Description

오일여과용 필터가 삽입된 크랭크 샤프트Crankshaft with oil filter

본 고안은 피스톤의 직선운동을 회전력으로 전환하는 크랭크 샤프트에 관한 것으로 특히 기관으로 오일이 비산될 때 불순물이 걸러지도록 오일여과용 필터가 삽입된 크랭크 샤프트에 관한 것이다.The present invention relates to a crankshaft for converting a linear motion of a piston into a rotational force, and more particularly to a crankshaft in which an oil filtration filter is inserted to filter impurities when oil is scattered into an engine.

일반적으로 크랭크 샤프트는 크랭크 케이스 내에 설치된 메인 베어링으로 지지되며, 각 실린더에서의 팽창행정으로 얻어진 피스톤의 직선적 동력을 커넥팅 로드를 통해서 회전력을 바꾸고 또한 다른 행정에서는 반대로 피스톤에 운동을 줌으로써 연속적으로 동력을 발생하는 중요한 역할을 하는 것이다.In general, the crankshaft is supported by the main bearings installed in the crankcase, and the linear power of the piston obtained by the expansion stroke in each cylinder changes the rotational force through the connecting rod and generates power continuously by moving the piston in reverse on the other stroke. It plays an important role.

이러한 크랭크 샤프트의 내부에는 커넥팅로드, 베어링과 피스톤 핀으로 오일을 공급하기 위한 유로가 설치되며, 메인 베어링에 공급된 오일의 일부가 이 유로를 통해서 압송되도록 되어 있다.Inside the crankshaft, a flow path for supplying oil to the connecting rod, the bearing and the piston pin is installed, and a part of the oil supplied to the main bearing is pumped through the flow path.

그러나 종래의 경우 도 3 에서와 같이 엔진의 각 기관으로 압송되는 오일은 크랭크 샤프트(1)의 밸런싱 웨이트(2) 단부에 형성된 오일구멍(3)을 통하여 기관으로 오일이 비산되도록 하여 기관에서 발생되는 마모 및 냉각을 수행하도록 하였으나 기계적 마찰에 따른 불순물이 발생되더라도 오일필터에서 걸러지지 않은 불순물은 상기 크랭크 샤프트에 별도의 여과장치가 없기 때문에 실린더의 라이너에 직접 비산될 경우 라이너에 손상을 입혀 연소실의 압축력이 떨어지고 각종 기관까지 성능을 저하시켜 엔진의 출력이 감소되며 기관이 노후되는 문제점이 지적되고 있다.However, in the conventional case, oil pumped to each engine of the engine, as shown in FIG. 3, is generated in the engine by allowing the oil to splash into the engine through the oil hole 3 formed at the end of the balancing weight 2 of the crankshaft 1. Even though impurities caused by mechanical friction are caused by wear and cooling, impurities that are not filtered out of the oil filter are damaged by the liner when they are scattered directly to the liner of the cylinder because the crankshaft does not have a separate filtering device. This problem is pointed out that the engine output is reduced by deteriorating the performance of various engines and engines are old.

이에 본 고안은 상기한 문제점을 개선시키기 위하여 크랭크 샤프트에서 오일의 여과가 이루어지도록 하여 기관의 윤활 및 냉각이 이루어지게 하여 엔진의 출력이 증대되도록 하는데 본 고안의 목적이 있다.Therefore, the present invention has an object of the present invention to increase the output of the engine by lubrication and cooling of the engine is made by filtration of oil in the crankshaft to improve the above problems.

상기한 목적을 달성하기 위한 수단으로 본 고안은,The present invention as a means for achieving the above object,

오일구멍이 형성되어 회전운동시 오일이 비산되도록 형성된 크랭크 샤프트에 있어서,In the crankshaft formed oil hole is formed so that the oil is scattered during the rotational movement,

단부에 형성된 오일구멍의 상측으로 상부가 개방되어 삽입홈이 형성되도록 구성된 밸런스 웨이트와;A balance weight configured to have an upper portion open to an upper side of an oil hole formed at an end thereof so as to form an insertion groove;

상기 삽입홈으로 결합되며 불순물이 걸러지도록 결합되는 오일필터와 오일망;An oil filter and an oil net coupled to the insertion groove and coupled to filter impurities;

의 구성을 특징으로 한다.Characterized in the configuration.

이를 첨부한 실시예 도면을 참조하여 보다 상세하게 설명하면 도 1 은 본 고안에 의한 오일여과용 필터가 삽입된 크랭크 샤프트를 나타내는 단면도이고, 도 2 는 본 고안에 의한 필터와 오일망의 구조를 나타내는 사시도이다. 도면중 부호 1 은 크랭크 샤프트이고 부호 2 는 밸런스 웨이트이다.1 is a cross-sectional view illustrating a crank shaft into which an oil filtration filter according to the present invention is inserted, and FIG. 2 illustrates a structure of a filter and an oil net according to the present invention. Perspective view. In the figure, reference numeral 1 denotes a crankshaft, and reference numeral 2 denotes a balance weight.

