본 고안은 상부 안내부와 플랜지 시트 사이의 요홈에 밀폐링이 직접 억지끼워서맞춤되어 있는 내연기관상의 크랭크 케이스의 실린더 헤드 덮개에 플랜지 시트를 갖는 습식 실린더 라이너의 밀폐 시스템에 관한 것이다.The present invention relates to a closure system of a wet cylinder liner having a flange seat in a cylinder head cover of a crankcase on an internal combustion engine in which a sealing ring is directly interfitted with a recess between the upper guide and the flange seat.
실린더 헤드에 인접한 습식 실린더 라이너의 상부에 대한 이러한 밀폐배치는 오랫동안 본 기술분야에서 알려져 왔다. 이 배치에서, 실린더 리아너의 상부안내부는 밀폐링의 바로 아래에 오며, 양호안 안내를 제공하기 위해서 이 부분은 충분히 길어야함과 동시에 크랭크 케이스에 양호하게 접촉 되어야 한다. 다른한편, 이러한 접촉부위는 너무 길어서는 안된다. 왜냐하면, 이 부위가 너무 길면, 냉가수 공간이 하방으로 너무 멀리 변위되게 되어 가장 높은 응력을 받는 부분인 라이너의 상부에 대해 불충분한 냉각을 초래하게 되기 때문이다.Such closure arrangements for the top of a wet cylinder liner adjacent to a cylinder head have long been known in the art. In this arrangement, the upper guide of the cylinder liner is just below the sealing ring, and in order to provide good guidance, this part must be long enough and in good contact with the crankcase. On the other hand, these contacts should not be too long. This is because if this area is too long, the cold water space will be displaced too far downward, resulting in insufficient cooling to the top of the liner, the most stressed part.
비록 안내부가 양호하게 접촉되어 있다 할지라도 130℃ 내지 140℃정도의고온의 냉각수가 틈새를 통행 밀폐링에 침투하는 것을 피할수는 없다. 그런데, 배출 설비가 없기 때문에, 이 물은 그들 온도들에서 증발되어야 하고 그럼으로써 바람직스럽지 못한 염결정들이 생성되어, 결국에는 밀폐링을 부식 및 침식시켜 냉각수가 크랭크 케이스와 라이너 사이의 플랜지 시트에까지 도달하는 것을 허용하게 될 것이다. 따라서, 냉각수 누설을 발생하기가 쉬워지며, 이를 보수하기 위해서는 복잡하고 비용이 많이드는 수리를 요하게 된다.Although the guides are in good contact, high temperature cooling water, such as 130 ° C. to 140 ° C., cannot be penetrated through the gap into the passage sealing ring. However, since there is no drainage system, this water must evaporate at those temperatures and thus undesirable salt crystals are produced, eventually eroding and eroding the seal ring, which leads to the cooling water reaching the flange sheet between the crankcase and the liner. You will be allowed to. Therefore, it is easy to generate coolant leakage, and repairing it requires complicated and expensive repairs.
더구나, 냉각수가 플랜지 시트에 접근하게 되면, 이높은 응력을 받는 부위는 또한 시간이 경과함에 따라 부식 작용을 받게 되어 라이너 접촉면을 마멸시키므로써 라이너를 내려가게 할 것이며, 이 또한 일반적으로 크랭크 케이스의 재가공을 포함하는 복잡한 수리에 의해서만 개량될 수가 있다.Moreover, as the coolant approaches the flange seat, this highly stressed area will also corrode over time, causing the liner to descend by abrasion of the liner contact surface, which is also typically reworked of the crankcase. It can only be improved by complex repairs, including.
본 고안은 이러한점에 착안하여 이루어진 것으로서, 그 목적으로 하는 바는 라이너의 양호한 접촉 및 안내를 달성하기 위해서는 냉각수 공간을 더욱 하방으로 재배치할 필요없이 간단한 수단에 의해 냉각수 공간의 신뢰성있는 상부 밀폐를 제공하는데 있다.The present invention has been made with this in mind, and its purpose is to provide a reliable top seal of the coolant space by simple means without the need to rearrange the coolant space further down to achieve good contact and guidance of the liner. It is.
본 고안에 의하면, 이러한 목적은 라이너의 상부 안내부의 부위에 부가의 링홈을 제공하고, 이 홈에 제2 밀폐링을 설치하므로서 달성되었다.According to the present invention, this object has been achieved by providing an additional ring groove in the portion of the upper guide of the liner and installing a second sealing ring in the groove.
