한편, 구동기어(3)에는 스패셜와셔(5)가 설치되며 구동기어(3)의 볼트공(3b)에 스페셜와셔(5)의 구멍(5a)를 맞추어 볼트(7)를 체결하여 고정하게 된다. 이를 위해, 스페셜와셔(5)의 원주방향을 따라 구동기어(3)의 볼트공(3b)에 대응하도록 다수의 구멍(5a)이 형성된다.On the other hand, a special washer (5) is installed in the drive gear (3), and the bolt (7) is fastened by fixing the holes (5a) of the special washer (5) in the bolt hole (3b) of the drive gear (3). . To this end, a plurality of holes 5a are formed to correspond to the bolt holes 3b of the drive gear 3 along the circumferential direction of the special washer 5.

그러나, 상술한 바와같이 구성된 오일펌프 구동기어(3)와 스페셜와셔(5)의 연결부는 엔진구동시 소음의 원인이 되는 것은 물론, 스페셜와셔 체결시 볼트(7)의 체결정도에 따라 구동기어(3)의 평면도가 유지되므로써 와셔체결시 정밀작업을 수행해야 하므로 구동기어 장착작업을 어렵게 하는 중대한 요인이 되고 있다.However, the connection portion between the oil pump driving gear 3 and the special washer 5 configured as described above may cause noise when driving the engine, as well as the driving gear according to the fastening degree of the bolt 7 when the special washer is fastened. As the flatness of 3) is maintained, precise work must be performed when the washer is fastened, which makes it difficult to install the driving gear.

따라서, 본 고안의 목적은 구동시 소음의 발생이 적고 체결작업이 용이한 크랭크 샤프트의 구동기어 장착구조를 제공하는 것이다.Accordingly, an object of the present invention is to provide a drive gear mounting structure of a crankshaft, which generates little noise during driving and which is easy to tighten.

도 1은 종래의 크랭크샤프트와 오일펌프 구동기어의 체결부의 분해사시도이다.1 is an exploded perspective view of a fastening portion of a conventional crankshaft and an oil pump driving gear.

도 2는 본 고안에 따른 크랭크샤프트와 오일펌프 구동기어 체결부의 분해사시도이다.2 is an exploded perspective view of the crankshaft and the oil pump driving gear coupling unit according to the present invention.

상술한 목적을 달성하기 위한 본 고안에 따른 크랭크 샤프트와 오일펌프 구동기어의 체결구조는 고정축의 선단면에 핀고정홈을 구비한 크랭크 샤프트; 고정축 삽입공의 양측으로 볼트공을 가진 핀삽입홈을 구비한 구동기어; 및 양단에 관통공을 구비한 핀으로 구성되어, 크랭크샤프트의 고정축에 구동기어를 삽입한 후 크랭크 샤프트의 핀고정홈과 구동기어의 핀삽입홈에 핀을 삽입하여 볼트로 고정하는 것을 특징으로 한다.Crank shaft and the oil pump drive gear according to the present invention for achieving the above object is a crank shaft having a pin fixing groove on the front end of the fixed shaft; A drive gear having a pin insertion groove having a bolt hole at both sides of the fixed shaft insertion hole; And pins having through holes at both ends, and inserting the drive gear into the fixed shaft of the crankshaft, and inserting the pin into the pin fixing groove of the crankshaft and the pin insertion groove of the drive gear to fix with bolts. do.

이하, 첨부 도면을 참조하여, 본 고안에 따른 크랭크 샤프트와 오일펌프 구동기어의 체결구조의 일 실시예에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, an embodiment of a fastening structure of the crank shaft and the oil pump drive gear according to the present invention will be described in detail.

도 2에 본 고안에 따른 크랭크 샤프트와 오일펌프 구동기어의 체결구조가 도시되어 있다. 도시된 바와 같이, 본 고안에 따른 크랭크 샤프트와 오일펌프 구동기어의 체결구조는 스페셜와셔를 사용하지 않고 구동기어(30)를 크랭크샤프트(21)에 직접체결하도록 구성된다.2 shows a fastening structure of the crankshaft and the oil pump driving gear according to the present invention. As shown, the fastening structure of the crankshaft and the oil pump drive gear according to the present invention is configured to fasten the drive gear 30 directly to the crankshaft 21 without using a special washer.