크랭크 샤프트(1)에는 회전력이 증가되도록 밸런싱 웨이트(2)가 크랭크 핀 또는 크랭크 저널의 사이에 결합되어 있으며 내부로는 오일구멍(3)이 형성되어 오일이 기관으로 비산되도록 하였다. 상기한 밸런싱 웨이트(2)의 단부로는 오일구멍(3)이 형성되어 있으며 상측으로 상부가 개방된 삽입홈(4)이 구성되고, 상기 삽입홈(4)의 오일구멍(3) 입구에는 필터(6)가 끼워지고 상부로 오일망(5)이 결합되도록 구성되어 불순물(7)이 걸러지도록 하였다.In the crankshaft 1, a balancing weight 2 is coupled between the crank pins or the crank journal so that the rotational force is increased, and an oil hole 3 is formed therein to allow oil to splash into the engine. An oil hole 3 is formed at an end of the balancing weight 2, and an insertion groove 4 having an upper portion is opened upward. A filter is provided at an inlet of the oil hole 3 of the insertion groove 4. (6) is fitted and the oil net (5) is configured to be coupled to the top to filter the impurities (7).

상기와 같은 구성에 따른 작용을 살펴보면 우선 엔진에서 팽창행정시 피스톤의 직선운동에 의해 커넥팅 로드의 대단부와 체결된 크랭크 핀은 크랭크 샤프트(1)를 회전운동 시키게 되며 상기 크랭크 샤프트(1)의 밸런싱 웨이트(2)는 회전하면서 오일팬에 담겨진 오일을 기관으로 비산되도록 하게 되는 것이다.Looking at the action according to the configuration as described above, first, the crank pin coupled to the large end of the connecting rod by the linear movement of the piston during the expansion stroke in the engine to rotate the crank shaft (1) and the balancing of the crank shaft (1) The weight 2 rotates so that the oil contained in the oil pan is scattered to the engine.

상기의 오일이 기관으로 비산질 때 크랭크 샤프트(1)에 형성된 오일구멍(3)으로 오일의 일부가 공급되어지고 이러한 오일은 베어링, 크랭크 핀, 라이너로 비산되는 것이다.When the oil is scattered into the engine, a part of the oil is supplied to the oil hole 3 formed in the crankshaft 1, and the oil is scattered to the bearing, the crank pin and the liner.

그러나 상기한 오일팬의 오일은 엔진이 구동되면서 엔진의 각 부분으로 오일펌프에 의해 강제로 순환되고 있으나 기관에서 발생하는 각종 불순물(7)은 오일팬으로 다시 담기게 되어 오일필터의 여과없이 상기 크랭크 샤프트(1)에서 회전할 때 내부에 형성된 오일구멍(3)을 따라 밸런싱 웨이트(2)로 이동되는 것이다.However, the oil of the oil pan is forcibly circulated by the oil pump to each part of the engine while the engine is driven, but various impurities (7) generated in the engine are put back into the oil pan so that the crank is not filtered by the oil filter. When rotating on the shaft (1) is moved to the balancing weight (2) along the oil hole (3) formed therein.

상기와 같이 오일과 함께 유입된 불순물(7)이 밸런싱 웨이트(2)의 원심력으로 기관에 비산될 때 상기 오일구멍의 입구에 형성된 필터(6)에 의해 불순물(7)이 걸러지도록 하게 되며 상기 필터(6)에서 걸러지지 않고 통과되는 불순물(7)은 상기 필터(6)의 상측에 결합된 오일망(5)에서 다시한번 걸러지도록 하여 불순물(7)의 순환을 방지하게 되는 것이다.As described above, when the impurities 7 introduced together with the oil are scattered to the engine by the centrifugal force of the balancing weight 2, the impurities 7 are filtered by the filter 6 formed at the inlet of the oil hole. The impurity (7) passed through without filtering in (6) is once again filtered in the oil net (5) coupled to the upper side of the filter (6) to prevent the circulation of the impurities (7).

또한 상기의 오일망(5)은 촘촘한 구조로 형성되므로 필터(6)를 통과한 오일이 비산될 때 삽입홈의 상측이 개방되어 퍼질 수 있도록 하여 효과적인 냉각 및 윤활이 가능하게 되는 것이다.In addition, since the oil net 5 is formed in a dense structure, the upper side of the insertion groove can be opened and spread when the oil passing through the filter 6 is scattered, thereby enabling effective cooling and lubrication.

상기와 같은 본 고안에 의하면 오일필터에서 걸러지지 않은 불순물이 기관에서 순환되지 않도록 밸런스 웨이트에 필터와 오일망을 구성하므로서 불순물에 의한 기관의 마모가 감소되어 엔진의 성능이 향상되고 오일의 비산시 오일망의 촘촘한 구조에 의해 기관으로 분사되면서 공급되도록 하여 효과적인 냉각 및 윤활이 이루어져 엔진의 출력이 향상되는 유용한 고안인 것이다.According to the present invention as described above, by forming the filter and the oil net on the balance weight so that impurities not filtered out of the oil filter are not circulated in the engine, engine wear is reduced due to impurities, and engine performance is improved, and oil is scattered during It is a useful design to improve the engine output by effective cooling and lubrication is made by being supplied to the engine by the tight structure of the network.
