본 고안은 왕복동식 압축기의 압축장치에 관한 것으로서, 특히 실린더와 피스톤 사이의 피스톤 슬랩(piston slap)현상을 완충시켜 주기 위해 피스톤에 완충부를 부가한 것이다.The present invention relates to a compression device of a reciprocating compressor, and in particular, a shock absorbing part is added to a piston to cushion a piston slap phenomenon between a cylinder and a piston.
일반적으로 왕복동식 압축기는 제1도와 제2도에서 도시되는 바와 같이, 압축용기(1) 내부에서 프레임(2) 하부에 고정자(3)와 회전자(4)로 되는 전동부가 설치되고, 프레임(2) 상부에 실린더(6)에 피스톤(5)이 장착되는 압축장치가 설치되며, 회전자(4)와 연동하여 회전하는 크랭크축(7) 하단부에 급유장치(8)가 장치되어 있다.In general, as shown in FIG. 1 and FIG. 2, the reciprocating compressor includes a transmission unit including a stator 3 and a rotor 4 under the frame 2 in the compression container 1, and includes a frame ( 2) A compression device in which the piston 5 is mounted on the cylinder 6 is installed in the upper part, and an oil supply device 8 is provided at the lower end of the crankshaft 7 which rotates in conjunction with the rotor 4.
여기에서, 회전자(4) 중심부에 삽입되는 회전축은 크랭크축(7)과 일체로 형성되어, 크랭크축(7) 상단부에 슬라이드(9)가 회전가능하게 연결되고, 슬라이드(9)에 피스톤(5)이 연결되며, 피스톤(5)이 실린더(6) 내주면에 슬라이딩 가능하게 삽입되어 있다.Here, the rotating shaft inserted in the center of the rotor 4 is formed integrally with the crank shaft 7, the slide 9 is rotatably connected to the upper end of the crank shaft 7, the piston (9) 5) is connected, and the piston 5 is slidably inserted into the inner circumferential surface of the cylinder 6.
이와같이 구성되는 종래 왕복동식 압축기는 전원이 인가되면, 전동부의 회전자(4)에 일체로 연결되는 크랭크축(7)이 일체로 회전되고, 크랭크축(7)이 피스톤(5)을 왕복 작동시켜 냉매를 흡입 또는 압축하고, 동시에 급유장치(8)를 작동시켜 압축장치에 급유하게 된다. 또한, 회전되는 크랭크축(7)에 슬라이드(9)가 연결되어 회전 작동이 왕복작동으로 변환되고, 슬라이드(9)에 연결되는 피스톤(5)이 실린더(6) 내주면을 따라 왕복으로 작동한다.In the conventional reciprocating compressor configured as described above, when power is applied, the crankshaft 7 which is integrally connected to the rotor 4 of the electric drive unit is rotated integrally, and the crankshaft 7 reciprocates the piston 5. The refrigerant is sucked or compressed, and at the same time, the oil supply device 8 is operated to supply oil to the compression device. In addition, the slide 9 is connected to the rotating crankshaft 7 so that the rotational operation is converted to reciprocating operation, and the piston 5 connected to the slide 9 operates reciprocally along the inner circumferential surface of the cylinder 6.
이러한 종래 왕복동식 압축기는 피스톤(5)이 왕복으로 작동됨에 따라, 냉매가 실린더(6) 내부로 흡입되어 압축될 때, 불균형 질량 및 압력에 의해 피스톤(5)이 실린더(6) 내측벽에 충돌하는 피스톤 슬랩(slap)현상이 발생되고, 이로 인해 실린더(6)와 피스톤(5)이 마모되어 수명이 단축되는 결함이 있었다.In this conventional reciprocating compressor, as the piston 5 is operated reciprocally, when the refrigerant is sucked into the cylinder 6 and compressed, the piston 5 impinges on the inner wall of the cylinder 6 by an unbalanced mass and pressure. The piston slap phenomenon occurs, which causes the cylinder 6 and the piston 5 to wear, there was a defect that shorten the life.
본 고안의 목적은 상기와 같은 피스톤 슬랩현상을 완충시켜 마모를 줄여 주기 위해, 피스톤의 일측 단부에 완충부를 형성한 피스톤 슬랩 완충용 왕복동식 압축기의 압축장치를 제공하는데 있다.It is an object of the present invention to provide a compression device for a piston slap buffering reciprocating compressor having a shock absorbing portion formed at one end of a piston in order to cushion the piston slap phenomenon as described above and reduce wear.
