Description
본 발명은 엔진의 크랭축에 결합되어 커넥팅 로드에서 받는 큰 하중이나 충격을 흡수하며 윤활작용을 하는 크랭크 축 베어링의 구조에 관한 것이다.The present invention relates to a structure of a crankshaft bearing which is coupled to a crankshaft of an engine and absorbs a large load or impact received from a connecting rod and lubricates.
일반적으로 크랭크 축에 사용되는 베어링은 그 표면에 적당한 유막을 형성하여 연소실에서 발생하는 폭발압을 흡수하며, 크랭크 샤프트의 회전으로 생기는 고체 마찰을 액체 마찰로 바꾸어 눌어 붙는 것을 방지할 뿐만아니라 접촉면의 마모나 출력의 손실을 적게하는 역할을 하고 있다.In general, the bearings used for the crankshaft absorb the explosive pressure generated in the combustion chamber by forming an appropriate oil film on the surface, and not only prevent the crushing of the solid friction caused by the rotation of the crankshaft with liquid friction but also wear on the contact surface. I play a role in reducing the loss of output.
그러나 종래 발명인 도 3 에 의하면 상기 폭발행정시 받는 압력에 별도의 장치가 없으므로 커넥팅 로드의 대단부와 베어링의 자체 마모가 심하고 또한 크랭크 축이 회전함에 따라 폭발압 및 마찰력에서 발생하는 이물질을 여과없이 오일 공급 통로를 통하는 윤활작용을 반복하므로 기계적 마모가 심하여 엔진 출력의 저해 요인이 되는 문제점이 있었다.However, according to FIG. 3 of the related art, since there is no separate device in the pressure received during the explosive stroke, wear of the large end of the connecting rod and the bearing itself is severe, and as the crank shaft rotates, foreign substances generated from the explosive pressure and friction force are filtered without oil. Since the lubrication through the supply passage is repeated, there is a problem that the mechanical wear is severe and the engine output is a detrimental factor.
이에 본 발명은 상기한 문제점을 개선시키기 위하여 폭발압에 대한 충격과 이물질의 흐름을 방지하는데 그 목적이 있다.Accordingly, the present invention has an object to prevent the impact of the explosion pressure and the flow of foreign matter in order to improve the above problems.
본 발명은 상기와 같은 목적을 달성하기 위한 수단으로서, 크랭크 축을 감싸는 베어링의 구조에 있어서, 상기 베어링의 중앙부에 설치되어 이물질의 흐름을 방지하는 여과용 필터,와 상기 여과용 필터의 양측에 대칭으로 ⊂ 형상이 조립된 상부 케이스,와상기 상부케이스의 내측에 삽입되어 폭발압을 흡수하는 탄성부재,와 상기 탄성부재의 하부에서 형상이 대칭으로 위치하며 상부케이스와 결합되도록 구성된 하부 케이스,와의 구성을 특징으로 한다.The present invention as a means for achieving the above object, in the structure of the bearing surrounding the crankshaft, is installed in the central portion of the bearing filter for preventing the flow of foreign matter, and symmetrically on both sides of the filter for filtration 상부 a configuration with an upper case assembled with a shape, and an elastic member inserted into the upper case to absorb the explosion pressure, and a lower case configured to be symmetrically positioned at the lower portion of the elastic member and coupled to the upper case. It features.

이를 첨부한 실시예 도면을 참조하여 보다 상세하게 설명하면, 도 1 은 본 발명의 사시도 도 2 는 도 1 의 A - A 선 단면도이다. 부호 1 은 상부 케이스이고 부호 2 는 하부 케이스이다.Referring to this in more detail with reference to the accompanying drawings, Figure 1 is a perspective view of the present invention Figure 2 is a cross-sectional view taken along line A-A of FIG. 1 is the upper case and 2 is the lower case.
크랭크축을 감싸며 접촉하는 상부 케이스(1)는 ⊂ 자 형상이 대칭으로 구성되고 상기 상부 케이스(1)의 내측으로는 폭발행정시 받는 강한 충격을 흡수하기 위하여 탄성부재(3)를 삽입하였으며, 상기 탄성부재(3)의 하부와 상부 케이스(1)의 상측 사이에는 하부 케이스(2)를 결합하도록 하고, 상기 하부 케이스(2)의 하부로는 오일이 유동될 수 있도록 형성하였다.The upper case 1, which wraps and contacts the crankshaft, has a U-shape in symmetrical shape, and an elastic member 3 is inserted into the upper case 1 to absorb the strong impact received during an explosion stroke. The lower case 2 is coupled between the lower part of the member 3 and the upper side of the upper case 1, and the lower case 2 is formed to allow oil to flow.
또한 하부케이스(2)의 중앙부에는 유동되는 오일이 크랭크 축에 유막을 형성할 수 있도록 오일 공급 통로(5)가 구비되며 상기 오일 공급 통로(5)의 상측으로는 이물질의 흐름을 막도록 여과용 필터(4)를 구비하여 결합하였다.In addition, the central portion of the lower case (2) is provided with an oil supply passage (5) so that the flowing oil to form an oil film on the crank shaft, and the upper side of the oil supply passage (5) for filtering to prevent the flow of foreign matter The filter 4 was provided and combined.
이상과 같이 구성된 본 발명은 연소실에서 발생하는 폭발압을 커넥팅 로드에 연결된 크랭크 축으로 전달되고, 크랭크 축을 감싸는 베어링의 상부 케이스(1) 내측에 삽입된 탄성부재(3)가 폭발에 따른 강한 충격을 흡수하도록 하는 것이다.According to the present invention configured as described above, the explosion pressure generated in the combustion chamber is transmitted to the crank shaft connected to the connecting rod, and the elastic member 3 inserted inside the upper case 1 of the bearing surrounding the crank shaft has a strong impact due to the explosion. To absorb it.
또한 크랭크 축과 커넥팅 로드의 대단부는 충격 및 회전운동에 따른 기계적 마모에 의해 이물질이 발생하게 되며 상기 이물질은 오일과 함께 오일 공급 통로(5)로 유입되나 하부 케이스(2)의 중앙부에 설치된 여과용 필터(4)에 의해 걸러지면서 크랭크 축을 향하여 분사되도록 하는 것이다.In addition, a large part of the crankshaft and the connecting rod generates foreign matters due to mechanical wear due to impact and rotational movement. The foreign matters flow into the oil supply passage 5 together with the oil, but are installed in the center of the lower case 2. It is to be injected toward the crank axis while being filtered by the filter (4).
상기와 같이 구성된 본 발명은 크랭크 축에서 발생하는 폭발압에 대한 흡수성을 가지며, 엔진의 가동에 의해 발생하는 각종 이물질에 대해 여과용 필터에 의하여 걸러지므로 기계의 수명이 연장될 뿐만 아니라 엔진의 성능 향상에도 유용한 발명인 것이다.The present invention configured as described above has an absorbency against the explosion pressure generated in the crankshaft, and is filtered by the filter for filtering various foreign matters generated by the operation of the engine not only extends the life of the machine but also improves the performance of the engine. It is also useful invention.
