Description
본 고안은 연소가스압에 의해 크랭크 축을 구동하는 피스톤기구에 관한 것이다.The present invention relates to a piston mechanism for driving the crankshaft by combustion gas pressure.
종래 피스톤기구는 도 3 에 도시하는 것과같이 피스톤(11)과 커넥팅로드(12)로 구성되어 있으며 커넥팅로드(12)는 피스톤 핀(13)에 의해 피스톤(11)과 연결되어 있다.The conventional piston mechanism is composed of a piston 11 and a connecting rod 12 as shown in FIG. 3, and the connecting rod 12 is connected to the piston 11 by a piston pin 13.
이에따라 상기 커넥팅로드(12)는 크랭크 축에 연결되는 대단부(14)와 피스톤 핀(13)에 지지되는 소단부(15)를 구비하며 소단부(15)와 피스톤 핀(13)은 원통면 접촉을 유지하므로 커넥팅로드(12)는 피스톤 핀(13)에 의해 구속되어 일방향의 움직임(피스톤 핀의 원주방향)만 허용된다.Accordingly, the connecting rod 12 has a large end portion 14 connected to the crank shaft and a small end portion 15 supported by the piston pin 13, and the small end portion 15 and the piston pin 13 are in cylindrical contact. Since the connecting rod 12 is constrained by the piston pin 13, only one direction of movement (circumferential direction of the piston pin) is allowed.
그러나 상기와 같이 피스톤 핀(13)에 의한 연결은 피스톤(11)의 왕복운동을 크랭크축의 회전운동으로 바꾸는 데에는 문제가 없으나 실린더보어와의 접촉은 트러스트(Thrust)측에 집중되어 스컷부(11a)의 마모가 집중되고 프런트사이드와 리어사이드는 트러스트와 앤티-트러스트에 비해 열을 많이 받기 때문에 국부적인 마모 및 과열현상이 일어나는 문제점이 지적되고 있다.However, as described above, the connection by the piston pin 13 has no problem in converting the reciprocating motion of the piston 11 into the rotational motion of the crankshaft, but the contact with the cylinder bore is concentrated on the thrust side and thus the cut portion 11a. The wear and tear of the front side and the front side and the heat side compared to the trust and anti-trust has been pointed out that the local wear and overheating occurs.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 피스톤이 왕복운동중에 원주방향으로 회전할 수 있도록 하므로써 국부적인 마모와 과열을 방지하여 내구성을 향상시킨 피스톤기구를 제공하는데 있다.The present invention has been proposed in view of the above problems, and its object is to provide a piston mechanism that improves durability by preventing local wear and overheating by allowing the piston to rotate in the circumferential direction during the reciprocating motion. .
상기한 목적을 달성하기 위한 본 고안은The present invention for achieving the above object

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 피스톤기구의 단면도로서 도면에 있어서 부호 1과 2는 각기 피스톤기구를 구성하는 피스톤과 커넥팅로드이다.1 is a cross-sectional view of the piston mechanism according to the present invention, in the drawings, reference numerals 1 and 2 are pistons and connecting rods respectively constituting the piston mechanism.
상기 커넥팅로드(2)의 일단은 크랭크 축에 연결되는 원통형 베어링부분인 대단부(3)가 형성되고 그의 타단은 구형(Ball 형상)의 소단부(4)로 형성되어 있다.One end of the connecting rod 2 is formed with a large end 3, which is a cylindrical bearing part connected to the crankshaft, and the other end thereof is formed with a spherical (Ball-shaped) small end 4.
피스톤(1)의 안쪽 저면(5)에 볼트(6)에 의해 고정되는 소켓(7)에는 상기 구형소단부(4)를 수용하여 360°전방향에 걸쳐 움직임이 허용되도록 구형요홈(8)이 형성되어 있으며 상기 구형소단부(4)를 수용할 수 있게 상기 소켓(7)은 2개의 몸체(7a)(7b)로 분할 제작된 후 각기 둥근머리 볼트(6)에 의해 피스톤(1) 상부로부터 너트(9)를 사용하여 체결고정한다.The socket 7 secured by the bolt 6 to the inner bottom 5 of the piston 1 has a spherical recess 8 for accommodating the spherical small end 4 so as to allow movement over 360 ° in all directions. And the socket 7 is divided into two bodies 7a and 7b so as to accommodate the spherical small end 4, and then each round head bolt 6 from the top of the piston 1 Fasten with nuts (9).
이에따라 커넥팅로드(2)는 크랭크 축 회전에 의해 좌우 일방향으로 요동하는 자유도를 가지는 것은 종래와 동일하나 피스톤(1)이 구형소단부(4)에 의해 원주방향으로 회전하는 자유도를 갖게 되므로써 피스톤의 마모가 균일하게 일어나고 특정부위에의 국부적인 과열현상이 없이 열부하가 고르게 분산되어지게 되는 것이다.Accordingly, the connecting rod 2 has the same degree of freedom in swinging in one direction in the left and right directions by the crank shaft rotation, but the piston 1 wears in the circumferential direction by the spherical small end portion 4. Is uniformly distributed and the heat load is evenly distributed without local overheating at a specific site.
이상과 같은 본 고안의 피스톤기구에 의하면 피스톤과 커넥팅로드가 구형소단부에 의해 결합되어 피스톤이 상하 왕복구동중 회전이 가능하여 트러스트부가 사실상 없어지게 되므로써 피스톤의 국부적인 마모 및 과열이 방지되어 피스톤의 내구성을 크게 향상시키게 되는 효과가 있다.According to the piston mechanism of the present invention as described above, the piston and the connecting rod are coupled by the spherical small end, so that the piston can rotate during up and down reciprocating operation, thereby virtually eliminating the thrust portion, thereby preventing the piston's local wear and overheating. There is an effect to greatly improve the durability.
