Description
본 고안은 커넥팅로드의 오일구멍 형성구조에 관한 것으로서,커넥팅로드의 대단부와 소단부를 연통하는 오일구멍을 형성하여 피스톤의 윤활을 효과적으로 하도록 한 커넥팅로드의 오일구멍 형성구조에 관한 것이다.The present invention relates to an oil hole forming structure of a connecting rod, and relates to an oil hole forming structure of a connecting rod for forming an oil hole communicating with a large end portion and a small end portion of a connecting rod to effectively lubricate a piston.
일반적으로 커넥팅로드는 그 소단부가 피스톤과 연결되고, 그 대단부가 크랭크핀에 연결되어 이들과 접동운동을 하게 되므로 이 접동부에 오일을 공급하여 윤활과 냉각을 하고 있다.In general, the connecting rod has a small end connected to the piston, and a large end thereof is connected to the crank pin to make sliding motion with them, thereby supplying oil to the sliding part to lubricate and cool.
즉, 통상의 비산 압송방식의 윤활방식을 택하고 있는 내연기관에 있어서, 상기 커넥팅로드의 대단부와 크랭크핀 사이는 주로 크랭크축 메인저어널에서 상기 크랭크핀저어널로 뚫린 오일통로로 유입되는 윤활유에 의해서 윤활되며, 상기 커넥팅로드 소단부와 피스톤의 접동부는 크랭크축이 회전하면서 비산되는 윤활유에 의해 대부분 윤활된다.That is, in an internal combustion engine employing a lubrication method of a conventional scattering pumping method, the lubricating oil flowing into the oil passage opened by the crank pin journal mainly from the crankshaft main journal between the large end of the connecting rod and the crank pin. It is lubricated by, and the connecting rod small end and the sliding part of the piston are mostly lubricated by lubricating oil splashed while the crankshaft rotates.
첨부된 도면 도 1에는 이와 같은 커넥팅로드와 피스톤이 결합된 상태를 나타낸 것으로서, 커넥팅로드(2)는 크랭크핀(10)과 연결되는 대단부(4)와, 이에 연장된 생크(6) 및 도시되지는 않았지만 피스톤(12)의 피스톤핀(14)과 연결되는 소단부로 이루어지게 된다.1 is a view illustrating a state in which the connecting rod and the piston are coupled to each other, the connecting rod 2 includes a large end portion 4 connected to the crank pin 10, an extended shank 6, and Although not made is made of a small end connected to the piston pin 14 of the piston 12.
특히, 상기 대단부(4)에는 상향한 오일구멍(8)이 형성되어 있는데, 이는 크랭크핀(10)이 회전할때 커넥팅로드(2)의 대단부(4)와의 펌핑작용으로 크랭크축의 메인저어널로부터 크랭크핀(10)으로 공급되는 오일이 상향하여 비산되도록 하여 크랭크축 및 상기 커넥팅로드(2)의 오일비산에 보조하여 피스톤(12)측의 윤활과 냉각을 하도록 되어 있는 것이다.In particular, the upper end portion 4 is formed with an upward oil hole 8, which is the main stir of the crankshaft by the pumping action with the large end portion 4 of the connecting rod 2 when the crank pin 10 rotates. The oil supplied from the null to the crank pin 10 is scattered upward to assist the crankshaft and oil scattering of the connecting rod 2 to lubricate and cool the piston 12 side.
물론 이때, 실린더벽은 상기 크랭크축과 커넥팅로드(2)의 오일비산작용으로 윤활이 이루어지게 되어 있었다.Of course, at this time, the cylinder wall was lubricated by the oil splash action of the crankshaft and the connecting rod (2).
그러나, 상기와 같이 커넥팅로드(2)의 대단부로부터 상향하여 형성된 오일구멍(8)으로부터 상기 피스톤(12) 까지의 거리가 너무멀어 비산되는 오일중의 대부분이 중간에서 낙하하게 되어 피스톤(12)의 접동부를 효율적으로 윤활하지 못하는 문제가 있었다.However, the distance from the oil hole 8 formed upwardly from the large end of the connecting rod 2 to the piston 12 is so far that most of the oil which is scattered falls in the middle of the piston 12. There was a problem of not lubricating the sliding portion efficiently.
본 고안은 상기와 같은 점을 감안하여 안출된 것으로서, 상기 오일구멍을 커넥팅로드의 대단부로부터 소단부에 이르도록 길게 형성하여 피스톤에 근접한 곳에서 오일을 분사시킴으써, 피스톤과 그 접동부를 효과적으로 윤활시키도록 하도록 하는데 그 목적이 있다.The present invention is conceived in view of the above, by forming the oil hole long from the large end to the small end of the connecting rod to inject the oil in the vicinity of the piston, the piston and its sliding portion effectively The purpose is to lubricate.
