Description
본원 고안은 진동저감형 크랭크 축에 관한 것이다.The present invention relates to a vibration reduction crankshaft.
크랭크 축은 크랭크 케이스내에 설치된 베어링으로 지지되며 각 실린더의 팽창 행정으로 얻어진 직선적 동력을 커넥팅 로드를 통해서 회전력으로 바꾸어주는 것으로서 그의 구조는 도 3에 도시하는 것과 같이 크랭크 핀(10), 크랭크 저널부(11), 크랭크 핀과 저널부를 연결하는 크랭크 암(12) 및 회전 밸런스를 유지하기 위해 크랭크 암(12)에 일체로 형성되는 밸런싱 웨이트(13)를 구성되어 있다.The crankshaft is supported by a bearing installed in the crankcase and converts the linear power obtained by the expansion stroke of each cylinder into the rotational force through the connecting rod, the structure of which is shown in FIG. 3. The crank pin 10 and the crank journal part 11 ), A crank arm 12 connecting the crank pin and the journal portion, and a balancing weight 13 formed integrally with the crank arm 12 to maintain rotational balance.
상기한 바와 같은 종래구조에 의하면 밸런싱웨이트(13)가 주물 또는 단조성형에 의해 크랭크 암(12)과 일체로 형성되어 회전에 따른 밸런스를 유지하게 되나 관성력이 큰 밸런싱 웨이트(13)의 진동이 곧바로 크랭크 축에 전달되므로 진동 저감 능력이 떨어진다는 문제점이 지적되고 있다.According to the conventional structure as described above, the balancing weight 13 is formed integrally with the crank arm 12 by casting or forging molding to maintain the balance according to rotation, but the vibration of the balancing weight 13 with a large inertia force is immediately The problem is pointed out that the vibration reduction ability is transmitted because it is transmitted to the crankshaft.
이에 본 고안은 상기한 문제점을 해소하기 위해 안출한 것으로서 그의 목적으로하는 바는 밸런싱 웨이트를 밸개체로 형성하여 완충재를 개재시켜 크랭크 암에 조립시켜 진동을 흡수하는 구조의 크랭크 축을 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and its object is to provide a crankshaft of a structure that absorbs vibration by assembling a crank arm through a cushioning material by forming a balancing weight as a balancing member.

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 고안에 의한 크랭크 축의 측단면도로서 도면중 부호 1은 크랭크 축을 나타내며, 단 부호 2는 베어링에 의해 지지되는 저널부(2)이다.1 is a side cross-sectional view of a crankshaft according to the present invention, in which 1 denotes a crankshaft, and 2 denotes a journal portion 2 supported by a bearing.
상기 저널부(2)에는 피스톤 핀(3)과를 연결하는 크랭크 암(4)이 일체로 형성되며 크랭크 핀(3)의 반대쪽의 크랭크 암(4)의 끝단에는 부가 질량체(5, Counter Weight 또는 Balancing Weight)가 볼트(6)에 의해 나사 체결되어 있다.The journal portion 2 is integrally formed with a crank arm 4 connecting the piston pin 3 and an end mass of the crank arm 4 opposite the crank pin 3. Balancing Weight) is screwed by the bolt 6.
그리고 상기 부가 질량체(5)와 크랭크 암(4)과의 접촉면에는 진동이나 충격을 흡수할 수 있는 고무재질의 러버탄성체(7)가 개재되며 볼트(6)의 외주면에는 원통형의 절연접관(8, Insulated Collar)이 끼워져 있다.In addition, a rubber elastic body 7 of rubber material capable of absorbing vibration or shock is interposed on the contact surface between the additional mass 5 and the crank arm 4, and a cylindrical insulating weld tube 8 is formed on the outer circumferential surface of the bolt 6. Insulated Collar is inserted.
상기한 구조는 도 2의 개략도에서 나타낸 바와 같이 부가 질량체(5)가 크랭크축(1)에 대하여 스프링(9)(즉 본 고안 실시예에서는 러버탄성체 및 절연접관)으로 결합된 것으로 표현될 수 있으며 이는 부가 질량계라고 하는 동역학의 한 시스템으로서 진동저감 효과가 있게 된다.As shown in the schematic diagram of FIG. 2, the additional mass 5 may be expressed as a spring 9 (ie, a rubber elastic body and an insulation tube in the present embodiment) with respect to the crankshaft 1. This is a system of dynamics called an additive mass meter that has an effect of reducing vibration.
이상과 같은 본원 고안의 크랭크 축에 의하면 별개로 형성된 부가 질량체(Counter Weight)를 크랭크 암에 러버탄성체와 절연접관을 개재하여 볼트 체결함으로써 고속 회전시 부가 질량체의 높은 관성에 의한 진동을 러버탄성체와 절연접관이 차관하게 되크로 크랭크 축의 진동이 저감되는 효과가 있게된다.According to the crankshaft of the present invention as described above, the additional weight formed separately is bolted to the crank arm through the rubber elastic body and the insulated pipe, so that the vibration due to the high inertia of the additional mass is insulated from the rubber elastic body during high-speed rotation. As a result of the clearance, the vibration of the crankshaft is reduced.
