자동차용 캠샤프트와 캠기어의 조립장치Assembly device of automotive camshaft and cam gear

본 발명은 자동차용 캠샤프트와 캠기어의 조립장치에 관한 것으로, 더 상세하게는 조립성이 향상되고 캠샤프트의 절손을 방지할 수 있도록 발명된 것이다.The present invention relates to an assembling apparatus of a cam shaft and a cam gear for an automobile, and more particularly, to improve the assemblability and to prevent the cam shaft from being broken.

일반적으로 자동차의 엔진에는 캠샤프트와 캠기어가 장착된다.Generally, engines of automobiles are equipped with camshafts and cam gears.

이때, 캠샤트트는 캠의 작동위치를 감안하여 정확한 위치에 조립되는 것이 필수적이다.At this time, it is essential that the cam chart is assembled at the correct position in consideration of the operating position of the cam.

종래, 캠샤프트(10)와 캠기어(30)의 조립은 제 1도에서 도시한 바와 같이 캠샤프트(10)에 결합되는 핀이나 키이(2)로 캠기어(30)의 조립위치를 결정하게 된다.Conventionally, the assembly of the cam shaft 10 and the cam gear 30 is to determine the assembly position of the cam gear 30 with the pin or key 2 coupled to the cam shaft 10 as shown in FIG. do.

그리고, 아이들기어(3) 및 크랭크기어(5)와 타이밍마크(4)에 의해 그 치합위치를 결정하여 조립되도록 구성된다.Then, the engaging position is determined by the idle gear 3, the crank gear 5 and the timing mark 4 to be assembled.

이와같은 종래 자동차용 캠샤프트와 캠기어의 조립구조에 의하면, 타이밍 마크(4)의 표시에 의존하여 그 조립위치를 설정하여 작업해야 하므로 조립성이 저감된다.According to such a conventional assembling structure of a camshaft and a cam gear for automobiles, since the assembly position must be set in dependence on the display of the timing mark 4, assembling property is reduced.

또, 핀홀 및 키이(2)를 결합하기 위한 키이홈에 전단력이 발생되어 캠샤프트(10)가 취약해지거나 심하게는 절손되는 등의 폐단이 있었던 것이다.In addition, a shear force is generated in the key groove for coupling the pinhole and the key 2, so that the camshaft 10 becomes weak or severely broken.

도 1 은 종래 캠샤프트와 캠기어의 조립과정을 보인 장치도,1 is a device diagram showing an assembly process of a conventional cam shaft and a cam gear,

도 2 는 본 발명의 캠샤프트와 캠기어의 조립구조를 보인 일부절결 단면도,Figure 2 is a partially cutaway cross-sectional view showing the assembly structure of the cam shaft and the cam gear of the present invention,

도 3 은 도 1 의 A부에서 본 요부도.FIG. 3 is a main view of a portion A of FIG.

이러한 본 발명의 목적은, 캠샤프트(10)의 선단에 일자형의 조립돌기(11)를 형성하여 이 조립돌기(11)를 수용하도록 조립홈(21)이 파여지고, 헤드(1)에 조립되는 슬라이딩지그(20)에 고정시키고, 조립돌기(11)가 돌출되는 캠샤프트(10)의 타단은 테이퍼부(12)를 성형하여 캠기어(30)에 끼워 볼트(40)로 체결하는 것에 의해 달성된다.The object of the present invention is to form a linear assembling protrusion 11 at the tip of the cam shaft 10, the assembling groove 21 is dug to receive the assembly protrusion 11, and is assembled to the head (1) The other end of the camshaft 10 fixed to the sliding jig 20 and the assembly protrusion 11 protrudes is achieved by forming the taper portion 12 and fitting the cam gear 30 to the cam gear 30 to fasten the bolt 40. do.

상기한 본 발명에 의하면, 조립성이 향상된다.According to the present invention described above, the assembly properties are improved.

또, 핀이나 키이(2)를 설치하기 위한 키이홈에 전단력이 발생되어 캠샤프트가 절손되는 것을 미연에 방지하여 그 내구성과 제품의 신뢰도를 향상시키는 것이다.In addition, the shear force is generated in the key groove for installing the pin or key 2 to prevent the cam shaft from being broken, thereby improving its durability and reliability of the product.

이하, 첨부된 도면에 의거하여 본 발명의 바람직한 실시예를 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2 는 본 발명 장치의 실시예를 나타낸 것으로써, 흡배기밸브들을 개폐시키기 위한 캠(13)들이 복수로 배열되는 캠샤프트(10)의 일단에는 헤드(1)에 조립된 슬라이딩지그(20)에 결합하고, 그 타단은 캠기어(30)를 조립한 상태에서 볼트(40)로 체결한다.Figure 2 shows an embodiment of the present invention, one end of the cam shaft 10 is arranged a plurality of cams 13 for opening and closing the intake and exhaust valves on the sliding jig 20 assembled to the head (1) The other end thereof is fastened with the bolt 40 in the state where the cam gear 30 is assembled.

상기 슬라이딩지그(20)에는 캠샤프트(10)의 단부에 일자형으로 돌출되는 조립돌기(11)를 수용하는 조립홈(21)이 파여져 상호 결합되는 데, 이때 조립돌기(11)는 캠(13)의 돌출부와 일치되는 위치를 감안하여 성형하게 된다.The sliding jig 20 is provided with an assembly groove 21 for receiving an assembly protrusion 11 protruding in a straight line at the end of the cam shaft 10 is coupled to each other, wherein the assembly protrusion 11 is a cam 13 It is molded in consideration of the position corresponding to the protrusion of the.

따라서, 이 조립돌기(11)를 슬라이딩지그(20)의 조립홈(21)에 끼우는 과정으로 캠(13)의 위치를 결정하게 되는 것이다.Accordingly, the position of the cam 13 is determined by fitting the assembly protrusion 11 into the assembly groove 21 of the sliding jig 20.

한편, 상기 캠샤프트(10)의 타단에는 테이퍼부(12)가 성형되어 이와 상응하는 형상으로 보스(31)가 파여지는 캠기어(30)가 결합되어 그 외측에서 와셔(41)를 두고 볼트(40)가 체결된다.On the other hand, the other end of the cam shaft 10 is formed by the tapered portion 12 is coupled to the cam gear 30, the boss 31 is dug into the corresponding shape is coupled to the bolt (with a washer 41 from the outside) 40) is fastened.

그리고, 캠기어(30)와 아이들기어를 취부하여 볼트로 체결하게 되면, 타이밍이 자동 셋팅되는 것이다.When the cam gear 30 and the idle gear are mounted and fastened with bolts, the timing is automatically set.

이때, 캠기어(30)의 보스에는 테이퍼부(12)가 볼트(40)의 축력을 면압으로 받게 되므로 우수한 체결력을 갖게 되는 것이다.At this time, since the tapered portion 12 receives the axial force of the bolt 40 in the surface pressure, the boss of the cam gear 30 will have excellent fastening force.

이상에서 설명한 바와 같이 본 발명에 의하면, 조립성이 향상된다.As described above, according to the present invention, assemblability is improved.

또, 핀이나 키이(2)를 설치하기 위한 키이홈에 전단력이 발생되어 캠샤프트가 절손되는 것을 미연에 방지하여 그 내구성과 제품의 신뢰도를 향상시키는 등의 매우 유용한 발명인 것이다.In addition, it is a very useful invention to improve the durability and reliability of the product by preventing shearing of the camshaft due to the shear force generated in the key groove for installing the pin or the key (2).