다른말로하면, 두개의 밀폐링이 나란히 제공되므로서. 상부 밀폐링은 냉각수와 접촉되는 일이 완전히 방지되고 안내부 자체는 소정갈이 이상은 냉각수에 노출되지 않고 유지되므로, 적극적인 염결정의 형성이 상당한 정도까지 배제된다. 이것은 적어도 2배정도의 수명연장을 보장해주며, 초기에 언급한 결점들을 완전히 제거해 준다.In other words, two sealing rings are provided side by side. The upper sealing ring is completely prevented from coming into contact with the cooling water and the guide portion itself is maintained without being exposed to the cooling water for a predetermined time or more, thereby preventing the formation of active salt crystals to a considerable extent. This guarantees at least twice the lifespan and completely eliminates the above mentioned shortcomings.
링홈의 폭은 그 깊이보다 크게 만드는 것이 바람직하며(그러나, 이것이 필요조건은 아니다), 따라서 실린더 라이너가 제위치에 압착될때 밀폐링은 약간의 휨 및 변형을 당하게 된다.It is desirable to make the width of the ring groove larger than its depth (but this is not a requirement), so the sealing ring is subject to some bending and deformation when the cylinder liner is pressed in place.
본 고안의 계속적인 전개에 따라. 제2밀폐링을 위한 링홈은 노치효과를 방지하기 위해 그 측부에 곡면부를 갖도록 형성된다는 것이 제안되어 있다.According to the continuous development of the present invention. It is proposed that the ring groove for the second sealing ring is formed to have a curved portion at its side to prevent the notch effect.
끝으로, 본 고안에 따라서, 라이너의 상부 안내부의 길이는 부가의 링홈에 의해 최대 40%까지 감소될수 있다는 것이 제안되었다. 이러한 특징은 라이너의 적절한 안내가 유지되는 것을 보장해주며, 냉각수 공간이 더욱 하방으로 재배치되어야 할 필요성을 배제해준다.Finally, according to the present invention it has been proposed that the length of the upper guide of the liner can be reduced by up to 40% by means of additional ring grooves. This feature ensures proper guidance of the liner is maintained and eliminates the need for the coolant space to be relocated further down.
이하, 첨부도면에 도시된 본 고안의 전형적인 실시예에 대한 설명으로부터 본 고안 보다 상세히 이해될 것이다.Hereinafter, the present invention will be understood in more detail from the description of exemplary embodiments of the present invention shown in the accompanying drawings.
도면은 크랭크케이스(2)내에 삽입되어 있는 실린더 라이너(1)의 일부단면도이다. 상기 라이너(1)은 크랭크케이스(2)의 실린더 헤드 덮개상에 플랜지 시트(4)를 갖고 있으며, 반경방향에서 크랭크케이스(2)내의 구멍을 안내부(3)에 접촉하게 해준다.The figure is a partial sectional view of the cylinder liner 1 inserted in the crankcase 2. The liner 1 has a flange seat 4 on the cylinder head cover of the crankcase 2 and allows the holes in the crankcase 2 to contact the guide 3 in the radial direction.
상부 안내부(3)와 플랜지 시트(4)사이의 요홈(5)에는 밀폐링(6)이 직접적으로 제위치에 끼워져 있다.In the groove 5 between the upper guide 3 and the flange seat 4, the sealing ring 6 is directly fitted into position.
냉각수 공간(7)에 제공된 냉각수로부터 이밀폐링(6)을 보호하기 위해서 부가의링홈(8)이 라이너(1)의 상부 안내부(3)의 부위에 형성되며, 이 홈에는 곡면부(9)가 형성되어 있고, 이 홈에도 또한 밀폐링(10)이 제위치에 끼워져 있다. 상기 링홈(8)의 초대폭은 적절한 안내를 보증하기 위해서 40%이상까지 안내부(3)의 길이가 감소되게 해서는 안된다. 예들들어, 만약 안내부(3)의 총 길이가 7.65㎜라고 한다면, 약4.65㎜의 최소 길이가 유지되어야만 한다.In order to protect the sealing ring 6 from the coolant provided in the coolant space 7, an additional ring groove 8 is formed in the part of the upper guide part 3 of the liner 1, in which the curved part 9 is provided. ) Is formed, and the sealing ring 10 is also fitted in this groove. The super wide width of the ring groove 8 should not allow the length of the guide 3 to be reduced by more than 40% to ensure proper guidance. For example, if the total length of the guide 3 is 7.65 mm, a minimum length of about 4.65 mm should be maintained.