이를 위해, 본 고안에 따른 크랭크샤프트(21)의 선단에는 중앙에 핀고정홈(23)을 구비한 고정축(22)이 형성된다.To this end, a fixed shaft 22 having a pin fixing groove 23 in the center is formed at the front end of the crankshaft 21 according to the present invention.

또한, 오일펌프 구동기어(30)에는 크랭크 샤프트(21)의 고정축(22)에 고정될 삽입공(31)의 양측으로 핀(41)을 컴팩트하게 삽입하기 위한 핀삽입홈(32)이 형성되고, 핀삽입홈(32)의 양측에는 볼트(50)를 체결하기 위한 볼트공(33)이 형성된다.In addition, the oil pump driving gear 30 is formed with a pin insertion groove 32 for compactly inserting the pin 41 into both sides of the insertion hole 31 to be fixed to the fixed shaft 22 of the crankshaft 21. On both sides of the pin insertion groove 32, a bolt hole 33 for fastening the bolt 50 is formed.

한편, 본 고안에 따른 구동기어(30)의 핀삽입홈(32)에는 장방형이 사각패널 형태의 핀(40)이 삽입되며, 핀(40)은 양단에 볼트(50)가 관통할 관통공(41)이 형성된 것이다.On the other hand, the pin insertion groove 32 of the drive gear 30 according to the present invention is inserted into the rectangular pin 40 of the rectangular panel form, the pin 40 is a through hole through which the bolt 50 passes through ( 41) is formed.

이에따라, 본 고안에 따른 오일펌프 구동기어(30)는 크랭크 샤프트(21)의 고정축(22)에 체결되면 고정축(22) 선단의 핀고정홈(23)과 구동기어(30)의 핀삽입홈(32)이 일치하여 단일의 홈을 형성하게 되며, 여기에 핀(40)을 삽입하여 볼트(50)를 체결하므로써 조립이 이루어 진다.Accordingly, when the oil pump driving gear 30 according to the present invention is fastened to the fixed shaft 22 of the crank shaft 21, the pin fixing groove 23 and the pin insertion of the driving gear 30 at the tip of the fixed shaft 22 are inserted. The grooves 32 are matched to form a single groove, and the assembly is made by inserting the pin 40 therein to fasten the bolt 50.

상술한 바와 같이 구성된 본 고안에 따른 크랭크 샤프트와 오일펌프 구동기어의 체결구조를 사용하므로써, 구동기어는 크랭크 샤프트에 견고히 고정되며 별도의 와셔를 사용하지 않으므로 소음의 발생을 크게 저감할 수 있으며, 구조가 단순함은 물론 스페셜 와셔를 사용하지 않으므로 원가절감에도 기여할 수 있다.By using the fastening structure of the crankshaft and the oil pump drive gear according to the present invention configured as described above, the drive gear is firmly fixed to the crankshaft and does not use a separate washer can greatly reduce the generation of noise, structure The simplicity of course does not use special washers, which can contribute to cost savings.

또한, 구동기어가 크랭크 샤프트에 직접결합되어 한 쌍의 볼트만으로 결합이 이루어 지므로 평면도를 유지하기 위한 정밀한 작업이 요구되지 않으므로 조립작업성 향상에도 기여할 수 있다.In addition, since the driving gear is directly coupled to the crankshaft, the coupling is performed using only a pair of bolts, so precise work for maintaining the top view is not required, thereby contributing to the improvement of assembly workability.

이상에서 본 고안은 실시예를 통해 상세히 설명하였으나 본 고안은 이에 한정되는 것은 아니며 당해분야의 통상의 지식을 가진자라면 본 고안의 기술적 사상을 바탕으로 다양한 변형이나 수정이 가능할 것이며, 그러한 변경이나 수정은 다음의 청구범위에 포함되는 것이다.The present invention has been described in detail through the embodiments, but the present invention is not limited thereto, and one of ordinary skill in the art will be able to make various modifications or changes based on the technical idea of the present invention. Is included in the following claims.
