본 발명은 회전형 압축기의 실린더 결합장치에 관한 것으로 특히 케이스와 실린더의 용접 부위를 통하여 압축부에서 발생하는 진동이 압축기 케이스를 가진함으로써 소음을 방사하는 문제를 해결하는데 목적이 있다.The present invention relates to a cylinder coupling device of a rotary compressor, and in particular, an object of the present invention is to solve the problem of radiating noise by vibrating from the compression part through the welding part of the case and the cylinder with the compressor case.
종래의 회전형 압축기에 대하여 제1도에 나타낸 압축기의 단면도에서 설명한다. 일반적으로 압축기는 밀폐용기 내부에서 냉매가스를 압축하는 압축장치와 회전 운동에 의하여 압축작용을 하기 위한 동력을 공급하는 구동장치로 구성된다. 회전형 압축기는 밀폐형 케이스(12)로 이루어지는 내부공간의 상부에 고정자(10)이 열박음되어 있고, 내부에 회전자(11)이 구성되어 구동부를 형성하며, 회전자(11)은 회전축(1)과 결합되어 회전력을 압축부로 전달한다. 압축부는 압축실(4)의 외면을 형성하며 케이스(12)와 용접결합되어 압축부를 지지하는 실린더(3)과, 편심 회전축(1)의 회전운동에 따라 실린더(3)내면과 접촉하면서 압축작용을 하는 로울러(2)와, 실린더(3)과 결합되어 회전축(1)을 지지하면서 베인(14), 롤러와 함께 압축실(4)을 형성하는 주베어링(7)과 보조베어링(8), 그리고 실린더(3)로 흡입되거나 토출되는 가스의 유동통로가 되는 흡입구(5)및 토출구(6)로 구성되어 있다. 주베어링(7)에는 실린더(3)내부와 컴프레서 내부 공간의 압력차이에 의하여 압축가스의 유출을 조절하는 토출 밸브가 설치된다. 실린더(3)을 중심으로 구성되는 압축부를 밀폐형 케이스(12)내부에 고정하기 위하여 실린더(3)외면과 케이스(12)내부 접촉면에 용접을 실시한다.A conventional rotary compressor will be described in cross section of the compressor shown in FIG. In general, the compressor is composed of a compression device for compressing the refrigerant gas in the sealed container and a drive device for supplying power for the compression action by the rotary motion. In the rotary compressor, the stator 10 is constricted in the upper portion of the inner space formed of the sealed case 12, and the rotor 11 is formed therein to form a driving unit, and the rotor 11 includes the rotating shaft 1. ) Is transmitted to the compression unit. The compression unit forms an outer surface of the compression chamber 4 and is welded and coupled to the case 12 to support the compression unit, and to contact the inner surface of the cylinder 3 in accordance with the rotational movement of the eccentric rotation shaft 1 for the compression action. The main bearing (7) and the auxiliary bearing (8), which combine with the roller (2) and the cylinder (3) to support the rotating shaft (1) and form the compression chamber (4) together with the roller (3) And a suction port 5 and a discharge port 6 serving as flow paths of the gas sucked into or discharged from the cylinder 3. The main bearing 7 is provided with a discharge valve for controlling the outflow of the compressed gas by the pressure difference between the cylinder 3 and the compressor internal space. Welding is performed on the outer surface of the cylinder 3 and the inner contact surface of the case 12 in order to fix the compression part formed around the cylinder 3 inside the sealed case 12.
다음으로 종래의 회전형 압축기의 동작에 관해 설명한다 전동부의 모터가 회전함에 따라 흡입구(5)을 통하여 냉매가스가 압축실(4)로 빨려들어가며, 로울러(2)의 회전에 의해 압축실(4)의 체적이 축소되면서 압력이 토출압럭까지 상승된 후 토출구(6)을 통과하여 주베어링(7)에 설치되어 있는 밸브의 작동에 따라 주베어링(7)의 상부에 위치한 소음기(9)내부의 공간으로 토출된다.Next, the operation of the conventional rotary compressor will be described. As the motor of the electric motor rotates, the refrigerant gas is sucked into the compression chamber 4 through the suction port 5, and the compression chamber ( As the volume of 4) decreases, the pressure rises to the discharge pressure lump, and then passes through the discharge port 6 to operate the valve installed in the main bearing 7. Is discharged into the space.
이상과 같은 작용에 의하여 실린더(3)내부에서 이루어지는 냉매가스의 압축 및 토출 과정에서 발생하는 충격 진동과 압축부 구성 요소 부품들의 마찰 및 전자기력의 불균형에 기인하는 회전부 요동에 의한 진동 성분이 실린더(3)로 전파되어 실린더(3)과 용접되어 있는 케이스(12)을 진동시킴으로써 압축기 외부로 소음을 발생시킨다.By virtue of the above-described action, the vibration component caused by the vibration of the rotating part due to the shock vibration generated during the compression and discharge of the refrigerant gas inside the cylinder 3 and the friction of the components of the compression part and the imbalance of the electromagnetic force is applied to the cylinder 3. Noise is generated outside the compressor by vibrating the case 12 which propagates to the cylinder 3 and is welded to the cylinder 3.
