본 고안은 로타리 압축기에 관한 것으로써, 더욱 상세하게는 냉매가스를 흡입하여 압축할 때 실린더의 내주면과 로울러 외주면 사이에서 발생되는 냉매 가스의 누설을 최소화 함에 따라 압축효율을 높여주는 로타리압축기에 관한 것이다.The present invention relates to a rotary compressor, and more particularly, to a rotary compressor that increases compression efficiency by minimizing leakage of refrigerant gas generated between an inner circumferential surface of a cylinder and an outer circumferential surface of a cylinder when the refrigerant gas is sucked and compressed. .
일반적으로 압축기는 냉동 및 냉장을 목적으로 하는 싸이클하에서 냉매가스를 흡입하여 압축하고 토출시키는 기능을 하는 것으로, 이러한 종래의 압축기가 제1도에서와 같이 도시되어 있다.Generally, the compressor functions to suck, compress, and discharge the refrigerant gas under a cycle for refrigeration and refrigeration. Such a conventional compressor is illustrated in FIG.
이 압축기는 밀폐된 하우징(1)내에 고정자(2)와 회전자(2')로 된 구동부를 가지며, 이 구동부에는 회전력을 전달하여 주는 축(3)이 압입·고정되어 있다.This compressor has a drive part consisting of a stator 2 and a rotor 2 'in a sealed housing 1, in which a shaft 3 for transmitting rotational force is press-fitted and fixed.
축(3)이 연장된 하단부에는 그 외주면으로 로울러(5)가 결합되는 편심부(4)가 형성되며, 이 편심부와 로울러는 냉매를 흡입하여 압축하고 토출시키는 실린더(6)내에 실치되어 흡입구(7)를 통하여 흡입되는 냉매를 고온·고압으로 압축시켜 토출하는 작용을 수행한다.At the lower end of which shaft 3 extends, an eccentric portion 4 is formed to which rollers 5 are coupled to its outer circumferential surface. The eccentric portion and the roller are mounted in a cylinder 6 which sucks, compresses and discharges refrigerant. The refrigerant sucked through (7) is compressed to high temperature and high pressure and discharged.
그러나 상기한 종래기술은 편심부에 결합된 로울러가 실린더의 내주면상에서 회전할 때 압력차 및 마찰충격등에 의해 간헐적으로 틈이 생기게 되고, 이때 형성된 틈새를 통하여 누설이 발생되어 압축기의 체적효율이 크게 저하되는 문제점이 있었다.However, in the above-described conventional technique, when a roller coupled to an eccentric part rotates on an inner circumferential surface of a cylinder, an intermittent gap is generated due to a pressure difference and a frictional impact, and at this time, leakage occurs through the formed gap, thereby greatly reducing the volumetric efficiency of the compressor. There was a problem.
본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로써, 본 고안의 목적은 냉매의 압축 및 토출동작시 누설을 방지하는 로터리 압축기를 제공하는 것이다.The present invention has been made in view of the above problems, the object of the present invention is to provide a rotary compressor to prevent leakage during the compression and discharge operation of the refrigerant.
이러한 본 고안은, 축에 형성된 편심부에 로울러를 결합할 때 축중심선에 가까운 편심부에 단성부재를 개재하므로써, 로울러의 회전시 그 외주면이 실린더의 내주면에 더욱 밀착하여 회전할 수 있는 힘을 편심부가 제공하고, 이에 의해 실린더에 유입되는 냉매의 압력차이로 인한 누설을 최소화 하는 것을 특징으로 한다.The present invention, when the roller is coupled to the eccentric portion formed on the shaft through the unit member in the eccentric portion close to the axial center line, the eccentric force that can rotate the outer peripheral surface more closely to the inner peripheral surface of the cylinder during rotation of the roller It provides additional, thereby minimizing the leakage due to the pressure difference of the refrigerant flowing into the cylinder.
도면 제2도 내지 제3도는 본 고안의 실시예를 나타낸 것으로써, 제2도중 도면 부호(40)는 실린더이며, 이실린더(40)는 냉매가스가 흡입되는 흡입구(41)와 흡입된 냉매가스를 토출하는 토출구(42)가 구비되어 있다.2 to 3 show an embodiment of the present invention, in FIG. 2, reference numeral 40 is a cylinder, and the cylinder 40 is a suction port 41 through which refrigerant gas is sucked and a refrigerant gas sucked in. A discharge port 42 for discharging the gas is provided.
상기 실린더(40)내에는 축(10)의 하부로 형성된 편심부(11)가 설치되며, 이 편심부의 외측으로는 실린터(40)의 내주면을 따라 이동되고 회전하는 로울러(20)가 결합되어 있다.An eccentric portion 11 formed below the shaft 10 is installed in the cylinder 40, and an outer roller 20 is moved and rotated along the inner circumferential surface of the cylinder 40 to the outside of the eccentric portion. have.
