Description
본 발명은 밀폐형 압축기에 관한 것으로, 보다 상세하게는 회전축을 회전 가능하게 지지하는 프레임과, 회전축 외주면에 마련되는 회전자 간의 마찰을 저감할 수 있는 밀폐형 압축기에 관한 것이다.The present invention relates to a hermetic compressor, and more particularly, to a hermetic compressor capable of reducing friction between a frame rotatably supporting a rotating shaft and a rotor provided on an outer circumferential surface of the rotating shaft.
일반적으로 밀폐형 압축기는 밀폐공간 내로 냉매를 흡입하여 압축한 후 토출하는 장치로써, 냉매를 압축하는 압축장치(1)와 이를 구동하는 구동장치(2)로 구성된다.In general, a hermetic compressor is a device for sucking and compressing a refrigerant into a sealed space and then discharging the refrigerant. The hermetic compressor includes a compression device 1 for compressing a refrigerant and a driving device 2 for driving the refrigerant.
압축장치(1)는 밀폐공간을 형성하는 밀폐용기 내부에 마련되는 것으로, 압축실(1a)을 형성하는 실린더블록(1b)과, 압축실(1a) 내부를 왕복 운동하는 피스톤(1c)을 구비하고, 실린더블록 일측에는 외부와 연통된 흡입실 및 토출실이 각각 형성된 실린더헤드가 결합된다.The compression device 1 is provided inside a sealed container forming a closed space, and includes a cylinder block 1b forming a compression chamber 1a and a piston 1c for reciprocating the inside of the compression chamber 1a. The cylinder head is coupled to one side of the cylinder block, each of which has a suction chamber and a discharge chamber communicating with the outside.
구동장치는 자장을 형성하는 고정자와, 고정자와 전자기적으로 상호 작용하여 회전하는 회전자와, 회전자의 중공부에 압입 고정되어 회전자와 함께 회전하는 회전축을 구비하고, 회전축의 하단부에는 회전축의 회전운동을 직선운동으로 변환시켜줌으로써 피스톤을 진퇴시키는 커넥팅로드가 설치되게 된다.The drive device includes a stator that forms a magnetic field, a rotor that rotates electromagnetically and interacts with the stator, and a rotation shaft that is press-fitted to the hollow part of the rotor and rotates together with the rotor. By converting the rotary motion into a linear motion, the connecting rod for retracting the piston is installed.
또한, 회전축은 그 하부가 실린더블록 일측에 마련되는 프레임에 의해 회전 가능하게 지지되며, 회전자는 프레임의 상단에 지지된 상태로 회전을 하게 된다.In addition, the rotating shaft is rotatably supported by a frame, the lower portion of which is provided on one side of the cylinder block, and the rotor rotates while being supported on the upper end of the frame.

There is a problem that the reliability is lowered.
또한, 트러스트베어링(3)은 와셔(3a,3b)와 볼(3c) 간의 구름접촉을 이용하여 마찰소음을 어느 정도 저감할 수는 있으나, 볼(3c)과 와셔(3a,3b) 사이의 접촉에 의해 발생되는 근본적인 소음은 제거하지 못하는 한계가 있다.In addition, although the thrust bearing 3 can reduce the friction noise to some extent by using the rolling contact between the washer 3a, 3b and the ball 3c, the contact between the ball 3c and the washer 3a, 3b. There is a limit that can not remove the fundamental noise caused by.

That is, the rotor 32 is installed on the outer surface of the middle portion of the rotary shaft 33, the rotor 32 is to be supported by the upper end of the frame 34 to rotate.
한편, 도 3을 참조하면, 프레임(34)과 회전자(32) 사이의 마찰에 의해 발생되는 소음을 저감하기 위해 프레임(34)과 회전자(32) 간의 대향면에는 각각 제 1마그네트(41)와 제 2마그네트(42)가 설치되게 된다. 이는 두 마그네트(41,42) 간의 자기적 반발력을 이용하여 프레임(34)과 회전자(32) 간의 직접적인 마찰을 방지하기 위함이다.On the other hand, referring to Figure 3, in order to reduce the noise generated by the friction between the frame 34 and the rotor 32, the first magnet 41 on the opposing surface between the frame 34 and the rotor 32, respectively ) And the second magnet 42 is installed. This is to prevent direct friction between the frame 34 and the rotor 32 by using the magnetic repulsive force between the two magnets (41, 42).
두 마그네트(41,42)는 고리 형상을 갖는 것으로, 제 1마그네트(41)는 프레임(34) 상단에 설치되게 되며, 이를 위해 프레임(34) 상단에는 제 1마그네트(41)가 삽입되는 제 1홈부(34b)가 형성된다. 그리고 제 2마그네트(42)는 제 1마그네트(41)와 대향하는 회전자(42) 하면에 형성된 제 2홈부(32a)에 삽입되게 된다. 이때, 두 마그네트(41,42)는 서로 마주보는 면이 동일 극을 항하도록 마련되어야 할 것이다.The two magnets 41 and 42 have a ring shape, and the first magnet 41 is installed on the top of the frame 34.

