본 고안은 횡형 로타리 콤프레서의 급유 및 방진장치, 더 상세히는 자체 진동을 흡수하는 진동 흡수장치를 이용한 급유 및 방진장치에 관한 것이다.The present invention relates to a lubrication and dustproof device for a horizontal rotary compressor, and more particularly, to a lubrication and dustproof device using a vibration absorber that absorbs its own vibration.

횡형 로타리 콤프레서는 케이싱(1)내부에 설치된 고정자(2)와 상대회전하는 회전자(3)에 결합된 크랭크축(4)이, 실린더 캡(7)내에 형성된 실린더(6)에 대해 롤러(8)를 편심 회전시킴으로써 압축을 행하도록 구성되어 있는데, 크랭크축(4)과, 롤러(8)등 미끄럼 운동부에 윤활유를 공급하기 위해 크랭크축(4)의 내부에는 윤활유 공급을 위한 내부 급유관(15) 및 급유 구멍(9)이 형성되어 있다.The horizontal rotary compressor has a roller (8) with respect to a cylinder (6) formed in a cylinder cap (7) with a crankshaft (4) coupled to a stator (2) provided in the casing (1) and a rotor (3) of relative rotation. ) Is configured to perform compression by eccentric rotation. An internal oil supply pipe 15 for supplying lubricant is provided inside the crankshaft 4 so as to supply lubricant to the crankshaft 4 and sliding parts such as the roller 8. ) And the oil supply hole 9 are formed.

그러나, 이러한 횡형 로타리 콤프레서는 옆으로 뉘어 설치되어 있으므로 윤활유(5)가 고인 레벨과 내부 급유관(15)사이에는 상당한 높이차이가 있으므로 윤활유(5)를 내부 급유관(15)까지 압상시키는 별도의 장치가 필요하였다.However, since the horizontal rotary compressor is installed side by side, there is a considerable height difference between the level of the lubricating oil 5 between the deceased level and the internal lubricating pipe 15, so that the lubricating oil 5 is pushed up to the internal lubricating pipe 15. An apparatus was needed.

이와는 별개로 횡형 로타리 콤프레서는 롤러(8)가 편심 회전하고 있으므로 크랭크축(4)에 수직인 방향으로 진동이 매우 크게 발생하는 문제점이 있었다.Apart from this, the horizontal rotary compressor has a problem in that the vibration is very large in the direction perpendicular to the crankshaft 4 because the roller 8 is eccentrically rotated.

본 고안은 이와 같은 진동을 적극적으로 이용하여 급유를 하는 동시에 진동을 감쇠시키고자 하는 것인바, 이하 첨부 도면에 의거 상세히 설명한다.The present invention intends to attenuate the vibration while lubricating the fuel by actively using such a vibration, which will be described in detail with reference to the accompanying drawings.

본 고안은 급유 방진장치는 크랭크축(4)과 미끄럼 접촉하여 내부 급유관(4)과 연결되는 급유관(10), 하부가 윤활유(5)내에 잠겨 유입구(16)을 통해 연통되는 급유 실린더(14)와, 케이싱(1)에 고정된 스프링(13)으로 지지되어 급유 실린더(14)내부에 미끄럼 운동 가능하게 수납된 진동피스톤(12), 급유관(10)의 내부에 설치된 유체 정류기(11)로 구성된다.In the present invention, the oil-proof dustproof device is an oil supply pipe 10 which is in sliding contact with the crankshaft 4 and connected to the internal oil supply pipe 4, and an oil supply cylinder in which the lower part is locked in the lubricating oil 5 and communicated through the inlet 16 ( 14 and a vibrating piston 12 supported by a spring 13 fixed to the casing 1 and slidably accommodated in the oil supply cylinder 14 and a fluid rectifier 11 installed inside the oil supply pipe 10. It is composed of

유체 정류기(11)는 압상시킨 유체의 역류를 방지하기 위한 것이므로 유체 압상시의 저항보다 역류시의 저항이 크도록 한 오리피스(orifice)나 또는 밸브판으로 구성되며 유입구(16)에도 필요에 따라 밸브판을 부착할 수 있다.Since the fluid rectifier 11 is for preventing the back flow of the pressurized fluid, the fluid rectifier 11 is composed of an orifice or a valve plate which has a greater resistance at the time of backflow than the resistance at the time of fluid compression. A plate can be attached.

이와 같은 구성의 본 고안 급유 및 방진장치는 다음과 같이 작동된다.The invention oil supply and dustproof device of such a configuration is operated as follows.

즉, 크랭크축(4)의 회전에 따라 축 직각방향으로 콤프레서가 진동하게 되면 이 진동은 스프링(13)을 통해 진동피스톤(12)에 전달되는데, 진동피스톤(12) 및 스프링(13)의 고유진동수를 콤프레서의 회전수의 약 0.8 내지 1.2배가 되도록 하면 진동피스톤(12)은 콤프레서의 진동에 대해 공진(resonance)하게 된다.That is, when the compressor vibrates in the direction perpendicular to the axis according to the rotation of the crankshaft 4, the vibration is transmitted to the vibration piston 12 through the spring 13, which is intrinsic to the vibration piston 12 and the spring 13. When the frequency is set to about 0.8 to 1.2 times the rotation speed of the compressor, the vibration piston 12 resonates with the vibration of the compressor.

이에 따라 콤프레서의 진동 에너지는 대부분 진동피스톤(12)의 진동 에너지로 변환되어, 진동피스톤(12)의 진폭은 커지나 콤프레서 자체의 진동은 감소하게 된다.Accordingly, the vibration energy of the compressor is mostly converted into the vibration energy of the vibration piston 12, so that the amplitude of the vibration piston 12 increases, but the vibration of the compressor itself is reduced.

또, 진동피스톤(12)의 상하 이동에 따라 급유실린더(14)의 내부용적이 증감되며 유입구(16)를 통해 유입된 윤활유(5)를 급유관을 통해 크랭크축(4)의 내부 급유관(15)으로 압상시키게 된다.In addition, as the vibration piston 12 moves up and down, the internal volume of the oil supply cylinder 14 increases and decreases, and the internal oil supply pipe of the crankshaft 4 receives the lubricant 5 introduced through the inlet 16 through the oil supply pipe ( 15).

이때 유체 정류기(11)는 진동피스톤(12)의 상승중에 윤활유의 역류를 방지하게 된다.At this time, the fluid rectifier 11 prevents the backflow of the lubricating oil while the vibration piston 12 is raised.

이상과 같이 본 고안 급유 및 방진장치는 콤프레서의 진동을 이용하여 급유를 함으로써 별도의 급유장치가 불필요할뿐 아니라, 진동을 흡수하여 진동 및 소음을 감소시킬수 있어서, 경제적이고 쾌적한 사용환경을 제공할 수 있다.As described above, the oil supply and vibration isolation device of the present invention not only eliminates the need for a separate oil supply device by supplying oil by using the vibration of the compressor, but also absorbs the vibration to reduce vibration and noise, thereby providing an economical and pleasant use environment. have.