한편, 편심부(11)에는 이 편심부의 외주면상으로 돌출되게 탄성부재(30)가 취부되는데, 이때 탄성부재의 취부위치는 축(10)의 중심선으로 부터 근접되고 중심선으로 부터 원거리인 편심부(11)에 대해 반대위치에 취부하는 것이 바람직하다.On the other hand, the eccentric portion 11 is mounted with an elastic member 30 to protrude on the outer circumferential surface of the eccentric portion, wherein the mounting position of the elastic member is close to the center line of the shaft 10 and distant from the center line ( It is preferable to mount it in the opposite position with respect to 11).
따라서, 상기와 같은 본 고안은, 고정자와 회전자로 된 구동부에 의해 축(10)이 회전되고, 이 축에 형성된 편심부(11)와 그 외측으로 결합된 로울러(20)는 실린더(40)내에서 일체로 연동된다.Therefore, the present invention as described above, the shaft 10 is rotated by the drive unit made of the stator and the rotor, the eccentric portion 11 formed on the shaft and the roller 20 coupled to the outside is the cylinder 40 Interlocked integrally within.
이에 의하여 흡입구(41)를 통해 유입된 냉매가스는, 제3도에서와 같이 편심 구동되는 로울러(20)와 베인(21)의 작동에 의해 압축되고 압축된 냉매가스는 토출구(42)를 통하여 실린더(40)로 부터 토출된다.As a result, the refrigerant gas introduced through the suction port 41 is compressed by the operation of the roller 20 and the vane 21 which are eccentrically driven as shown in FIG. 3, and the compressed refrigerant gas is discharged through the discharge port 42. It is discharged from 40.
상기 압축·토출과정에서 편심구동되는 로울러(20)와 이 로울러에 구동력을 전달하여 주는 편심부(11) 사이에는 탄성부재(30)가 개재되어 있으므로, 이 탄성부재의 작용에 의해 로울러(20)의 편심구동시 상기 편심부(11)가 실린더(40)의 내주면에 더욱 밀착된 상대로 구동시킬 수 있는 힘을 제공한다.Since the elastic member 30 is interposed between the roller 20 eccentrically driven during the compression and discharge process and the eccentric portion 11 which transmits the driving force to the roller, the roller 20 is actuated by the action of the elastic member. When the eccentric drive of the eccentric portion 11 provides a force that can be driven to a relative closer to the inner peripheral surface of the cylinder (40).
그러므로, 실린더(40)에 유입된 냉매가스를 압축하기 시작한 초기에 비해 압력이 높게 변화되는 중간 이후과정에서 압력차이 또는 마찰충격등으로 인해 로울러(20)의 외주면이 실린더(40)의 내주면으로부터 떨어질려는 작용을 상기의 탄성부재(30)가 방지하여 준다.Therefore, the outer circumferential surface of the roller 20 may fall from the inner circumferential surface of the cylinder 40 due to the pressure difference or frictional impact in the middle and subsequent processes in which the pressure changes higher than the initial time when the refrigerant gas flowing into the cylinder 40 starts to be compressed. The elastic member 30 prevents the action.
또한, 축(10)의 중심선으로 부터 최장거리에 위치한 편심부(11)가 실린더(40)의 내주면에 로울러(20)를 밀착시키고 이때 발생된 반발력이 작용하는 부위, 즉 축(10) 중심선으로 부터 최단거리의 편심부(11) 외주면에 탄성부재(30)가 설치되어 있으므로, 로울러(20)의 편심구동시 반발력을 상쇄시키는 작용과 더불어 탄성력을 유발시켜 냉매의 누설을 방지하는 것이다.In addition, the eccentric portion 11 located at the longest distance from the center line of the shaft 10 is in close contact with the roller 20 on the inner circumferential surface of the cylinder 40, and the repulsive force generated at this time, that is, the axis 10 to the center line Since the elastic member 30 is installed on the outer circumferential surface of the eccentric portion 11 of the shortest distance, the repulsive force is canceled during the eccentric driving of the roller 20 and the elastic force is induced to prevent leakage of the refrigerant.
이와 같은 본 고안 실시예는 압축기의 구동시 형성되는 틈새로 인한 누설을 최소화하여 압축효율을 높일수 있는 효과가 있으며, 또한 단위 체적당 효율의 향상으로 인해 기기의 크기를 소형화 시킬 수 있는 장점이있다.Such an embodiment of the present invention has the effect of minimizing the leakage due to the gap formed when driving the compressor to increase the compression efficiency, and also has the advantage of miniaturizing the size of the device due to the improvement of efficiency per unit volume.
