본 고안은 사격장의 이동표적에 사용되는 가동레일 휠로서 주로 단일 레일상에서 차축이 유동되도록 이루어진 가동레일 휠에 관한 것이다.The present invention is a movable rail wheel used for the moving target of the shooting range, and mainly relates to the movable rail wheel that the axle flows on a single rail.

기존 사격장의 이동표적에 사용되고 있는 제 3 도에 표시한 가동레일 휠은, 레일의 간격이 불일정한 경우 심한 충격소음과 이동표적의 차축이 탈선되는 등의 폐단이 있었다.The movable rail wheel shown in FIG. 3, which is used for the moving target of the existing shooting range, suffered severe impact noise and derailment of the moving target axle when the rail distance was irregular.

본 고안은 이와같은 사정에 비추어 이루어진 것으로써, 불일정한 레일에서도 차축일단 외주면과 레일 휠의 내주면에 스플라인을 형성하여, 차축이 유동되도록 한 것으로서, 상기, 충격소음과 탈선등을 방지함에 목적이 있는 것이다.The present invention has been made in view of the above circumstances, and the splines are formed on the outer circumferential surface of the axle and the inner circumferential surface of the rail wheel even in an uneven rail, so that the axle flows. will be.

이하 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter will be described based on the accompanying drawings.

본 고안은 차축(1)의 양단(1a)(1b)에 결합된 요부(5)를 형성한 레일 휠(2),(3)에 있어서, 차축의 일단(1a)에 마련된 홈(9)에 키이(7)를 내재시켜 나사(8)로 고정한 레일 휠(2)과, 차축의 다른 일단(1b)의 외주부에 스플라인(6)을 형성하여, 상기 레일 휠(3)의 내주면에 요설된 스플라인(6')과 상호결합하여 차축이 유동할 수 있도록 구성된 것이다.The present invention, in the rail wheel (2), (3) having the recessed portion (5) coupled to both ends (1a) (1b) of the axle (1), in the groove (9) provided at one end (1a) of the axle A spline 6 formed on the inner circumferential surface of the rail wheel 3 by forming a spline 6 on the outer circumference of the rail wheel 2 and the other end 1b of the axle with the key 7 embedded therein and fixed with a screw 8. In combination with (6 '), the axles are configured to flow.

먼저, 제 1 도는 본 고안의 레일 휠과 차축이 결합된 상태를 일부절결하여 나타낸 것으로서 차축의 양단(1a)(1b)에 각 레일 휠(2),(3)을 끼워 결합 시킬 수 있도록 이루어진 것이다.First, Figure 1 shows a state in which the rail wheel and the axle of the present invention is coupled to the cut part is made to couple each rail wheel (2), (3) to both ends (1a) (1b) of the axle. .

그리고 차축(1)의 일단(1a)에는 축길이 방향의 홈(9)을 형성하였고, 다음 일단(1b)의 외주부에는 스플라인(10)을 형성하였다.Then, one end 1a of the axle 1 was formed with a groove 9 in the axial length direction, and a spline 10 was formed at the outer periphery of the next one end 1b.

그리고 상기 차축의 일단(1a)에 형성된 홈(9)은, 레일 휠(2)을 키이(7)로서 차축에 결합하여 나사(8)로서 체결하여 고정시키는 것에 주목적이 있는 것이며, 이와 반대로 차축의 다른 일단(1b)은, 차축이 유동될 수 있도록 외주부에 스플라인(6)을 각설하여, 제 2 도에서와 같은, 레일 휠(3)의 내주면에 요설된 스풀라인(6')과 상호 결합할 수 있도록 하므로서, 불일정한 레일(4)에서 차축이 유동되어 간격을 유지하도록 한 것이다.The groove 9 formed in one end 1a of the axle is primarily intended for engaging the rail wheel 2 as the key 7 to the axle and fastening the screw as the screw 8. The other end 1b is provided with a spline 6 in the outer circumference so that the axle can flow, and is mutually engaged with the spool line 6 'concave on the inner circumferential surface of the rail wheel 3, as in FIG. By making it possible, the axle flows from the uneven rail 4 to maintain the spacing.

즉, 차축의 일단(1a)은 레일 휠(2)과 고정되어 차축의 일단(1a)이 유동되지 않도록 이루어진 것이고, 타단의 차축(1b)은 제 1 도에 표시한 화살표방향(축방향)으로 유동되도록 한것으로써, 이것을 제 2 도의 레일 휠 내주면에 형성된 스플라인을 나타내는 측면도에 표시한 바와같이, 레일 휠(3)의 내주면에 요설된 스플라인(6')과 차축(1b)이 계합되므로서 불균일한 레일에서 차축(1b)이 슬라이딩 되어 유동을 가져오게 한 것이다.That is, one end 1a of the axle is fixed to the rail wheel 2 so that one end 1a of the axle does not flow, and the axle 1b of the other end is in the arrow direction (axial direction) shown in FIG. By making it flow, the spline 6 'and the axle 1b concave on the inner circumferential surface of the rail wheel 3 engage with each other, as shown in the side view showing the spline formed on the inner surface of the rail wheel of FIG. The axle 1b is slid from the rail to bring about flow.

또한 상기 차축은 동력 전달축이나 부수축에 모두 적용가능한 것이다.In addition, the axle is applicable to both the power transmission shaft and the sub-axle.

그리고, 요부(5)를 형성한 레일 휠(2),(3)은 레일(4)과의 접촉되는 부분이 점접촉을 이루므로서, 레일의 재질은 특수강으로 제작 사용할 수도 있고, 본고안과 같은사격장의 이동표적에 있어서는 경양물이기 때문에 마모에 다른 내구성의 문제에는 하등 제약을 받지 않는 것이다.In the rail wheels 2 and 3 having the recessed portions 5, the parts in contact with the rails 4 are in point contact, so that the material of the rails may be made of special steel. Since it is a hard object in the moving target of the shooting range, it is not restricted to wear and other durability problems.

이와같이, 레일 휠의 요부(5)와 레일(4)이 접촉되지 않는 부분에 미소한 간극이 생기므로서 이물질 등의 영향을 받지 않도록 한것이며, 불균일한 레일에서도 축이 유동되므로 탈선과 충격소음을 방지하여 사격장의 이동표적에 효율적으로 사용할 수 있는 가동레일 훨인 것이다.In this way, a small gap is generated in the portion where the main portion 5 of the rail wheel and the rail 4 are not in contact with each other, so that it is not influenced by foreign matters. It is a movable rail that can be effectively used for moving targets of the shooting range.