이하 첨부된 도면에 따라 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.
제3도는 본 고안의 완충부가 부착된 피스톤의 구조를 나타내는 단면도이고, 제4도는 본 고안의 완충부가 부착된 피스톤이 크랭크축에 연결되어 실린더에 삽입된 상태를 나타내는 단면도로서, 실린더(6)에 일단부가 슬라이딩 가능하게 삽입되고 타단부가 슬라이드(9)에 연결되는 피스톤(5) 타단부 외주면에 완충부(10)가 부착됨을 그 특징으로 한다.3 is a cross-sectional view showing the structure of the piston with the shock absorbing portion of the present invention, Figure 4 is a cross-sectional view showing a state in which the piston with a shock absorbing portion of the present invention is connected to the crankshaft inserted into the cylinder, One end portion is slidably inserted, and the other end portion is characterized in that the shock absorbing portion 10 is attached to the outer peripheral surface of the other end of the piston 5 connected to the slide 9.
여기서, 본 고안의 완충부(10)는 완충재로 형성되어, 크랭크축(7)의 회전을 왕복작동으로 바꿔주는 슬라이드(9)에 연결되는 피스톤(5)의 외주면에 기밀하게 부착되어, 피스톤(5)이 실린더(6) 벽에 충돌할 때, 그 충격을 흡수하도록 하므로, 피스톤(5)이 마모되는 현상을 완화시켜준다.Here, the shock absorbing portion 10 of the present invention is formed of a shock absorbing material and is hermetically attached to the outer circumferential surface of the piston 5 connected to the slide 9 for changing the rotation of the crankshaft 7 to reciprocating operation. When 5) collides with the cylinder 6 wall, it absorbs the shock, thereby alleviating the phenomenon that the piston 5 wears.
한편, 제5도는 본 고안의 다른 실시예를 나타내는 단면도로서, 피스톤(5)의 외주면에 완충부(10)가 부착되고, 피스톤(5)이 삽입되는 실린더(6)의 측면부에 제2완충부(11)가 형성됨을 그 특징으로 한다.On the other hand, Figure 5 is a cross-sectional view showing another embodiment of the present invention, the shock absorbing portion 10 is attached to the outer peripheral surface of the piston 5, the second buffer portion in the side portion of the cylinder 6, the piston 5 is inserted It is characterized by the fact that (11) is formed.
이와같이 구성되는 본 고안은 전원이 인가되어, 피스톤이 실린더 내부를 왕복작동하고, 피스톤(5)의 왕복작동에 의해 냉매가 실린더(6) 내부로 흡입 및 압축될 때, 불균형 질량 및 압력에 피스톤 슬랩(slap)현상이 발생될 경우, 완충부(10)가 진동과 충격을 흡수하여, 충격의 파장을 줄여준다.The present invention constituted as described above has a piston slap with an unbalanced mass and pressure when power is applied to the piston to reciprocate the inside of the cylinder and the refrigerant is sucked into and compressed into the cylinder 6 by the reciprocating action of the piston 5. When a slap phenomenon occurs, the buffer unit 10 absorbs vibration and shock, thereby reducing the wavelength of the shock.
따라서, 이러한 본 고안은 작동중 피스톤(5)이 실린더(6) 내측벽에 부딪치는 피스톤 슬랩현상시 완충부(10)가 충격과 진동을 흡수하여 주므로, 실린더(6)와 피스톤(5)이 마모되는 것을 줄여주어, 수명을 연장시켜주는 효과가 있다.Therefore, this invention devises that the shock absorbing portion 10 absorbs shock and vibration when the piston 5 hits the inner wall of the cylinder 6 during operation, and thus the cylinder 6 and the piston 5 Reduces wear and extends life.
이상에서 살펴본 바와같이, 본 고안은 피스톤 일측 단부의 외주면에 완충부를 형성하여, 피스톤 슬랩현상을 완충시켜주므로, 마모를 줄여주어 수명을 연장시켜주는 매우 유용한 것이다.As described above, the present invention is to form a shock absorbing portion on the outer peripheral surface of the piston one end portion, so as to buffer the piston slap phenomenon, it is very useful to reduce the wear to extend the life.
