본 고안은 냉장고등에 사용되는 밀폐형압축기의 피스톤과 커넥팅로드 및 실린더 등에 윤활유를 공급시켜주기 위한 밀폐형 압축기의 윤활장치에 관한 것이다.The present invention relates to a lubrication device of a hermetic compressor for supplying lubricating oil to pistons, connecting rods and cylinders of hermetic compressors used in refrigerators.
냉장고 등에 사용되는 왕복동식 밀폐형 압축기에 있어서, 모우터의 구동에 따른 회전운동력이 크랭크 샤프트 및 이에 연결된 커넥팅로드에 전달되면 피스톤이 실린더내부에서 왕복운동을 하면서 저압의 냉매가스를 고압으로 압축시켜주게 되는데, 이렇게 냉매가스를 압축시키는 과정에서 상기 각 부품들이 왕복 및 회전운동함에 따라, 또는 압축되어지는 냉매가스의 압력에 의하여 압축기를 구성하는 각 부품들에 무리한 힘이 가해져서 이들이 마모되거나 심한 경우 전단파괴되는 우려가 있고, 이를 방지하여 원활한 운전이 이루어지도록 해주는 것이 윤활장치인바, 종래에 사용되던 그 일반적인 형태는 제2도에서 도시한 바와 같이 모우터(도시되어 있지 않음)로부터 회전운동력을 전달받는 크랭크 샤프트(21)의 내부에 윤활유공급구멍(22)을 형성시키고, 이러한 크랭크샤프트(21)의 선단에 경사면이 갖추어져있는 한편, 외면에 깔때기 모양으로 된 윤활유픽업부(23)를 연결시켜 이를 밀폐용기의 내면하부에 고여있는 윤활유에 어느정도 잠겨지도록 한 상태에서 크랭크샤프트(21)를 고속회전 운동시켜주면, 상기 윤활유가 윤활유공급구멍(22)에 흡입되어 원심력에 의해 윤활유공급구멍(22) 상부로 통과한 다음 크랭크샤프트(21)와 커넥팅로드(24), 커넥팅로드(24)와 피스톤(25)과 실린더(29)사이의 마찰부에 이송되어져 윤활작용을 하게 되는데, 특히 커넥팅로드(24)와 피스톤(25), 피스톤(25)을 결합시켜주는 피스톤(26)의 형상이 그의 주면중앙부에 하나의 홈(27)이 형성된 형태로 되어 있어서, 이 홈(27)을 타고 윤활유가 이송되게 하므로서 커넥팅로드끝(28)까지 윤활유가 원활하게 공급되지 못할뿐아니라, 피스톤핀(26)의 전체에 골고루 급유가 이루어지지 못하게 되어 커넥팅로드(24)와 피스톤핀(26)의 접촉부위 및 피스톤 핀(26)과 피스톤(25)의 접촉부위가 심한 열과 함께 마모되어 피스톤핀(26)이 전단 파괴되는 문제점이 있었다.In the reciprocating hermetic compressor used in the refrigerator, when the rotational motion force driven by the motor is transmitted to the crank shaft and the connecting rod connected thereto, the piston reciprocates in the cylinder and compresses the refrigerant gas of low pressure to a high pressure. In this process of compressing the refrigerant gas, as each component reciprocates and rotates, or by the pressure of the refrigerant gas being compressed, an excessive force is applied to each component constituting the compressor so that they are worn or severely shear failure. The lubrication device is a lubrication device that prevents this and ensures smooth operation, and the general form used in the related art is a crank which receives a rotational motion force from a motor (not shown) as shown in FIG. Lubricating oil supply hole 22 is formed in the shaft 21 While the inclined surface is provided at the front end of the crankshaft 21, the crankshaft in a state in which the funnel-shaped lube oil pick-up part 23 is connected to the outer surface so as to be partially submerged in the lube accumulated in the lower surface of the sealed container. When the 21 is rotated at a high speed, the lubricating oil is sucked into the lubricating oil supply hole 22 and passed through the lubricating oil supply hole 22 by centrifugal force, followed by the crankshaft 21 and the connecting rod 24 and the connecting rod. It is transferred to the friction portion between the 24 and the piston 25 and the cylinder 29 to lubricate, in particular the piston 26 for coupling the connecting rod 24, the piston 25, the piston 25 Has a shape in which a groove 27 is formed in the center of the main surface thereof, so that the lubricant is not smoothly supplied to the connecting rod end 28 by allowing the lubricant to be transported through the groove 27, as well as the piston. pin( Since the oil is not evenly supplied to the entirety of the 26, the contact portion of the connecting rod 24 and the piston pin 26 and the contact portion of the piston pin 26 and the piston 25 are worn with severe heat and the piston pin 26 ) Has a problem that shear failure.
