10 : 하우징 20 : 오일시일10 housing 20 oil seal
본 고안은 크랭크축(crank shaft)의 후단부 기밀유지구조에 관한 것으로서, 특히 시일을 하우징에 사출성형하여 일체로 제작하므로, 부품수가 줄어들도록 하고 생산비용이 저감되도록 하는 크랭크축 하우징의 시일구조에 관한 것이다.The present invention relates to the airtight holding structure of the rear end of the crank shaft, and particularly to the seal structure of the crankshaft housing which reduces the number of parts and reduces the production cost since the seal is injection molded into the housing. It is about.
일반적으로 자동차의 크랭크축은, 일단부에 플라이휠(fly wheel)이 취부되도록 하는 플랜지가 형성되고 타단부에 벨트(belt) 구동용 풀리(pulley)가 체결되도록 되어, 크랭크케이스(crank case)와 일체로 형성되는 실린더블록(cylinder block)의 하단부에 양단부의 회전이 가능하게 지지되고, 플라이휠이 취부되는 크랭크축의 일단부는 크랭크케이스와 플랜지 사이에 기밀용 크랭크축하우징이 정착되어 있다.In general, a crankshaft of an automobile has a flange for allowing a fly wheel to be mounted at one end thereof and a belt driving pulley at the other end thereof to be fastened, thereby integrally with the crank case. Both ends are rotatably supported at the lower end of the formed cylinder block, and an airtight crankshaft housing is fixed between the crankcase and the flange at one end of the crankshaft on which the flywheel is mounted.
여기에서, 크랭크축하우징은 제1도와 제2도에 도시되는 바와 같이, 알루미늄 다이케스팅에 의해 일정 직경의 내주면이 형성되고, 내주면 주변부에 체결구멍들이 형성되는 하우징(housing)(10)의 내주면에 고무재질의 오일시일(oil seal)(20)이 압입에 의해 착탈 가능하게 끼워져 있다.Here, the crankshaft housing has rubber on the inner circumferential surface of the housing 10 in which inner diameters of a predetermined diameter are formed by aluminum die casting, and fastening holes are formed around the inner circumference, as shown in FIGS. 1 and 2. An oil seal 20 made of material is detachably fitted by pressing.
이와 같이 구성되는 종래 크랭크하우징은, 크랭크축의 회전부 외주면에 오일시일(20)이 기밀하게 밀착되도록 하우징(10)이 삽입되고, 크랭크케이스에 하우징(10)이 체결구멍으로 삽입되는 볼트들에 의해 취부되어, 오일시일(20)에 의해 기밀유지가 이루어져 오일이 누출되는 것을 방지하도록 한다.In the conventional crank housing configured as described above, the housing 10 is inserted in such a way that the oil seal 20 is tightly adhered to the outer circumferential surface of the crankshaft, and the crankcase is mounted by bolts into which the housing 10 is inserted into the fastening hole. Thus, the oil seal 20 is made airtight so as to prevent the oil from leaking.
한편, 이러한 종래 크랭크축하우징은, 오일시일(20)이 지지될 수 있도록 하우징(10)의 내주면에 기계가공에 의한 요홈부를 형성하고, 고무와 스프링 등으로 제작된 오일시일(20)을 상기 요홈부에 압입시켜야 하기 때문에, 제작 및 조립공수가 많아지고, 조립시간이 길어지게 되어 생산비용이 상승되는 문제점이 있었다.On the other hand, such a conventional crankshaft housing, to form the groove portion by the machining on the inner peripheral surface of the housing 10 so that the oil seal 20 can be supported, the oil seal 20 made of rubber and spring, etc. Since it must be pressed into the grooves, the number of manufacturing and assembling work increases, the assembly time is long, there is a problem that the production cost increases.
본 고안의 목적은 상기와 같은 종래의 문제점을 해소하기 위해, 실린더블록과 크랭크축의 플랜지 사이에 장착되는 크랭크축하우징을 철판프래스에 의해 형성하고, 사출성형에 의해 오일시일을 하우징에 일체로 성형시켜, 제작 및 조립공수가 단축되도록 하는 크랭크축 하우징의 시일구조를 제공하는데 있다.An object of the present invention is to solve the conventional problems as described above, by forming a crankshaft housing mounted between the cylinder block and the flange of the crankshaft by the iron plate press, and integrally molding the oil seal to the housing by injection molding It is to provide a seal structure of the crankshaft housing to reduce the manufacturing and assembly labor.
이하 첨부된 도면에 의하여 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.
본 고안의 크랭크축도 일단부에 플라이휠이 취부되도록 하는 플랜지가 형성되고 타단부에 벨트 구동용 풀리가 체결되도록 되어, 크랭크케이스와 일체로 형성되는 실린더블록의 하단부에 양단부가 회전 가능하게 지지되고, 플라이휠이 취부되는 크랭크축의 후단부 플랜지와 크랭크케이스 사이에 기밀용 크랭크축하우징이 장착된다. 단, 본 고안은 제3도 내지 제5도에 도시되는 바와 같이, 일정 직경의 내주면이 형성되고 내주면 주변부에 체결구멍들이 형성되는 철판의 하우징(10)이 프레스에 의해 임의의 형상으로 절곡 제작되고, 하우징(10)의 내주면과 일측면에 오일시일(20)이 사출성형에 의해 일체로 형성됨을 그 기술적 구성상의 기본 특징으로 한다.The crankshaft of the present invention also has a flange for mounting the flywheel at one end and a belt driving pulley is fastened at the other end, so that both ends are rotatably supported at the lower end of the cylinder block formed integrally with the crankcase, and the flywheel An airtight crankshaft housing is mounted between the rear end flange of the mounted crankshaft and the crankcase. However, according to the present invention, as shown in FIGS. 3 to 5, the housing 10 of the iron plate having a predetermined diameter of the inner circumferential surface and fastening holes formed around the inner circumferential surface is bent into an arbitrary shape by a press. In addition, the oil seal 20 is integrally formed by injection molding on the inner circumferential surface and one side of the housing 10 as a basic feature of the technical configuration.
이와 같이 구성되는 본 고안은, 내주면과 일측면에 사출성형된 오일시일(20)이 접촉부에서 기밀작용을 하여 기관에서 오일이 누출되는 것을 방지하게 되며, 오일시일(20)이 하우징(10)에 일체로 구성되므로, 제작 및 조립시 별도의 요홈부를 형성하기 위한 가공공정이 삭제되고, 오일시일(20)을 압입하기 위한 조립공정이 없어지도록 한다.The present invention constituted as described above, the oil seal 20 injected into the inner circumferential surface and one side has an airtight action at the contact portion to prevent the oil from leaking from the engine, the oil seal 20 to the housing 10 Since it is configured integrally, the manufacturing process for forming a separate recess during manufacturing and assembly is eliminated, so that the assembly process for pressing the oil seal 20 is eliminated.
따라서, 이러한 본 고안은 제작 및 조립공수가 줄어들고, 조립시간이 단축되도록 하여, 전체적으로 생산비용이 저감되도록 하는 효과가 있다.Therefore, the present invention has the effect of reducing the manufacturing and assembly labor, the assembly time is shortened, the overall production cost is reduced.
이상에서 살펴본 바와 같이, 본 고안은 철판프레스에 의해 형성되는 하우징에 오일시일이 사출성형에 의해 일체로 성형되어, 제작 및 조립공수가 단축되도록 하는 매우 유용한 것이다.As described above, the present invention is very useful for the oil seal is integrally molded by injection molding in the housing formed by the iron plate press, thereby shortening the manufacturing and assembly labor.
