Description
본 발명은 두물체 사이에 삽입되어 기밀이 유지하는 오링에 관한 것으로서, 특히 링의 내부에 부피가 증대되는 수단이 삽입됨으로써 조립성과 밀폐 성능이 향상되도록 한 오링에 관한 것이다.The present invention relates to an O-ring inserted between two objects to maintain airtightness, and more particularly, to an O-ring for improving assembly and sealing performance by inserting a means for increasing volume inside the ring.
자동차의 엔진과 변속기 등에는 윤활유 및 작동유로 오일이 사용되는 바, 각 부품 사이로 오일이 누유되지 않도록 오링(O-Ring) 등의 기밀 유지 수단이 설치되어 있다.Since oil is used as lubricating oil and operating oil in engines and transmissions of automobiles, airtight means such as O-rings are provided to prevent oil from leaking between components.
즉, 엔진에는 실린더 헤드에 내재된 밸브 기구와 실린더 블록에 내재되는 크랭크 축, 피스톤, 커넥팅 로드 등에 윤활 및 냉각 작용을 할 수 있도록 엔진 오일을 사용하고 있고, 이와 같은 엔진 오일이 외부로 누유되지 않도록 축의 둘레에 오링이 설치되어 있다.In other words, the engine uses engine oil to lubricate and cool the valve mechanism in the cylinder head and the crankshaft, piston, and connecting rod in the cylinder block. O-rings are installed around the shaft.
또한, 수동 변속기나 자동 변속기에도 동력을 전달하기 위해 입력축 출력축, 각종 기어, 그리고 마찰 부재 등이 구비되어 있는 바, 여기서도 윤활작용과 냉각 작용을 할 수 있도록 변속기용 오일이 사용되고, 자동 변속기의 경우에는 각종 마찰 부재를 단속하기 위해 작동유로도 사용되고 있으므로 변속기 내에 사용되는 오일이 각 부품 사이에서 외부로 누유되지 않도록 오링이 설치되어 있다.In addition, an input shaft output shaft, various gears, and a friction member are provided to transmit power to a manual transmission or an automatic transmission. Here, transmission oil is used for lubrication and cooling, and in the case of an automatic transmission, Since it is also used as a working oil to interlock various friction members, an O-ring is installed so that oil used in the transmission does not leak out between the parts.
물론, 상기와 같은 엔진이나 변속기 이외에도 자동차에는 윤활유와 작동유가 사용되는 각종 부품들 사이에 오링이 사용된다.Of course, in addition to the engine or the transmission as described above, the O-ring is used between the various components in which the lubricating oil and the hydraulic oil are used.
도 1은 종래 기술의 오 링이 도시된 일부 절개 사시도이다.1 is a partially cut away perspective view showing a prior art o-ring.
종래 기술의 오 링(10)은 도 1에 도시된 바와 같이 환형으로 형성되고, 고무재 등 합성수지재로 된 단일 재질로 이루어진다.The o-ring 10 of the prior art is formed in an annular shape, as shown in Figure 1, made of a single material of a synthetic resin material such as rubber.
이와 같은 오링(10)은 두 개의 물체나 부품 사이에 설치됨으로써 두 물체 사이로 오일이 새는 것을 방지하게 된다.The O-ring 10 is installed between two objects or parts to prevent oil from leaking between the two objects.
여기서, 상기한 오 링(10)은 두 물체 사이에서 충분한 밀폐 기능을 갖기 위해서는 두 물체에 완전히 밀착되어 있어야 하므로 오링의 굵기는 커질수록 밀폐 성능은 좋아진다.Here, the o-ring 10 should be completely in close contact with the two objects in order to have a sufficient sealing function between the two objects, the greater the thickness of the O-ring, the better the sealing performance.
그러나, 상기한 바와 같이 두 물체 사이에서 밀폐 성능을 확실히 하기 위해 굵기를 크게 할 경우 두 개의 물체 사이에 조립할 때 쉽게 찢어지는 등 손상될 수 있고, 이로 인하여 밀폐 성능이 오히려 떨어지게 되고, 결국 각종 시스템의 작동이 원활하게 이루어지지 않거나 오일의 손실이 커지는 문제점이 발생하게 된다.However, as described above, if the thickness is increased in order to ensure the sealing performance between the two objects, it may be damaged, such as being easily torn when assembling between the two objects, resulting in a decrease in the sealing performance, and eventually The problem is that the operation is not performed smoothly or the loss of oil is large.
물론, 두 물체를 조립할 때 오링이 손상되지 않도록 조심해서 조립하면 되나 이는 부품의 조립성을 떨어뜨리는 결과를 초래하게 된다.Of course, when assembling the two objects may be carefully assembled so as not to damage the O-rings, but this will result in a lower assembly of the parts.
