By forming a setting hole, the timing of the cam gear can be easily set, thereby improving workability.
일반적으로 디젤엔진 챠량의 캠구동은 캠기어를 이용하는 것으로, 이와같이 캠기어를 이용한 캠구동을 얻기 위한 캠샤프트에 캠기어의 체결구조는 도 1에 도시된 바와같이 캠샤프트(1)의 일단을 단차지게 형성하고, 이 단차진 부분에 캠기어(2)를 반달키(5')에 의해 결합하며, 상기 캠샤프트(1)의 일단 측부에서 와셔(3)와 볼트(4)로서 체결하는 것이다.In general, a cam drive of a diesel engine vehicle uses a cam gear. As shown in FIG. 1, a cam gear fastening structure of the cam shaft to obtain a cam drive using the cam gear is stepped on one end of the cam shaft 1. The cam gear 2 is coupled to the stepped portion by a vandal key 5 ', and is fastened as a washer 3 and a bolt 4 at one end of the cam shaft 1.
그러나, 이러한 구조는 캠샤프트(1)의 일단이 단차지게 형성되어 있음으로서 상기 단차진 부분의 내구성이 약하여 파손되고, 상기한 캠기어(2)를 결합하고 있는 볼트(4)가 풀리는 등의 이유로 불량이 발생되는 것이었다.However, such a structure is damaged because the end of the camshaft 1 is formed to be stepped and the durability of the stepped portion is weak, and the bolt 4 which couples the cam gear 2 is loosened. Defect was to occur.
또한, 상기한 캠샤프트(1)의 타이밍을 맞추기 위해서 캠기어(2)의 타이밍 마크를 맞추면 캠샤프트(1)는 자동으로 타이밍 세팅되도록 하기 위하여 캠기어(2)의 체결 부위에 반달키(5')를 사용함으로서, 구조가 복잡한 단점이 있었다.In addition, when the timing mark of the cam gear 2 is aligned in order to adjust the timing of the cam shaft 1, the cam shaft 1 is placed on the fastening portion of the cam gear 2 in order to automatically set the timing. By using '), the structure was complicated.
본 발명의 목적은 이와같은 문제점을 해결하기 위하여 발명된 것으로, 캠샤프트에 체결되는 캠기어의 취부면적을 증가시켜 내구성을 향상시키고, 캠샤프트와 캠기어의 타이밍을 쉽게 세팅할 수 있도록 하여 작업성을 향상시키도록 된 디젤엔진 차량의 캠샤프트와 캠기어의 체결구조를 제공함에 있다.An object of the present invention is to solve the above problems, to increase the mounting area of the cam gear is fastened to the cam shaft to improve the durability, and to easily set the timing of the cam shaft and cam gear workability To provide a fastening structure of the cam shaft and the cam gear of the diesel engine vehicle to improve the.

이하, 본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 발명에 따른 캠샤프트와 캠기어의 체결구조를 나타낸 단면도이고, 도 4는 본 발명에 따른 세팅용 지구를 나타낸 사시도로서, 디젤엔진 차량의 캠구동을 위한 캠샤프트(1)와 캠기어(2)의 체결구조에 있어서, 상기한 캠샤프트(1)와 캠기어(2)의 결합되는 부위에 각각 대응하는 테이퍼(1')(2')를 형성하여 와셔(3)와 볼트(4)로서 체결시킨 것이다.3 is a cross-sectional view showing the fastening structure of the cam shaft and the cam gear according to the present invention, Figure 4 is a perspective view showing the earth for setting according to the present invention, the cam shaft (1) and cam for driving the cam of the diesel engine vehicle In the fastening structure of the gear 2, the taper 1 'and 2' corresponding to the position where the cam shaft 1 and the cam gear 2 are coupled to each other are formed to form a washer 3 and a bolt ( 4) is fastened.
또한, 상기한 캠샤프트(1)의 일단면에는 타이밍 세팅용 홀(1a)을 형성하여 타이밍 세팅용 지그(5)를 이용하여 캠기어(2)와 캠샤프트(1)의 체결시 간단하게 타이밍을 세팅할 수 있도록 한 것이다.In addition, the timing setting hole 1a is formed in one end surface of the cam shaft 1, and the timing is easily performed when the cam gear 2 and the cam shaft 1 are fastened using the timing setting jig 5. It is to be able to set.
이와같이 구성된 본 발명은 캠샤프트(1)와 캠기어(2)의 결합부분이 테이퍼(1')(2')에 이해 결합됨으로서 체결 면적이 증가되어 내구성을 향상시킬 수 있는 것으로, 상기한 테이퍼(1')(2')에 의한 쐐기작용으로 결합됨으로서 동일한 회전이 이루어져 정확한 회전력을 전달할 수 있는 것이다.According to the present invention configured as described above, the coupling portion of the camshaft 1 and the cam gear 2 is coupled to the taper 1 'and 2' so that the fastening area can be increased to improve durability. 1 ') (2') is coupled by the wedge action by the same rotation is to be able to deliver the correct rotation force.
또한, 타이밍을 세팅하기 위해서는 타이밍 세팅용 지그(5)를 이용하여 상기한 타이밍 세팅용 홀(1a)에 끼우면 자동으로 세팅이 되는 것으로, 상기한 타이밍 세팅용 홀(1a)의 위치는 캠샤프트(1)의 1번 실린더가 상사점에 위치하였을 대 조립하도록 타이밍에 맞게 제작하는 것이다.In addition, in order to set the timing, the timing setting jig (5) is inserted into the timing setting hole (1a) by using the automatic setting. The position of the timing setting hole (1a) is a cam shaft ( When cylinder 1 of 1) is located at the top dead center, it is manufactured according to the timing.
이상의 설명에서 알 수 있듯이 본 발명의 디젤엔진 차량의 캠샤프트와 캠기어의 체결구조에 의하면, 타이밍 세팅된 상태에서 캠기어를 쉽게 조립할 수 있음으로서 작업성이 향상되고, 캠기어의 체결 면적을 증가시킴으로서 파손 및 볼트 풀림에 의한 불량을 방지할 수 있는 효과가 있다.As can be seen from the above description, according to the fastening structure of the cam shaft and the cam gear of the diesel engine vehicle of the present invention, it is possible to easily assemble the cam gear in the timing set state, thereby improving workability and increasing the fastening area of the cam gear. By doing so, there is an effect that can prevent failure due to breakage and bolt loosening.