상기와 같은 목적을 달성하기 위한 본 고안은 커넥팅로드에 피스톤의 윤활을 위해 오일구멍을 형성하는데 있어서, 상기 커넥팅로드의 대단부로부터 소단부에 이르며, 피스톤의 내측에 오일을 공급하도록 하는 긴 오일구멍을 형성한 것을 특징으로 하는 커넥팅로드의 오일구멍 형성구조를 제공한다.The present invention for achieving the above object is to form an oil hole for lubrication of the piston in the connecting rod, from the large end to the small end of the connecting rod, the long oil hole to supply oil to the inside of the piston It provides an oil hole forming structure of the connecting rod, characterized in that formed.

이하 본 고안의 바람직한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.
도 2는 도시된 바와 같이 본 고안에 따라 커넥팅로드에 구멍이 형성된 상태를 나타내는 것으로서, 커넥팅로드(2)의 대단부(4)로부터 생크(6)를 지나 소단부에 이르는 긴 오일구멍(20)이 형성된다.2 shows a state in which a hole is formed in the connecting rod according to the present invention as shown, and the long oil hole 20 extending from the large end 4 of the connecting rod 2 to the small end through the shank 6. Is formed.
상기 오일구멍(20)은 커넥팅로드(2)의 대단부(4)로부터 직선상으로 출발하여 그 소단부에 이르어서는 양측으로 굴곡되어 피스톤(12)의 내측에 근접한 부분에서 오일이 공급되도록 한 것이다.The oil hole 20 starts straight from the large end portion 4 of the connecting rod 2 and is bent to both sides to reach the small end portion thereof so that oil is supplied from a portion close to the inner side of the piston 12. will be.
한편, 상기한 오일구멍(20)을 형성함에 있어서는, 대단부(4)로부터 소단부측으로 일종의 건드릴( Gun Drill)로 직선상의 오일구멍(20)을 형성하고, 이후 소단부의 양방향으로부터 상기 직선상의 오일구멍(20)과 연통되는 오일구멍(20)을 재차 형성하는 방법도 있다.On the other hand, in forming the above-mentioned oil hole 20, a straight oil hole 20 is formed by a kind of gun drill from the large end portion 4 to the small end side, and then the linear shape is formed from both ends of the small end portion. There is also a method of forming the oil hole 20 in communication with the oil hole 20 again.
본 고안의 오일구멍(20)은 상기와 같은 구조로 되어 있기 때문에 크랭크축이 회전하면 상기 크랭크축의 메인저어널로부터 소정의 오일구멍(20)을 통하여 상기 크랭크핀(10)에 오일이 공급된다.Since the oil hole 20 of the present invention has the structure as described above, when the crank shaft rotates, oil is supplied to the crank pin 10 from the main journal of the crank shaft through a predetermined oil hole 20.
이 오일은 커넥팅로드(2)와 크랭크핀(10)의 측면틈새로 유입되는 오일과 합쳐져서 크랭크가 상향회전할 시 크랭크핀(10)과 커넥팅로드(2)의 대단부(4) 사이의 갭(Gap)이 줄어드는 펌핑작용에 의해서 상향하는 상기 오일구멍(20)으로 분사된다.This oil is combined with the oil flowing into the side gap of the connecting rod 2 and the crank pin 10 so that the gap between the crank pin 10 and the large end 4 of the connecting rod 2 when the crank is rotated upward ( Gap) is injected into the oil hole 20 upward by a reducing pumping action.
이와 같이 오일구멍(20)을 상향하여 분사되는 오일은 상기 피스톤(12)의 내측에 분사되게 되어 피스톤(12)의 윤활을 돕는 것이다.In this way, the oil injected upwards of the oil hole 20 is injected into the piston 12 to help lubrication of the piston 12.
이때, 상기 오일구멍(20)은 상기 피스톤(12)에 근접한 곳까지 형성되어 있으므로 중간에 오일손실 없이 대부분의 오일이 피스톤(12)에 공급되므로 효과적으로 윤활하게 되는 것이다.At this time, since the oil hole 20 is formed to be close to the piston 12, most oil is supplied to the piston 12 without oil loss in the middle, thereby effectively lubricating.
상술한 바와 같이 본 고안의 커넥팅로드의 오일구멍 형상구조는 오일구멍을 대단부로부터 소단부에 이르도록 길게 형성하여 피스톤에 근접한 곳까지 오일을 분사시킴으로써, 오일구멍으로부터 상기 피스톤까지의 거리가 가까워 비산되는 오일이 피스톤의 접동부를 효율적으로 윤활하는 효과가 있다.As described above, the oil hole-shaped structure of the connecting rod of the present invention is formed by extending the oil hole from the large end to the small end and injecting oil to the position close to the piston, so that the distance from the oil hole to the piston is scattered. The oil to be effectively lubricated the sliding part of the piston.