본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 오링의 내부에 내부로 스며든 오일에 의해 부피가 팽창되도록 하는 재질을 삽입하여 2중 구조로 구성함으로써 각종 부품의 조립성이 향상됨과 아울러 밀폐 성능도 향상되도록 하는 오링을 제공하는 데 있다.The present invention has been made in order to solve the above problems, by inserting a material to expand the volume by the oil soaked into the inside of the O-ring to configure a double structure to improve the assemblability of the various parts and seal It is to provide an O-ring that also improves performance.
상기한 과제를 실현하기 위한 본 발명의 오링은, 내부에 오일에 의해 부피가 증대되는 부피증대수단이 삽입되어 있고, 상기 부피증대수단은 상기 오링의 내부에 환형 구조로 삽입되어 있는 것을 특징으로 하여 가능하게 된다.O-ring of the present invention for realizing the above object is, the volume increasing means is inserted into the volume by the oil therein, the volume increasing means is characterized in that the inner ring is inserted in the annular structure It becomes possible.

이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
도 2는 본 발명에 따른 오링이 도시된 일부 절개 사시도이고, 도 3은 도 2의 A-A선 단면도이다.2 is a partial cutaway perspective view of the O-ring according to the present invention, Figure 3 is a cross-sectional view taken along line A-A of FIG.
본 발명의 오링(50)은 도 2에 도시된 바와 같이 외부링(51)과 내부링(55)의 2중 구조로 이루어져 두 물체 사이에 조립될 경우 오일에 의해 내부의 내부링(55)이 팽창되도록 이루어져 있다.O-ring 50 of the present invention consists of a double structure of the outer ring 51 and the inner ring 55, as shown in Figure 2 when the inner ring 55 is assembled by the oil when assembled between the two objects It is designed to expand.
즉, 상기 외부링(51)은 통상의 오링 재질인 합성 수지재 등으로 이루어지고, 내부링(55)은 오일이 내부에 스며들게 되면 부품음(Swelling) 현상에 의해 부피가 팽창되는 재질로 이루어져 있다.That is, the outer ring 51 is made of a synthetic resin material, such as a conventional O-ring material, and the inner ring 55 is made of a material that expands in volume by a swelling phenomenon when oil penetrates inside. .
여기서, 상기 외부링(51)은 합성수지재질로 이루어져 있으므로 두 물체 사이에 오일이 내재될 경우 내부로 미세한 양의 오일이 내부로 스며들게 된다. 하지만외부링(51)을 통해 오일이 쉽게 스며들지 않을 경우에는 미세 구멍을 형성하여 내부로 오일이 스며들게 할 수도 있을 것이다.Here, since the outer ring 51 is made of a synthetic resin material, when oil is embedded between two objects, a minute amount of oil penetrates into the inside. However, if the oil does not easily penetrate through the outer ring 51 may form a fine hole may allow the oil to penetrate the inside.
상기와 같이 이루어지는 본 발명의 오링은 두 물체 사이에 조립할 경우 내부로 스며든 오일에 의해 내부링(55)의 부피가 팽창하게 되므로 외부링(51)도 팽창되어 두 물체사이에 밀착되는 힘이 커지고, 이에 따라 기밀성도 높아지게 된다.O-ring of the present invention made as described above is the volume of the inner ring 55 is expanded by the oil soaked into the interior when assembled between the two objects, so that the outer ring 51 is also inflated and the force between the two objects increases This, in turn, increases confidentiality.
또한, 상기와 같은 오링(50)은 두 물체사이에 조립후 부피가 커지므로 굵기를 작게 하여도 오일에 의해 내부링(55)과 외부링(51)의 부피가 팽창하면서 충분한 밀폐 성능을 갖게되므로 두 물체 사이에 용이하게 조립할 수 있게 된다.In addition, the O-ring 50 as described above has a sufficient sealing performance as the volume of the inner ring 55 and the outer ring 51 is expanded by the oil even though the thickness is small since the volume increases after assembling between the two objects. It can be easily assembled between two objects.
따라서, 상기와 같이 구성되고 작용되는 본 발명의 오링은 두 물체 사이에 장착된 다음 내부로 스며든 오일에 의해 부피가 팽창하도록 구성되어 있기 때문에 밀폐 성능이 향상됨과 아울러 부품의 조립성도 향상되게 하는 이점을 제공하게 된다.Therefore, the O-ring of the present invention constructed and acted as described above is configured to expand in volume by oil penetrated into the inside after being mounted between two objects, thereby improving sealing performance and improving assembly performance of parts. Will be provided.
