본 고안은 용접에 의해 열변형이 생기는 것을 방지하여 압축요율을 높여 주는 열변형 방지용 로터리 콤프레서에 관한 것이다.The present invention relates to a rotary compressor for preventing the heat deformation to prevent heat deformation caused by welding to increase the compression rate.
일반적으로 로터리 콤프레서는 제1도와 제2도에서 도시되는 바와같이, 밀폐용기(1) 내주면에 실린더(2) 외측면이 고정되고, 실린더(2) 상단에 메인베어링(3)이 고정되며, 실린더(2) 하단에 서브베어링(4)이 고정되고, 전동기(5)의 회전축(6)이 메인베어링(3)과 서브베어링(4)의 허브에 회전 가능하게 관통되며, 실린더92) 내부에 편심롤러(7)가 회전축(6)과 일쳬로 회전 가능하게 끼워지고, 실린더(2) 측벽부에 스프링(8)에 탄지되는 베인(9)이 돌출되며, 베인(9)의 선단부가 편심롤러(7) 외주연에 슬라이드 가능하게 밀착되어 있다.In general, the rotary compressor, as shown in FIG. 1 and FIG. 2, the outer surface of the cylinder 2 is fixed to the inner circumferential surface of the sealed container 1, and the main bearing 3 is fixed to the upper end of the cylinder 2. (2) The sub-bearing 4 is fixed to the lower end, the rotating shaft 6 of the electric motor 5 rotatably penetrates the main bearing 3 and the hub of the sub-bearing 4, and is eccentric inside the cylinder 92. The roller 7 is rotatably fitted with the rotation shaft 6, and the vane 9 supported by the spring 8 protrudes from the side wall of the cylinder 2, and the tip of the vane 9 has an eccentric roller ( 7) Sliding close to the outer periphery.
이와같이 구성되는 종래 콤프레서는 전동기(5)의 회전축(6)과 일체로 회전되는 편심롤러(7) 외주면에 스프링(8)의 탄발력을 받는 베인(9)이 종으로 밀착되어, 편심롤러(7)가 회전하면 편심된 외주면을 따라 왕복으로 작동되고, 편심롤러(7)의 일정위치에 이를 때까지 흡입된 냉매를 가로막아 압축되도록 한다.The conventional compressor configured as described above has the vane 9 subjected to the elastic force of the spring 8 to the outer circumferential surface of the eccentric roller 7 which is integrally rotated with the rotary shaft 6 of the electric motor 5, and is closely contacted with the eccentric roller 7. Rotation) is reciprocated along the eccentric outer circumferential surface, so as to block and compress the sucked refrigerant until it reaches a predetermined position of the eccentric roller (7).
여기에서 실린더(2)는 외측면이 밀폐용기(1) 내주면에 용접되어 고정되고 기밀을 유지하도록 되어 있다.In this case, the cylinder 2 is welded to the inner circumferential surface of the hermetic container 1 to be fixed and kept airtight.
이러한 종래 콤프레서는 밀폐용기(1) 내주면에 실린더(2) 외측면을 용접할 때, 용접열에 의해 실린더(2)에 열변형이 생겼으며, 이로 인해 마찰력이 증대되고 기밀유지가 저하되어, 냉력이 떨어지고 콤프레서의 전체효율이 떨어지는 결함이 있었다.When the conventional compressor welds the outer surface of the cylinder 2 to the inner circumferential surface of the airtight container 1, heat deformation occurs in the cylinder 2 due to the heat of welding, which increases the frictional force and lowers the airtightness, thereby reducing the cold power. There was a defect that dropped and the overall efficiency of the compressor fell.
본 고안의 목적은 열변형이 생기는 것을 방지하여 압축효율을 높여 주기 위한 것으로, 메인베어링과 서브베어링의 외주면을 연장시켜 밀폐용기 내주면에 용접한 열변형 방지용 로터리 콤프레서를 제공하는데 있다.An object of the present invention is to improve the compression efficiency by preventing the heat deformation, and to provide a rotary compressor for preventing heat deformation welded to the inner peripheral surface of the sealed container by extending the outer peripheral surface of the main bearing and the sub-bearing.
이하 첨부된 도면에 따라 본 고안의 실시예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention according to the accompanying drawings in detail.
