Abstract

PURPOSE: A main bearing lubricating apparatus for an engine is provided to prevent the bearing by permitting the oil to be directly supplied to the main bearing from the oil pan. CONSTITUTION: A crank shaft(20) is supported by a main bearing(30) within a crank case, and an oil pan(14) is attached to the bottom of the crank case. The main bearing has an oil inlet pipe(40) inserted into the main bearing in such a manner that the oil inlet pipe is directed toward the oil pan. A shaft(42) connected to the crank shaft through a belt(41) has an oil supply spoon(43) mounted to the shaft at a constant spacing in such a manner that the oil supply spoon rotates along with the rotation of the crank shaft, and the oil is splashed into the oil inlet pipe through the rotation of the oil supply spoon. Since the oil is directly supplied to the main bearing, the oil is prevented from being mixed with dust or chips.

Description

엔진의 메인베어링 윤활장치Main Bearing Lubricator of Engine

본 발명은 엔진의 메인베어링 윤활장치에 관한 것으로, 더 상세하게는 오일팬내의 오일을 직접 메인베어링으로 공급하여 더스트나 칩의 유입을 방지하는 것에 의해 메탈의 소착을 미연에 방지할 수 있도록 발명된 것이다.The present invention relates to a main bearing lubricator of an engine, and more particularly, to prevent the seizure of metal in advance by supplying the oil in the oil pan directly to the main bearing to prevent the inflow of dust or chips. will be.

일반적으로 엔진의 윤활은 엔진 내부의 마찰저항을 저감함과 동시에 엔진 내부의 냉각의 기능을 가지고 있다.In general, the lubrication of the engine has a function of cooling the engine while reducing frictional resistance inside the engine.

엔진에는 이 윤활을 위한 엔진 오일이 주입되어 있다.The engine is infused with engine oil for this lubrication.

엔진의 윤활방식에는 오일 펌프에 의한 압송과 주요운동부분의 비산(spresh)에 의한 것이 있다.The lubrication of the engine involves oil pumping and splashing of the main moving parts.

또, 일반적으로는 엔진 오일을 엔진 하부의 오일팬(14)에 모아 이것을 오일펌프(11)로 주요부분에 보내는 습식 섬프방식이 사용되고 있다.In general, a wet sump method is used in which engine oil is collected in an oil pan 14 at the lower part of the engine, and the engine oil is sent to a main part by an oil pump 11.

엔진 내부의 윤활은 주요운동부분은 물론, 밸브 장치에서 실린더까지 모든 것에 대해서 윤활하고 있다.Lubrication inside the engine lubricates everything from the valve mechanism to the cylinder, as well as the main moving parts.

주요운동부분의 크랭크 축(20), 커넥팅로드, 피스톤에 대한 윤활의 마찰저항은 물론, 고온이 되는 피스톤과 실린더의 냉각이 큰 비중을 점하고 있다.The frictional resistance of lubrication for the crankshaft 20, the connecting rod, and the piston of the main movement part, as well as the cooling of the piston and the cylinder, which becomes a high temperature, has a large proportion.

또, 피스톤과 실린더의 기밀성도 엔진 오일에 의해서 유지되고 있으며, 크랭크 축을 지지하는 메인베어링(30)에 대한 윤활은 오일펌프(11)에 의한 압송으로 이루어 진다.In addition, the airtightness of the piston and the cylinder is also maintained by the engine oil, and lubrication of the main bearing 30 supporting the crankshaft is performed by the pressure pump by the oil pump 11.

엔진의 가장 아래에 있는 엔진 오일의 받침접시용으로 오일팬(14)이 위치된다.The oil pan 14 is positioned for the base plate of the engine oil at the bottom of the engine.

오일팬(14)의 일부는 다른 부분 보다 더욱 깊게 패여져 있으며 이 부분에 엔진오일을 저장하였다가 오일 펌프(11)에서 끌어올리도록 되어 있다.A portion of the oil pan 14 is deeper than the other portion and is configured to store engine oil in this portion and to lift it from the oil pump 11.

