본 고안은 각종 기계류의 전동구조에서 변속기어군을 형성함에 있어 2개의 각 단위기어를 매우 간단한 구조에 의하여 용이하게 체결시킬 수 있도록 한 스플라인축에서의 2기어 체결구조에 관한 것이다.The present invention relates to a two-gear fastening structure in a spline shaft that can be easily fastened by a very simple structure of two gears in the transmission gear group in the transmission structure of various machinery.

일반적으로 머시닝센터등과 같은 각종기계류 상품에 있어서는 대부분 변속장치(변속기어군)가 형성되는 바, 종래에는 각기 다른 크기의 기어(ㄱ)(ㄴ')를 제4도에 도시한 바와 같이 키이(ㄷ)와 와셔(ㄹ) 및 너트(ㅁ)를 이용하여 서로 체결하였던 관계로 많은 부품이 소요되었고 가공의 공정이 많았으며 또한 조립용 공구를 별도로 구비하여야 하는 폐단이 있었을 뿐만 아니라 그 과정이 번거러워 작업의 능률화를 기할 수 없었다.In general, a variety of machinery such as a machining center, such as a transmission gear (transmission gear group) is formed in most of the bar, conventionally different gear (a) (b ') of the different size as shown in Figure 4 ), Washer and nut (ㅁ) were fastened to each other, so many parts were required, and there was a lot of processing, and there was a closed end to be equipped with an assembly tool separately. Could not streamline.

따라서 본 고안은 전술한 바와 같은 종래의 제반결점에 착안하여 안출한 것으로서, 고안의 요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised in view of the above-mentioned general drawbacks, and the subject matter of the present invention will be described in detail by the accompanying drawings as follows.

제1도에 도시한 바와 같이, 기어(1)의 일측에 삽지간격부(2)가 형성되도록 삽지편(3)을 고착하되 그 상, 하부에는 삽지돌기(3')(3")를 돌설하였으며 중앙에는 다수의 계지홈(4')(4")이 형성된 스플라인축공(4)이 천설되었다.As shown in FIG. 1, the insertion piece 3 is fixed so that an insertion interval 2 is formed at one side of the gear 1, and the insertion protrusions 3 'and 3 "are protruded thereon. In the center, spline shaft hole 4 formed with a plurality of locking grooves 4 'and 4 "was laid.

한편, 기어(1)가 부착되는 타기어(5)의 일측면에는 삽지돌기(3')(3")가 돌설된 삽지편(3)과 동일형상의 감입홈(6)을 천설하였고 내주면에는 호형괘지턱(7)(7')과 괘지홈(8)(8')이 형성되었으며 중앙에도 기어의 축공과 동일형사의 스풀라인 축공(9)이 천설되었다.Meanwhile, one side of the gear 5 to which the gear 1 is attached is provided with a recess 6 having the same shape as the insertion piece 3 in which the insertion protrusions 3 'and 3 "are protruded. Arc-shaped ruled jaws (7) (7 ') and ruled grooves (8) (8') were formed, and a spool line shaft hole (9) of the same type as the shaft hole of the gear was laid in the center.

그리고 양기어(1)(5)의 축공(4)(9)에는 스플라인축(10)이 끼워진다.The spline shaft 10 is fitted into the shaft holes 4 and 9 of the two gears 1 and 5.

이와 같이 구성된 본 고안의 작용효과를 설명한다. 각종의 기계류상품에서 변속장치내의 변속기어군을 형성시키고자 각기 다른 크기의 기어(1)(5)를 서로 부착시키기 위해서는 먼저 기어(1)의 삽지편(3)을 기어(5)의 일측면에천설된 동일형상의 감입홈(6)내로 끼운뒤 기어(1)를 일측으로 회전시키면 삽지돌기(3')(3")는 기어(5)에 형성된 괘지홈(8)(8')내로 끼워지고 괘지턱(7)(7')은 간격부(2)내로 끼워져 제2도의 단면도시와 같은 상태로 견고하게 계합된다.It describes the effect of the present invention configured as described above. In order to form gear groups within the transmission in various machinery products, in order to attach gears 1 and 5 of different sizes to each other, first, the insertion piece 3 of the gear 1 is attached to one side of the gear 5. When the gear 1 is rotated to one side after inserting it into the recessed groove 6 of the same shape, the insertion protrusion 3 ', 3 "is inserted into the recessed groove 8, 8' formed in the gear 5. The raised jaw 7, 7 ′ is fitted into the gap 2 and is firmly engaged in the same state as in the cross-sectional view of FIG. 2.

이때 기어(1)(5)가 각기 회전작용되는 것을 방지하고 전동을 위해서 축공(4)(9)내로 스플라인측(10)을 끼우면 축공(4)(9)에 천설된 계지홈 내로 스플라인축(10)의 계지돌기가 감입되기 때문에 기어(1)(5)가 임의적으로 회동됨을 방지할 수 있고 항시 스플라인측(10)의 회전에 의하여 회동하게 되는 것이다.At this time, the gears (1) and (5) are prevented from rotating, respectively, and the spline side (10) is inserted into the shaft hole (4) and (9) for the transmission. Since the locking protrusion of 10) is prevented from being rotated arbitrarily, the gears 1 and 5 are always rotated by the rotation of the spline side 10.

그리고 통상의 방법과 같이 서로 일체화된 각기 다른 크기의 기어(1)(5)는 스플라인측(10)에서 슬라이딩 작용되면서 변속작용을 행하게 되는 것이다.And the gears (1) 5 of different sizes integrated with each other as in the conventional method is to perform the shifting action while sliding action on the spline side (10).

이상에서와 같이 본 고안은 매우 간단한 구조로 변속기어(1)(5)를 체결하여 일체화 시킬 수 있기 때문에 조립이 용이하고 많은 부품을 필요로 하지 않어 생산원가를 저렴하게 하고 종래와 같이 별도의 조립용공구를 구비할 필요가 없으며 또한 분해하기도 매우용이한작용효과가있다.As described above, the present invention can be integrated by fastening the transmission gears (1) and (5) in a very simple structure, which is easy to assemble and does not require many parts, which makes production costs cheap and separate assembly as in the prior art. There is no need to provide a tool and it is very easy to disassemble.