이에 본 고안은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 그 외주면 일부를 절삭가공하여 평면부를 형성시킨 피스톤핀을 일반적인 밀폐형압축기의 윤활장치의 피스톤과 커넥팅 로드사이에 결합시켜줌으로서, 상기 평면부를 따라 피스톤핀 전체와 커넥팅로드 끝구석 구석까지 원활하게 윤활유를 공급해 주도록 밀폐형압축기의 윤활장치를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, by coupling a piston pin formed by cutting a portion of the outer peripheral surface between the piston and the connecting rod of the lubrication device of a general hermetic compressor, Its purpose is to provide a lubrication device for hermetic compressors to smoothly supply lubricating oil to the entire piston pin and every corner of the connecting rod.
이하 첨부된 예시도면에 의거 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention will be described based on the accompanying drawings.
본 고안은 밀폐형압축기 내부의 깔때기형 윤활유픽업부(1)에 크랭크 샤프트(2)의 선단(3)이 끼워지게 설치하고, 상기 크랭크 샤프트(2)에 커넥팅로드(4)를 설치하되 상기 커넥팅로드(4)에는 피스톤핀(5)을 사용하여 피스톤(6)을 결합시킨 구조로 되어 있다.The present invention is installed so that the front end (3) of the crankshaft (2) is fitted to the funnel-type lubricating oil pickup (1) inside the hermetic compressor, and the connecting rod (4) is installed on the crankshaft (2), but the connecting rod (4) has a structure in which the piston 6 is engaged using the piston pin 5.
또한 상기 크랭크 샤프트(2)와 커넥팅로드(4)의 각각의 내부에는 상호 연통되도록 된 윤활유 공급통로(7,8)가 형성되어져 있고, 특히 상기 피스톤 핀(5)에는 그 외주면에 길이방향으로 평면부(9)가 형성되어져 있다.In addition, each of the crankshaft 2 and the connecting rod 4 is provided with lubricating oil supply passages 7 and 8 which are in communication with each other, and in particular, the piston pin 5 is planar in the longitudinal direction on its outer circumferential surface. The part 9 is formed.
도면중 미설명부호 10은 실린더, 11은 커넥팅로드끝이다.In the drawings, reference numeral 10 denotes a cylinder and 11 a connecting rod end.
이상과 같이 구성된 본 고안의 단면도가 제1도에 나타내어져 있는 바, 윤활유픽업부(1)를 밀폐용기내면 하부에 고여있는 윤활유속에 적절한 깊이로 잠겨지게 설치하고 모우터(도시되어 있지 않음)를 구동시켜주면, 크랭크샤프트(2)가 회전함에 따라 발생되는 원심력에 의하여 윤활유가 빨아올려져 크랭크샤프트(2)의 윤활유공급통로(7)및 커넥팅로드(4)의 윤활유공급통로(8)을 통해 피스톤(6)에 형성된 평면부(9)를 따라 피스톤 핀(5)둘레에 공급되어 피스톤(6)과 마찰되는 실린더(10)벽에 윤활작용을 해주는 한편, 상기 평면부(9)를 타고 넘은 윤활유가 커넥팅로드끝(11)의 구석구석에 까지 공급되어져 윤활작용을 하게된다.As shown in FIG. 1 is a cross-sectional view of the present invention configured as described above, the lube oil pick-up unit 1 is installed to be locked to an appropriate depth to the lube oil accumulated in the lower portion of the sealed container and the motor (not shown) is installed. When driven, the lubricating oil is sucked up by the centrifugal force generated as the crankshaft 2 rotates, and through the lubricating oil supply passage 7 of the crankshaft 2 and the lubricating oil supply passage 8 of the connecting rod 4. The circumference of the cylinder 10, which is supplied to the circumference of the piston pin 5 along the flat portion 9 formed in the piston 6 and rubs against the piston 6, is carried over the flat portion 9. Lubricant is supplied to every corner of the connecting rod end 11 to lubricate.
여기에서 피스톤(5)은 열과 압축에 의한 변형과 마모에 견딜수 있도록 특수강으로 제조되며, 커넥팅로드(4)의 재질은 일반적으로 강재를 사용하지만 강재대신 알미늄으로 하는 경우에도 상기 피스톤핀(5)의 평면부(9)를 따라 원활한 윤활작용이 이루어지도록 커넥팅로드(4)의 수명에는 별지장이 없게 된다.Here, the piston (5) is made of special steel to withstand deformation and wear caused by heat and compression, the material of the connecting rod (4) is generally made of steel, but in the case of aluminum instead of steel of the piston pin (5) The life of the connecting rod 4 is not affected so that smooth lubrication is performed along the flat portion 9.
상기한 바와같은 본 고안에 따른 본 고안에 따른 장치를 사용하므로서 밀폐형 압축기를 구성하는 각 요소들이 구석구석에까지 윤활유가 공급되게하여 커넥팅로드(4)와 피스톤(6), 피스톤(5)및 실린더(10)벽등의 수명을 연장시킬 수 있는 효과가 있다.By using the apparatus according to the present invention as described above, each element constituting the hermetic compressor is supplied with lubricating oil to every corner of the connecting rod (4), the piston (6), the piston (5) and the cylinder ( 10) It has the effect of extending the life of walls.