종래의 회전형 압축기에서 밀폐 케이스(12)에 압축부를 체결하기 위하여 용접을 실시하고 있다. 용접 과정은 고열을 발생하기 때문에 용접 부위의 고열이 압축기 실린더(3)로 전달되어 정밀가공을 요하는 실린더(3)에 열변형을 일으키게 된다. 현재 이러한 실린더(3)의 용접 열변형 문제를 해결하기 위하여 열전달을 줄이기 위한 구조로써 실린더(3)의 외부에 공간부(13)을 형성하고, 용접 부분을 최소화하기 위하여 3점 지지 점(spot)용접을 실시하고 있으나, 용접시 열변형 문제를 완전히 해결하는데는 어려움이 있기 때문에 용접 작업에 주의가 요구된다.In the conventional rotary compressor, welding is performed to fasten the compression part to the sealed case 12. Since the welding process generates high heat, high heat of the welded portion is transmitted to the compressor cylinder 3, causing heat deformation in the cylinder 3 requiring precision processing. In order to solve the problem of heat deformation of the welding of the cylinder 3, a space 13 is formed on the outside of the cylinder 3 as a structure for reducing heat transfer, and a three-point support point is provided to minimize the welding portion. Although welding is carried out, it is difficult to completely solve the heat deformation problem during welding.
또한, 밀폐 케이스(12)에 압축부 실린더(3)을 용접하여 체결함으로써 압축부와 케이스(12)가 강하게 결합되는 장점이 있으나, 강하게 결합된 실린더(3)과 케이스(12)의 용접부위(20)를 통하여 압축 과정에서 발생하는 충격 진동, 압축기 부품간의 상대 운동에 의하여 발생하는 마찰 및 요동에 기인하는 압축부 진동이 압축기 케이스(12)을 가진하는 현상이 발생한다. 강결합을 이루는 용접부위(20)는 진동 전달율이 높은 진동 전달경로 역할을 함으로써 압축부 진동 성분이 압축기의 밀폐 케이스(12)로 전달되어 케이스(12)를 가진하는 진동원으로써 작용하게 되며, 케이스(12)의 고유 진동모드와 공진을 일으키면서 외부로 소음을 방사하는 문제점이 있다.In addition, there is an advantage that the compression part and the case 12 are strongly coupled by welding and fastening the compression part cylinder 3 to the sealed case 12, but the welding part of the strongly coupled cylinder 3 and the case 12 ( Through 20), a phenomenon in which the compression part vibration due to the shock vibration generated during the compression process, the friction and the fluctuation caused by the relative movement between the compressor parts has the compressor case 12 is generated. The welded part 20 which forms a strong coupling serves as a vibration transmission path having a high vibration transmission rate, and thus the compression part vibration component is transmitted to the sealed case 12 of the compressor to act as a vibration source having the case 12. There is a problem of emitting noise to the outside while causing resonance with the natural vibration mode of (12).
따라서 본 발명은 종래의 문제짐을 감안하여 케이스의 실런더의 용접부위를 통하여 압축부에서 발생하는 진동이 압축기 케이스를 가진함으로써 소음을 방사하는 문제를 해결하기 위한 것이다. 이하 본 발명의 구성 및 작용 효과를 첨부도면에 의거하여 설명하면 다음과 같다.Accordingly, the present invention is to solve the problem of radiating noise by vibrating from the compression part through the welding part of the cylinder of the case having a compressor case in consideration of the conventional problem. Hereinafter, the configuration and operation of the present invention will be described based on the accompanying drawings.

Is formed.
본 발명의 결합장치(130)의 세부 형상을 제4도에 나타낸다. 결합장치(130)은 보조베어링(108)하부의 원주면이 삽입되도록 원통형상으로 가공된 삽입부와 케이스(112)상면에 고정되는 고정부가 형성되어 있다. 보조베어링(108)의 삽입부에서 압축부를 확실히 지지하면서 결합되도록 삽입부 내면을 정밀가공하며, 맞물리는 결합장치(130)의 접촉 상대면에 제진 성능이 우수한 압축고무를 삽입하여 압축부에서 발생하는 진동이 결합부위를 거쳐 케이스(112)로 전달되는 것을 방지하도록 구성되어 있다. 압축기 하부케이스(112)상면에 고정되는 고정부에는 압축부 하부에서 회전축(101)의 작용에 의해 압축부로 유입되는 윤활유의 유동을 원활하게 하기 위하여 윤활유 유입홈(131)이 형성되어 있다. 그 이외의 구성과 동작설명은 종래의 구성과 동작과 동일하여 설명을 생략한다.The detailed shape of the coupling device 130 of the present invention is shown in FIG. Coupling device 130 is formed with a fixed portion fixed to the insertion portion and the case 112 is processed into a cylindrical shape so that the circumferential surface of the lower side of the auxiliary bearing 108 is inserted. The inner surface of the insertion part is precisely processed to securely engage the compression part at the insertion part of the auxiliary bearing 108, and a compression rubber having excellent vibration damping performance is inserted into the contact mating surface of the engaging device 130 to generate the compression part. It is configured to prevent the vibration is transmitted to the case 112 through the coupling portion. The fixed part fixed to the upper surface of the compressor lower case 112 is provided with a lubricating oil inflow groove 131 to smoothly flow the lubricating oil introduced into the compression part by the action of the rotating shaft 101 under the compression part.
