Bearing lubrication system for a scroll compressor

스크롤 콤프레사는 흡입 압력하에 유체를 받아들이는 흡입 압력실(98)과 배출 압력하에 유체를 배출하는 배출 압력실(110)을 갖고 있으며, 흡입 압력실과 배출 압력실에 연결된 스크롤 부재(56,58), 고정 및 궤도 스크롤 부재에 의하여 형성된 중간 압력실(81), 오일 저장조(46), 모터(32) 및 모터와 궤도 스크롤 부재에 연결된 크랭크샤프트(34)를 포함함. 크랭크샤프트는 오일 저장조까지 연장된 길이 방향의 오일 통로(52,54)와 전술한 오일 통로를 방사방향의 외부에 연결하는 제1 통공(624)을 갖고 있음. 로울러(82)는 크랭크샤프트 외주 표면 주위에 설치되어 궤도 스크롤 부재와 크랭크샤프트를 연결함. 로울러는 내주 및 외주 표면과 전술한 제1 통공에 연결되어 오일 통로에서 이송되는 오일을 외부로 공급하는 제2 통공(622)을 갖고 있음. 베어링(57)은 로울러와 궤도 스크롤 부재 사이에 설치되었음. 오일 수집 공간부(55)는 베어링에 근접되게 형성되었으며, 궤도 스크롤의 이면(636)과 로울러 및 크랭크샤프트의 단부 표면에 의하여 형성됨. 중간 압력실과 오일 수집 공간부는 서로 연결되었음. 오일은 베어링을 통하여 제2 통공으로부터 오일 수집 공간부로 이송됨. 전술한 오일 수집 공간과 고정 및 궤도 스크롤 부재 사이의 중간 압력 공간부 사이에 제3의 통공(626)이 형성되어 오일이 전술한 제3의 통공을 통하여 오일 수집 공간으로부터 중간 압력 공간으로 공급되게 되었음. The scroll compressor has a suction pressure chamber 98 for receiving fluid under suction pressure and a discharge pressure chamber 110 for discharging fluid under discharge pressure, and scroll members 56 and 58 connected to the suction pressure chamber and the discharge pressure chamber. And an intermediate pressure chamber 81, an oil reservoir 46, a motor 32, and a crankshaft 34 connected to the motor and the orbital scroll member, formed by the fixed and orbital scroll members. The crankshaft has longitudinal oil passages 52, 54 extending to the oil reservoir and a first aperture 624 for connecting the aforementioned oil passages to the radially outside. The rollers 82 are installed around the crankshaft outer circumferential surface to connect the orbiting scroll member and the crankshaft. The roller has a second through hole 622 connected to the inner circumferential and outer circumferential surfaces and the aforementioned first through hole to supply the oil conveyed from the oil passage to the outside. Bearing 57 is installed between the roller and the track scroll member. The oil collection space 55 is formed close to the bearing and is formed by the back surface 636 of the orbital scroll and the end surfaces of the rollers and crankshafts. ...
