Description
본 고안은 피스톤과 커넥팅 로드의 계합구조 개선에 관한 것이다.The present invention is directed to improving the engagement structure of the piston and the connecting rod.
커넥팅 로드는 피스톤의 왕복 직선 운동을 크랭크축의 회전운동으로 전달해주는 기구로서 종래의 경우 제3도에 도시하는 것과 같이 피스톤 핀(20)에 소단부(21)가 계합되어 한방향으로의 움직임이 허용되도록 되어있다.The connecting rod is a mechanism that transmits the reciprocating linear motion of the piston to the rotational motion of the crankshaft, so that the small end 21 is engaged with the piston pin 20 to allow movement in one direction as shown in FIG. It is.
그러나 상기한 경우 피스톤 핀(20)이 중공파이프로 형성되어 있어 피스톤(22)의 보스부(23)에 구멍을 뚫은 후 피스톤 핀(20)을 박아넣어 조립하여야 하기때문에 피스톤 핀(20)의 장착시 조립불량 또는 오일 홈으로 불순물이 유입되어 빠져나오지 못하게 되므로써 마모의 원인이 되며 특히 피스톤(22)이 압축행정시 신기의 흐름에 의해 피스톤은 회전하려고 하나 커넥팅 로드(24)와의 계합구조상 회전이 되지 아니하므로 신기의 와류 형성에 방해가 되는 문제점이 지적되고 있다.However, in the case described above, since the piston pin 20 is formed of a hollow pipe, the piston pin 20 should be driven by assembling after drilling a hole in the boss portion 23 of the piston 22. When the piston 22 is trying to rotate by the flow of the wearer during the compression stroke, the piston 22 tries to rotate but does not rotate due to the engagement structure of the connecting rod 24. No, it is pointed out that the problem that hinders the formation of vortex vortex.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 피스톤과 커넥팅 로드의 조립이 쉬우며 피스톤이 힘을 받는대로 자유로이 회전할 수 있도록 한 피스톤과 커넥팅 로드의 계합구조를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above problems, and its purpose is to provide an engagement structure of the piston and the connecting rod that allows the piston and the connecting rod to be easily assembled and to allow the piston to rotate freely as the force is applied. There is.
상기한 목적을 달성하기 위하여 본 고안은 내면 중앙하부로 구형돌기가 돌출된 피스톤과; 상기 구형돌기를 수용하는 소단부를 반구형 요홈을 갖는 2개의 분할편으로 분리 성형한 후 상기 구형돌기의 표면에 양측으로부터 분할편을 밀착시켜 플랜지 체결하는 커넥팅 로드와; 로 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a piston having a spherical protrusion protruding from the inner bottom of the center; A connecting rod for separately forming a small end portion accommodating the spherical protrusion into two divided pieces having a hemispherical groove, and then flange-fitting the fragment piece from both sides to the surface of the spherical protrusion; Characterized in that consists of.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
제1도는 본 고안에 의한 피스톤과 커넥팅로드의 계합구조를 나타내는 도면이며, 제2도는 제1도의 A-A단면도이다.1 is a view showing the engagement structure of the piston and the connecting rod according to the present invention, Figure 2 is a cross-sectional view A-A of FIG.
도면중 부호 1은 피스톤이며 피스톤(1)의 내면 중앙에는 하부로 구형돌기(2)가 돌출되어 있다.In the drawing, reference numeral 1 denotes a piston, and a spherical protrusion 2 protrudes downward in the center of the inner surface of the piston 1.
상기 구형돌기(2)는 종래의 피스톤 핀의 역할을 하는 것으로서 커넥팅로드(3)의 소단부(4)에 계합된다.The spherical protrusion 2 is engaged with the small end 4 of the connecting rod 3 as serving as a conventional piston pin.
상기 소단부(4)는 2개의 분할편(5)(6)으로 형성되며 일측 분할편(5)은 커넥팅로드(3) 본체에 일체로 성형되고 타측분할편(6)은 별개체로 형성된 후 양측 플랜지(7)(8)를 맞대고 볼트(9) 체결한다.The small end portion 4 is formed of two divided pieces 5 and 6, one side piece 5 is integrally formed in the connecting rod 3 main body and the other side piece 6 is formed as a separate body. Tighten the bolts (9) by opposing the two flanges (7) and (8).
상기 양측 분할편(5)(6)에는 상기 구형돌기(2)를 수용할 수 있는 반구형요홈(10)(11)이 각기 형성되어 있으며 조립시에 양측 분할편(5)(6)의 반구형 요홈(10)(11)을 피스톤(1)의 구형돌기(2)의 양측에서 맞대어 플랜지(7)(8)를 일치시킨 후 볼트(9)로 고정시키면 간단히 양쪽 부품(1)(3)의 조립이 끝나게 되며 구형돌기(2)와 양측 분할편(5)(6) 사이에는 소착방지를 위하여 구형 분할베어링(12)을 개재시켜 체결하는 것이 보다 바람직하다.Hemispherical recesses (10) and (11) are formed in the two side pieces (5) and (6), respectively, for accommodating the spherical protrusions (2). (10) (11) are abutted on both sides of the spherical projection (2) of the piston (1) to align the flanges (7) (8) and then secured with bolts (9) to simply assemble both parts (1) (3). It is more preferable that the spherical protrusion 2 and the two side pieces (5) 6 are interposed between the spherical split bearing 12 to prevent seizure.
이에따라 피스톤과 커넥팅로드가 구형 결합되어 피스톤이 자유롭게 회전하게 된다.Accordingly, the piston and the connecting rod are spherically coupled so that the piston freely rotates.
이상과 같은 본 고안에 의하면 피스톤에 구형돌기를 일체로 형성하고 구형돌기를 수용하는 커넥팅 로드의 소단부를 분할편으로 형성하여 플랜지 체결하므로써 조립이 매우 간편하고 불순물이 유입될 위험성이 크게 줄어들어 부재의 마모가 방지되며 압축시 신기의 흐름에 따라 피스톤이 힘을 받는 방향으로 자연스럽게 회전하게 되어 와류형성을 촉진시켜 연소성능을 향상시키게 되는 효과가 있다.According to the present invention as described above, by assembling the flange by integrally forming the spherical protrusion on the piston and forming the small end portion of the connecting rod that accommodates the spherical protrusion as a divided piece, the assembly is very easy and the risk of introducing impurities is greatly reduced. Abrasion is prevented and the piston rotates naturally in the direction of the force according to the flow of the wearer, thereby promoting vortex formation and improving combustion performance.