다음에는 본 발명에 따른 밀폐형 압축기의 동작 및 그에 따른 효과를 설명한다.Next, the operation of the hermetic compressor according to the present invention and the effects thereof will be described.
먼저, 고정자(31)에 전원이 인가되면, 고정자(31)에 형성된 자장과 전자기적 상호작용을 하며 회전자(32)가 회전하게 되고, 이와 더불어 회전축(33) 또한 동시에 회전을 하게 된다. 그리고 회전축(33)의 회전 운동을 통해 회전축(33) 하단에 연결된 커넥팅로드(35)가 직선 왕복 운동을 하며 피스톤(22)을 진퇴시켜 압축실(21a)의 냉매를 압축하게 된다.First, when power is applied to the stator 31, the magnetic field formed in the stator 31 is subjected to electromagnetic interaction and the rotor 32 rotates, and the rotation shaft 33 also rotates at the same time. The connecting rod 35 connected to the lower end of the rotating shaft 33 performs a linear reciprocating motion through the rotational movement of the rotating shaft 33 to advance and retract the piston 22 to compress the refrigerant in the compression chamber 21a.
이때, 회전축(33)은 프레임(34)을 통해 회전 가능하게 지지되고, 회전자(32)는 프레임(34)의 상단에 지지되어 회전축(33)과 동시에 회전을 하게 되는데, 프레임(34)의 상단 및 회전자(32) 하부에는 각각 제 1마그네트(41)와, 제 2마그네트(42)가 설치된 상태이다. 이에 따라, 회전자(34)는 두 마그네트(41,42) 사이의 자기적 반발력에 의해 프레임(34)으로부터 소정거리 부상한 상태로 회전하게 되므로 프레임(34)과의 직접적인 마찰을 방지할 수 있게 된다.At this time, the rotating shaft 33 is rotatably supported through the frame 34, the rotor 32 is supported on the upper end of the frame 34 to rotate simultaneously with the rotating shaft 33, the frame 34 The first magnet 41 and the second magnet 42 are installed in the upper and lower rotor 32, respectively. Accordingly, the rotor 34 is rotated in a state of floating a predetermined distance from the frame 34 by the magnetic repulsive force between the two magnets (41, 42) to prevent direct friction with the frame (34) do.
이상에서 상세히 설명한 바와 같이, 본 발명에 따른 밀폐형 압축기는 프레임에 제 1마그네트가 설치되고, 회전자에 제 1마그네트와 동일 극성으로 마주보는 제 2마그네트가 설치된다.As described in detail above, in the hermetic compressor according to the present invention, a first magnet is installed in a frame, and a second magnet is installed in the rotor facing the same polarity as the first magnet.
이에 따라, 두 마그네트 사이의 자기적 반발력에 의해 회전자는 프레임으로부터 소정거리 부상한 상태로 회전하게 되므로 회전자 및 프레임 간의 직접적인 마찰을 방지할 수 있게 된다.Accordingly, the rotor is rotated in a state of floating a predetermined distance from the frame by the magnetic repulsive force between the two magnets it is possible to prevent direct friction between the rotor and the frame.
따라서, 회전자와 프레임 간의 마찰 소음이 억제되어 정숙한 압축기의 구동을 이룰 수 있게 되고, 회전자 및 프레임이 마찰에 의해 마모되는 것을 방지할 수 있게 되어 압축기의 수명을 연장할 수 있게 된다. Therefore, friction noise between the rotor and the frame can be suppressed to achieve a quiet driving of the compressor, and the rotor and the frame can be prevented from being worn by friction, thereby extending the life of the compressor.
또한, 회전자 및 프레임 사이의 마찰력을 완전히 해소시키게 되므로 압축기의 구동효율을 전체적으로 향상시킬 수 있게 되는 효과가 있다.In addition, since the friction between the rotor and the frame is completely eliminated, the driving efficiency of the compressor can be improved as a whole.