본 고안이 적용되는 콤프레서도 제3도에서 도시되는 바와같이 밀폐용기(1) 내주면에 압축장치의 실린더(30) 외측면이 고정되고, 실린더(30)이 고정되고, 전도기(5)의 회전축(6)이 메인베어링(3)과 서브베어링(20)의 허브에 회전 가능하게 관통되며, 실린더(30) 내부에 편심롤러(7)가 회전축(6)과 일체로 회전가능하게 끼워지고, 실린더(30) 측벽부에 스프링에 탄지되는 베인(미도시)이 돌출되며, 베인의 선단부가 편심롤러(7) 외주연에 밀착되는 것은 종래와 같다. 단, 본 고안은 메인베어링(10)의 외측면이 외측으로 연장되어 용착부(11)가 형성되고, 서브베어링(22) 외측면이 외측으로 연장되어 용착부(21)가 형성되어, 밀폐용기(1) 내주면에 용착부가 용착되어 실린더(30)가 메인베어링(10)과 서브베어링(20)에 의해 지지되도록 구성함을 그 기술적 특징으로 한다.Compressor to which the present invention is applied, as shown in FIG. 3, the outer surface of the cylinder 30 of the compression device is fixed to the inner circumferential surface of the sealed container 1, the cylinder 30 is fixed, and the rotating shaft of the conductor 5 ( 6) rotatably penetrates the hub of the main bearing 3 and the sub-bearing 20, the eccentric roller 7 is fitted into the cylinder 30 so as to be integrally rotatable with the rotation shaft 6, the cylinder ( 30) A vane (not shown) supported by a spring protrudes from the side wall portion, and the tip of the vane is in close contact with the outer circumference of the eccentric roller 7 as in the prior art. However, in the present invention, the outer surface of the main bearing 10 extends to the outside to form a welded portion 11, and the outer side of the sub bearing 22 extends to the outside to form a welded portion 21, the sealed container. (1) The welded portion is welded to the inner circumferential surface so that the cylinder 30 is configured to be supported by the main bearing 10 and the sub-bearing 20.
여기에서, 용착부(11),(21)는 메인베어링(10)과 서브베어링(20) 외측면이 외측으로 연장되고, 끝부분이 상하로 절곡 연장되어 밀폐용기(1) 내주면에 밀착된다.Here, the welded parts 11 and 21 have an outer surface of the main bearing 10 and the sub bearing 20 extending outwards, and the ends thereof are bent up and down to be in close contact with the inner circumferential surface of the sealed container 1.
이와같이 구성되는 본 고안은 압축장치의 메인베어링(10)과 서브베어링(20)의 외측면이 각기 외측으로 연장되어 용착부(11),(21)가 밀폐용기(1) 내주면에 용접되므로, 종래에 비해 실린더(30)로부터 먼곳에 용착부(11),(21)가 형성되어, 용접데 의한 열변형이 적게 된다.The present invention configured as described above is because the outer surface of the main bearing 10 and the sub-bearing 20 of the compression device are respectively extended to the outside so that the welded portions 11, 21 are welded to the inner peripheral surface of the sealed container 1, In contrast, welded portions 11 and 21 are formed far from the cylinder 30, resulting in less heat deformation due to welding.
한편, 제4도는 본 고안의 다른 실시예로서 실린더(30)의 외측면 외측으로 연장시켜 용착부(31)를 형성시키고, 밀폐용기(1) 내주면에 용착부(31)를 부착시켰다.On the other hand, Figure 4 as another embodiment of the present invention extends to the outside of the outer surface of the cylinder 30 to form a weld portion 31, the weld portion 31 is attached to the inner peripheral surface of the sealed container (1).
이러한 본 고안은 용착부(11),(21)(31)가 실린더(30) 중심부로부터 멀리 형성되므로 열변형을 적게 받게 된다. 따라서, 용접할 때 변형이 적게 되어 기밀유지가 증대되고 마찰력의 증대가 억제되며, 콤프레서의 전체요율이 증대되는 장점이 있다.The present invention is less welded (11, 21) 31 is formed from the center of the cylinder 30 so that less heat deformation. Therefore, there is an advantage that the deformation is small during welding, the airtightness is increased, the increase in frictional force is suppressed, and the overall rate of the compressor is increased.
이상에서 살펴본 바와같이 본 고안은 압축장치의 메인베어링과 서브베어링의 외측면을 연장시켜 용착부를 형성하고, 용착부가 밀폐용기 내주면에 용접되도록 하므로, 열변형이 생기는 것을 방지하여 압축효율을 높여 주는 매우 유용한 것이다.As described above, the present invention extends the outer surfaces of the main bearing and the sub-bearing of the compression device to form a welded portion, and the welded portion is welded to the inner circumferential surface of the sealed container, which prevents thermal deformation and increases compression efficiency. It is useful.
