriques.
(ZH)
一种旋转式压缩机,包括:壳体(12);设置在壳体内的压缩机构,旋转轴(100),旋转轴的第一端设置有偏心曲柄销(102),偏心曲柄销经由驱动轴承(64)驱动压缩机构;支撑旋转轴的一部分的主轴承(62);旋转轴进一步包括:形成在旋转轴第二端的同心孔(104);与同心孔流体连通并延伸到偏心曲柄销的端面的第一偏心孔(110);与同心孔流体连通并且延伸到旋转轴的第一端的端面的第二偏心孔(120));形成在与主轴承(64)对应的位置处并且与第二偏心孔(120)流体连通的横向孔(130)。本压缩机能够合理地分配流过两个偏心孔的润滑油量。
