[산업상 이용 분야][Industrial use]
본원 고안은 로커카바를 실린더헤드에 장착함에 있어서 누설을 방지하기 위해 삽입되는 고무가스켓(패킹)의 파손을 방지하는 로커카바의 장착구조 개선에 관한 것이다.The present invention relates to improving the mounting structure of the rocker cover to prevent the breakage of the rubber gasket (packing) is inserted to prevent leakage in mounting the rocker cover to the cylinder head.
[종래기술][Private Technology]
제3도에 도시하는 것과 같이 종래 로커카바(10)를 실린더헤드(11)에 장착하기 위해서는 양측 경계면상에 고무가스켓(12, 패킹)을 개재시켜 볼트(13)로 체결하고 있다.As shown in FIG. 3, in order to mount the conventional rocker cover 10 to the cylinder head 11, the bolt 13 is fastened via rubber gaskets 12 (packings) on both boundary surfaces.
[종래기술의 문제점][Problems with Prior Art]
종래의 경우 볼트(13)를 체결함에 있어서 오버토오크를 방지할 수 있는 수단이 없어 작업자의 감에만 의존하여 체결하고 있기 때문에 로커카바(10)의 하면이 실린더헤드(11) 상부면에 닿을 때까지 계속 조이게 되는 현상이 있게 된다. 그러나 고무의 성질상 어느정도 압축력이 가해질 경우 원래의 그 한계를 넘어서면 영구변형이 발생하여 복원력이 현저히 감소되므로써 밀봉력이 저하되어 유체의 누설을 가져오게 되는 문제점이 있게 된다.In the conventional case, since there is no means for preventing overtorque in fastening the bolt 13, the fastening depends only on the operator's sense, so that the bottom surface of the rocker cover 10 reaches the upper surface of the cylinder head 11. There is a phenomenon that keeps tightening. However, if the compressive force is applied to some extent due to the nature of the rubber, the permanent deformation occurs over the original limit and the restoring force is significantly reduced, resulting in a decrease in the sealing force, resulting in a leakage of the fluid.
[고안이 해결하고자 하는 과제][Problem to Solve]
이에 본원 고안은 상기한 문제점을 감안하여 안출한 것으로서 그의 목적으로 하는바는 고무가스켓의 파손을 방지하여 누설을 방지할 수 있는 로커카바의 장착구조를 제공하는데 있다.The present invention has been made in view of the above problems, and its object is to provide a mounting structure of a rocker cover that can prevent leakage of the rubber gasket to prevent leakage.
[과제를 해결하기 위한 수단][Means for solving the problem]
상기한 목적을 달성하기 위한 본원 고안의 수단은 실리더헤드와 로커카바 사이에 밀봉용 가스켓을 개재시켜 볼트 체결하는 구조에 있어서, 상기 로커카바의 실린더헤드 상면에 대항하는 하부면에는 상기 가스켓의 압축률을 고려한 높이를 가지고 복수개의 스토퍼가 돌출되어 있음을 특징으로 한다.Means of the present invention for achieving the above object is a structure for fastening the bolt through a sealing gasket between the cylinder head and the rocker cover, the lower surface opposed to the upper surface of the cylinder head of the rocker cover the compression rate of the gasket It has a height in consideration of the plurality of stoppers are characterized in that protruding.
[실시예]EXAMPLE
이하 본 고안의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
제1도는 본 고안에 의한 로커카바의 장착구조를 나타내는 요부 단면도이며, 제2도는 로커카바의 저면도이다.1 is a cross-sectional view of the main portion showing the mounting structure of the rocker cover according to the present invention, and FIG. 2 is a bottom view of the rocker cover.
도면중 부호1은 로커카바 본체이며 상기 본체(1) 하부에는 가스켓 장착홈(2)이 형성되며 고무등의 재질로 형성되는 가스켓(3)을 상기 홈(2)에 삽입한 후 실린더헤드(4) 상부에 볼트(5) 체결하여 장착한다.In the drawing, reference numeral 1 denotes a rocker cover body, and a gasket mounting groove 2 is formed below the main body 1, and a cylinder head 4 is inserted after inserting a gasket 3 formed of a rubber or the like into the groove 2. ) Fasten the bolt (5) to the upper part.
상기 로커카바(1)의 하부면(6)에는 상기 고무가스켓(3)의 압축률을 고려하여, 즉 볼트(5)체결에 의해 탄성력을 해치지 않으면서 밀봉력을 유지하게 되는 압축량()만큼의 높이를 갖는 복수개의 스토퍼(7)가 돌출되어 있다.The lower surface 6 of the rocker cover 1 takes into account the compression rate of the rubber gasket 3, that is, the amount of compression that maintains the sealing force without harming the elastic force by fastening the bolts 5 ( A plurality of stoppers 7 having a height equal to) protrude.
[효과][effect]
상기와 같은 본원 고안에 의하면 고무가스켓의 압축량을 고려한 높이의 스토퍼를 로커카바 하면에 돌출하도록 마련하므로써 볼트로 로커카바를 실린더헤드 상면에 체결하였을때 스토퍼에 의해 더이상 고무가스켓이 압축되는 것을 방지하게 되므로 가스켓 파손에 의한 오일의 누유를 방지하게 되는 효과가 있게 된다.According to the present invention as described above, the stopper having a height in consideration of the compression amount of the rubber gasket is provided to protrude on the lower surface of the rocker cover so that the rubber gasket is no longer compressed by the stopper when the rocker cover is fastened to the upper surface of the cylinder head with bolts. Therefore, there is an effect of preventing oil leakage due to gasket breakage.
