Description
본원 고안은 크랭크축의 밸런싱웨이트에 균형유지를 위해 보조웨이트를 설치하게 될때 보조웨이트와의 간섭을 방지하는 구조의 커넥팅로드에 관한 것이다.The present invention relates to a connecting rod having a structure for preventing interference with the auxiliary weight when the auxiliary weight is installed to maintain the balance on the balancing weight of the crankshaft.
크랭크축은 진동이 없이 원활하게 회전할 필요가 있으나 크랭크 저널중심과 크랭크핀 중심은 편심되어 있으므로 그대로 회전시키면 밸런스를 유지할 수 없게된다. 따라서 크랭크핀의 반대쪽의 크랭크암에 밸런싱웨이트를 설치하여 회전중에 밸런스를 유지하게 되며 통상 소형 엔진에서는 크랭크축과 밸런싱웨이트를 일체로 제작하고 있다.The crankshaft needs to rotate smoothly without vibration, but the crank journal center and the crankpin center are eccentric. Therefore, a balancing weight is installed on the crank arm opposite to the crank pin to maintain balance during rotation. In a small engine, a crank shaft and a balancing weight are manufactured integrally.
그러나 밸런싱의 불평형 위치가 밸런싱웨이트쪽이 아니고 정반대인 크랭크핀쪽일때 이를 극복하기 위한 방안으로 도 3에서와 같이 밸런싱웨이트(2)에 별도의 보조(부가)웨이트(4)를 장착하는 일이 있게된다.However, when the unbalanced position of the balancing is not the balancing weight side but the opposite crank pin side, a separate auxiliary (4) weight 4 may be mounted on the balancing weight 2 as a way to overcome this. .
그러나 상기한 구조의 경우 크랭크축(1)과 피스톤(5)을 연결하는 커넥팅로드(6)가 하사점(BDC) 상태에 이를때 돌출된 보조웨이트(4)와의 간섭으로 크랭크축 설계에 여러가지 공간적 제약이 발생하는 문제점이 지적되고 있다.However, in the case of the above structure, when the connecting rod 6 connecting the crankshaft 1 and the piston 5 reaches the bottom dead center (BDC) state, the space between the crankshaft design and the auxiliary weight 4 protrudes. The problem of constraints is pointed out.
이에 본원 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 크랭크축의 밸런싱 웨이트에 보조웨이트를 장착시 간섭을 극복할 수 있는 구조의 컨넥팅로드를 제공하는데 있다.The present invention has been proposed in view of the above problems, and its object is to provide a connecting rod having a structure capable of overcoming interference when mounting an auxiliary weight on a balancing weight of a crankshaft.
상기한 목적을 달성하기 위한 본원 고안은The present invention for achieving the above object
크랭크축의 밸런싱웨이트에 보조웨이트가 설치된 밸런스유지 구조에 있어서,In the balance maintenance structure in which the auxiliary weight is installed on the balancing weight of the crankshaft,
상기 크랭크축과 피스톤을 연결하는 커넥팅로드의 생크부는 피스톤의 중심축을 기준하여 상기 보조웨이트의 반대측으로 편심되어 있는 것임을 고안의 요지로 하고있다.The shank portion of the connecting rod connecting the crankshaft and the piston is intended to be eccentric to the opposite side of the auxiliary weight with respect to the central axis of the piston.

이하 본 고안의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 고안의 크랭크축과 커넥팅로드의 전체형상도이며1 is an overall view of the crankshaft and connecting rod of the present invention
도 2는 본 고안 커넥팅로드의 정단면도이다.2 is a front sectional view of the connecting rod of the present invention.
도면중 부호 1은 크랭크축이며 부호 2는 크랭크축(1)의 균형을 유지하기 위한 밸런싱웨이트이다.In the figure, reference numeral 1 denotes a crankshaft, and reference numeral 2 denotes a balancing weight for maintaining balance of the crankshaft 1.
상기 밸런싱웨이트(2)의 크랭크핀(3)의 대향 위치에는 불균형위치가 크랭크핀(3) 쪽일때 균형을 잡기위하여 보조웨이트(4)가 돌출되어 있다.In the opposite position of the crank pin 3 of the balancing weight 2, the auxiliary weight 4 protrudes to balance when the imbalance position is the crank pin 3 side.
상기 크랭크핀(3)과 피스톤(5)은 커넥팅로드(6)에 의해 연결되며 상기 커넥팅로드(6)의 피스톤(5)에 접속되는 소단부(7)와, 크랭크핀(3)에 끼워지는 대단부(8) 사이를 일체로 연결하는 생크부(Shank, 9)는 상기 피스톤(5)의 중심축선상을 기준하여 상기 보조웨이트(4)의 반대측으로 편심(e)되어 있다.The crank pin (3) and the piston (5) is connected by a connecting rod (6) and the small end (7) connected to the piston (5) of the connecting rod (6), which is fitted to the crank pin (3) Shank 9, which integrally connects the large ends 8, is eccentrically e opposite to the auxiliary weight 4 with respect to the center axis line of the piston 5.
이에따라 생크부(9)와 중심축선(A-A)과의 사이에는 편심량(e) 만큼의 공간이 존재하게 되어 피스톤(5)이 하사점에 다다를때 보조웨이트(4)가 생크부(9)에 간섭되지 않게 되는 것이다.As a result, a space equal to the amount of eccentricity e exists between the shank portion 9 and the central axis AA so that the auxiliary weight 4 interferes with the shank portion 9 when the piston 5 reaches the bottom dead center. It will not be.
이상과 같은 본원 고안의 커넥팅로드에 의하면 크랭크축의 밸런싱의 불평형위치가 밸런싱웨이트쪽이 아니고 정반대편인 크랭크핀에 있어 이를 해소하기 위한 방안으로 보조웨이트를 밸런싱웨이트에 마련하고 있는 크랭크축의 경우 커넥팅로드의 생크부를 부가웨이트의 일측(부가웨이트의 반대측)으로 편심시켜 제작하므로써 보조웨이트에 의한 간섭을 방지하여 크랭크기구의 구조적 제약을 해결하게 되는 효과가 있다.According to the connecting rod of the present invention as described above, in the case of the crank shaft having the auxiliary weight in the balancing weight as a way to solve the crank pin, the counterbalance position of the crank shaft is not on the balancing weight side but on the opposite side. By producing the shank portion on one side of the additional weight (the opposite side of the additional weight), there is an effect of solving the structural constraints of the crank mechanism by preventing interference by the auxiliary weight.