종래, 오일팬(14)의 오일이 오일펌프(11)와 오일필터(12)를 거쳐 다시 실린더 블록의 오일갤러리(13)들을 거치기 때문에 크랭크축(20)을 지지하는 메인베어링(30) 까지 오는 동안 블록의 가공 칩(CHIP)이나 기타 다른 부품들의 더스트를 포함하고 있다.Conventionally, since the oil of the oil pan 14 passes through the oil galleries 13 of the cylinder block through the oil pump 11 and the oil filter 12, the oil comes to the main bearing 30 supporting the crankshaft 20. While it contains dust from the machined chip (CHIP) or other parts of the block.

이와같이 여러 통로를 거쳐 메인베어링(30)으로 오일이 공급되는 경우 오일에 포함된 칩이나 먼지등과 같은 이물질이 윤활부로 침입하여 메탈의 소착가능성을 높일 뿐만 아니라, 윤활성능의 저하로 엔진 출력이 저하되는 등의 폐단이 있었던 것이다.In this way, when oil is supplied to the main bearing 30 through several passages, foreign matters such as chips or dust contained in the oil enter the lubrication part to increase the adhesion of the metal to the lubrication part, and the engine output is reduced due to the deterioration of lubrication performance. There was an end to such being.

본 발명의 목적은 오일을 직접 메인베어링으로 공급하여 더스트나 칩의 유입을 차단하여 메탈의 소착을 미연에 방지할 수 있도록 한 엔진의 메인베어링 윤활장치를 제공하는 데 있다.It is an object of the present invention to provide a main bearing lubrication apparatus for an engine that can directly supply oil to a main bearing to block dust or chip inflow, thereby preventing metal deposits in advance.

본 발명의 다른 목적은 엔진의 성능과 내구성을 향상시킬 수 있도록 한 엔진의 메인베어링 윤활장치를 제공하는 데 있다.Another object of the present invention is to provide a main bearing lubricator for an engine to improve the performance and durability of the engine.

이러한 본 발명의 목적은, 엔진의 크랭크 케이스(10) 내에 메인베어링(30)으로 크랭크축(20)을 지지하고, 하측에 오일이 채워지는 오일팬(14)이 부착되는 것에 있어서;The object of the present invention is to support the crankshaft 20 with the main bearing 30 in the crankcase 10 of the engine, and to attach an oil pan 14 filled with oil on the lower side thereof;

상기 메인베어링(30)에 오일팬(14)을 향해 오일유입관(40)을 끼우고, 상기 오일팬(14)에 크랭크축(20)으로 부터 벨트(41)로 연결되어 함께 회동되는 샤프트(42)에 일정간격 오일공급용 주걱(43)을 설치하여 이 오일공급용 주걱(43)의 회동으로 오일이 오일유입관(40)으로 비산되도록 구성하는 것에 의해 달성된다.The oil inlet pipe 40 is inserted into the main bearing 30 toward the oil pan 14, and the shaft is connected to the oil pan 14 by a belt 41 from the crankshaft 20 and rotated together ( It is achieved by providing a spacing 43 for oil supply spacing 43 at a predetermined interval so that the oil is scattered to the oil inflow pipe 40 by the rotation of the oil supply spatula 43.

따라서, 메인베어링(30)의 하측에서 직접 오일이 윤활부로 공급되므로 먼지나 칩과 같은 이물질에 의해 메탈이 소착되는 것을 미연에 방지할 수가 있다.Therefore, since the oil is directly supplied to the lubrication portion from the lower side of the main bearing 30, it is possible to prevent the metal from sintering by foreign matter such as dust or chips.

