Description
본 고안은 크랭크축의 오일시일장치에 관한 것이다.The present invention relates to an oil seal device of the crankshaft.
크랭크축은 크랭크 케이스내에 설치된 메인베어링으로 지지되며 각 실린더의 팽창행정으로 얻어진 피스톤의 직선적 운동을 커넥팅로드를 통하여 회전력을 바꾸고 또한 다른 행정에서는 반대로 피스톤에 운동력을 전달해 주므로써 연속적으로 동력을 발생하는 엔진의 중요한 기구이다.The crankshaft is supported by the main bearings installed in the crankcase and changes the rotational force of the piston obtained by the expansion stroke of each cylinder through the connecting rod. It is an important organization.
크랭크축 내부에는 커넥팅로드, 베어링과 피스톤핀, 베어링으로 오일을 공급하기 위한 유로가 설치되며 메인베어링에 공급된 오일의 일부가 이 유로를 통해서 압송되도록 되어 있으며 크랭크실내의 오일이 바깥으로 누설되는 것을 차단하기 위하여 도 2 에서와 같이 오일시일부재(20)를 베어링(21)의 바깥측인 크랭크저널(22)과 리테이너(23) 사이에 개재시켜 설치하고 있다.Inside the crankshaft, a flow path for supplying oil to connecting rods, bearings, piston pins and bearings is installed, and some of the oil supplied to the main bearings is pumped through this flow path, and oil in the crankcase leaks outward. In order to block, as shown in FIG. 2, the oil seal member 20 is interposed between the crank journal 22 and the retainer 23 which are the outer side of the bearing 21. As shown in FIG.
그러나 상기한 오일시일부재(20)에 의하면 크랭크축이 회전하게 되므로 어느 정도 틈새가 형성되어지게 될 경우 그 틈새를 통하여 오일이 그대로 외부로 누출되어지게 되는 문제점이 있었다.However, according to the oil seal member 20, the crank shaft is rotated, so that if a gap is formed to some extent, there is a problem in that oil leaks to the outside through the gap.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 크랭크축 단부의 오일시일구조를 2중구조로 하여 내측시일부재를 통과한 오일은 다시 오일팬으로 회수되도록 하여 오일이 외부로 누설되는 것을 차단하는 크랭크축의 오일시일장치를 제공하는 데 있다.The present invention has been proposed in view of the above-mentioned problems, and its purpose is to double the oil seal structure of the crankshaft end so that the oil passing through the inner seal member is recovered to the oil pan to leak the oil to the outside. It is to provide an oil seal device of the crankshaft to block the operation.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 크랭크축의 오일시일장치를 나타내는 도면으로, 도면중 부호 1은 크랭크축이며, 부호 2는 크랭크저널이며, 부호 3은 크랭크축(1)을 지지하는 실린더블록이다.1 is a view showing an oil seal device for a crankshaft according to the present invention, wherein 1 is a crankshaft, 2 is a crank journal, and 3 is a cylinder block for supporting the crankshaft 1.
실린더블록(3)의 외벽에는 오일시일 리테이너(4)가 볼트(5) 장착, 또는 단일체로 형성되고 상기 리테이너(4)와 크랭크저널(2)과의 사이에 형성되는 공간에는 일정간격(공간, 6)을 두고 내측 오일시일부재(7)와 외측 오일시일부재(8)가 개재되어 있어 크랭크저널(2) 표면과의 틈새를 통하여 누설되는 오일을 1,2차로 차단하게 된다.An oil seal retainer 4 is formed on the outer wall of the cylinder block 3 by a bolt 5 or is formed in a single body, and a space is formed between the retainer 4 and the crank journal 2 at a predetermined interval (space, 6), the inner oil seal member 7 and the outer oil seal member 8 are interposed so that oil leaks through the gap between the surface of the crank journal 2 and the first and second blocks.
상기 양측 시일부재(7)(8) 사이에 형성되는 공간(6)에 연통하는 공기도입통로(9)가 상기 오일시일 리테이너(4)의 상부측으로 형성되어 있다.An air introduction passage 9 communicating with the space 6 formed between the seal members 7 and 8 on both sides is formed on the upper side of the oil seal retainer 4.
그리고 상기 리테이너(4)의 하부에는 상기 공기도입통로(9)와 공간(6)에 연통하는 오일회수통로(10)가 오일팬(11)을 연결하도록 형성되어 있다.And the lower portion of the retainer (4) is formed so that the oil return passage 10 in communication with the air introduction passage (9) and the space (6) to connect the oil pan (11).
이에따라 내측 오일시일부재(7)를 통과하여 공간(6)에 다다른 오일은 공기도입통로(9)를 통해 도입되는 공기에 의해 오일회수통로(10)를 통해 오일팬(11)내로 낙하 회수되는 것이다.Accordingly, the oil which passes through the inner oil seal member 7 and reaches the space 6 is dropped and recovered into the oil pan 11 through the oil return passage 10 by air introduced through the air introduction passage 9. will be.
이때 리테이너(4)의 크랭크저널(2)을 지지하는 하부측에는 오일의 수집을 위하여 요홈(12)을 형성하는 것이 더욱 바람직하며 외부로부터 도입되는 공기는 오일의 원활한 회수를 촉진하게 된다.At this time, it is more preferable to form the groove 12 for collecting oil on the lower side of the retainer 4 supporting the crank journal 2, and the air introduced from the outside facilitates the smooth recovery of the oil.
따라서 외측 오일시일부재(8)를 통과하여 외부로 배출되는 오일은 거의 없게 된다.Therefore, almost no oil is discharged to the outside through the outer oil seal member 8.
이상과 같은 본 고안에 의하면 크랭크축 단부에 설치되는 오일시일부재를 일정간격을 두고 내·외로 분리하여 설치하고 내측 오일시일부재를 통과한 오일은 오일팬으로 낙하회수되며 이때 외부로부터 공기가 유입되어 오일이 원활이 회수되어지도록 촉진하므로써 외부로 누출되는 오일량을 극소화하여 오일소모를 저감하게 되는 효과가 있다.According to the present invention as described above, the oil seal member installed at the end of the crankshaft is separated and installed inside and outside at a predetermined interval, and the oil passing through the inner oil seal member is recovered and dropped into the oil pan, and at this time air is introduced from the outside By promoting the smooth recovery of oil has an effect of minimizing the amount of oil leaking to the outside to reduce oil consumption.