또, 엔진의 출력과 내구성을 향상시킬 수 있는 것이다.In addition, the engine output and durability can be improved.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의해 상세하 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3는 본 발명의 장치를 보인 측단면도로 메인베어링(30)에 오일유입관(40)을 설치하여 이 오일유입관(40)을 향해 오일팬(14) 내에서 회동하는 오일공급용 주걱(43)에 의해 오일이 직접 전달되는 상태를 도시하고 있다.3 is a side cross-sectional view showing the apparatus of the present invention by installing the oil inlet pipe 40 in the main bearing 30, the oil supply spatula rotating in the oil pan 14 toward the oil inlet pipe 40 ( 43 shows a state in which oil is directly delivered.

상기 메인베어링(30)은 엔진의 크랭크 케이스(10) 내에 크랭크축(20)을 회전 자유롭게 지지하게 되며, 크랭크 케이스(10)의 하측에는 오일이 채워지는 오일팬(14)이 부착된다.The main bearing 30 rotatably supports the crankshaft 20 in the crankcase 10 of the engine, and an oil pan 14 filled with oil is attached to the lower side of the crankcase 10.

이 오일팬(14)의 일측에는 오일을 갤러리홀로 공급하기 위한 스트레이너(15)가 설치된다.One side of the oil pan 14 is provided with a strainer 15 for supplying oil to the gallery hole.

한편, 상기 메인베어링(30)에는 오일팬(14)을 향해 오일유입관(40)을 수직하게 끼워 오일팬(14)과 크랭크축(20)의 윤활부가 연통되도록 한다.Meanwhile, the oil inlet pipe 40 is vertically inserted into the main bearing 30 so that the lubrication portion of the oil pan 14 and the crankshaft 20 communicate with each other.

그리고, 상기 오일팬(14)내에는 엔진의 폭발에 의해 회전되는 크랭크축(20)의 동력을 이용하기 위해 벨트(41)로 연결되는 샤프트(42)가 크랭크축(20)과 나란하게 하측에 설치된다.In addition, in the oil pan 14, a shaft 42 connected to the belt 41 in order to use the power of the crankshaft 20 rotated by the explosion of the engine is parallel to the crankshaft 20. Is installed.

이 샤프트(42)에는 일정간격 오일공급용 주걱(43)을 설치하게 되는 데, 이 오일공급용 주걱(43)은 오일유입관(40)과 대응되는 위치에 각각 메인베어링(30)의 하측에서 회동되는 것이다.The shaft 42 is provided with an oil supply spatula 43 at a predetermined interval, and the oil supply spatula 43 is located at the lower side of the main bearing 30 at a position corresponding to the oil inlet pipe 40, respectively. It is rotated.

따라서, 상기 크랭크축(20)과 벨트(41)에 의해 크로스상태로 연결되어 함께 회동되는 샤프트(42)가 오일공급용 주걱(43)과 함께 회전될 때 오일팬(14) 내의 오일이 도 3에서와 같이 오일공급용 주걱(43)에 담겨진 상태로 오일유입관(40)내로 비산되는 것에 의해 메인베어링(30)으로 오일이 여러 통로를 거치지 않고 직접 전달될 수 있는 것이다.Accordingly, when the shaft 42 connected in the cross state by the crankshaft 20 and the belt 41 and rotated together with the oil supply spatula 43 is rotated, the oil in the oil pan 14 is shown in FIG. 3. By being scattered into the oil inlet pipe 40 in the state to be contained in the oil supply spatula 43 as in that the oil can be delivered directly to the main bearing 30 without passing through several passages.

상기와 같은 본 발명은, 메인베어링(30)의 하측에서 직접 오일이 윤활부로 공급되므로 먼지나 칩과 같은 이물질에 의해 메탈이 소착되는 것을 미연에 방지할 수가 있다.In the present invention as described above, since the oil is directly supplied to the lubrication portion from the lower side of the main bearing 30, it is possible to prevent the metal from being sintered by foreign matter such as dust or chips.

또, 엔진의 출력과 내구성을 향상시킬 수 있는 등의 매우 유용한 발명인 것이다.In addition, it is a very useful invention such as to improve the output and durability of the engine.
