본 발명은 횡류수차용 러너의 제작방법에 관한 것으로, 더욱 상세하게는 러너의 제작시 접합작업만을 통하여 러너를 완성시킴으로써 원가절감 및 작업생산성을 높일 수 있는 고성능 횡류수차용 러너의 제작방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a transverse aural drive runner, and more particularly, to a method for manufacturing a high-performance transverse aural drive runner capable of reducing cost and improving work productivity by completing a runner only through a joining operation .

일반적으로 수력발전은 육상에 존재하는 물의 유량과 낙차를 이용한 위치에너지를 기계에너지로 변환시켜 발전하는 것이다. 이러한 수력발전을 위한 수력기계는 물이 많은 장소에 댐이나 저수조를 설치하여 상기 물을 유입함은 물론 유입된 물의 유량과 낙차를 이용하여 터빈을 회전시켜 동력 및 전기가 발생되도록 장치를 구성한 것이다.Generally, hydroelectric power is generated by converting the position energy using mechanical energy and the flow rate of water existing on the land. The hydraulic system for hydroelectric power generation is constructed such that a dam or a water tank is installed in a place where there is a lot of water, the water is introduced, and the power and electricity are generated by rotating the turbine by using the flow rate and dropping amount of the introduced water.

수력기계에 사용되는 수차는 그 형식에 따라서 물의 운동에너지를 주로 사용하는 충동형 수차와 물의 압력에너지를 주로 사용하는 반동형 수차가 있다. 또한, 물을 저장하기 위한 댐을 상부와 하부에 설치하여 전기가 부족할 경우에는 상부댐에서 하부댐으로 물을 방수하여 수차 기능으로 발전하는 것과 전기가 남을 경우에 하부댐의 물을 상부댐으로 양수하는 펌프 기능을 동시에 할 수 있는 펌프수차가 있다.The aberrations used in hydraulic machines are impulsive aberrations mainly using kinetic energy of water and recoil aberrations mainly using pressure energy of water according to their types. In addition, when a dam for storing water is installed on the upper and lower sides, when the electricity is insufficient, the upper dam develops water by water from the lower dam and develops as an aberration function, and when the electricity is left, There are pump aberrations that can function simultaneously.

이중 충동형 수차에 해당되는 횡류수차는 다른 수차에 비하여 구조물이 간편하고 사용이 용이하여 널리 사용되고 있다. 이러한 횡류수차는 전기를 발생시키기 위하여 회전축에 다수 개의 회전판을 결합시키고 회전판에 복수 개의 러너깃을 결합된다. 이에 따라, 물이 판상의 러너깃에 충돌되면서 회전판 및 회전축을 회전시킴으로써 전기를 발생시키게 된다.The transverse aberration corresponding to the double impulsive aberration is widely used because the structure is simple and easy to use as compared with other aberrations. Such a transverse aberration combines a plurality of rotary plates on a rotary shaft to generate electricity, and a plurality of runners on a rotary plate. Accordingly, electricity is generated by rotating the rotating plate and the rotating shaft while the water collides with the plate-shaped runner feathers.

그러나 상기 회전판에 결합되는 러너깃은 통상적으로 25매 이상이 결합되는데, 이러한 러너깃을 일정한 치수 조건에 일치하여 제작하지 않으면 동적 불균형으로 인한 효율 저하, 수명단축, 소음 및 진동 등의 문제가 발생된다.However, if more than 25 runners are coupled to the rotary plate, unless the runners are fabricated in accordance with certain dimensional conditions, problems such as efficiency deterioration, shortened life span, noise and vibration are caused .

따라서, 횡류 수차에 사용되는 러너는 작동시 동적 불균형이 발생되지 않도록 러너깃의 조립시 상당한 주의가 요구되고 있는 실정이다.Therefore, in order to prevent dynamic imbalance during operation, the runner used for the cross flow aberration is required to pay considerable attention when assembling the runner feather.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 복수 개의 러너깃의 조립시 소수의 러너깃을 회전판에 먼저 조립하고 조립된 러너깃의 평행도를 조절한 후 나머지 러너깃을 조립하여 완성함으로써 동적 불균형을 방지할 수 있는 고성능 횡류수차 러너의 제작방법을 제공하는 데 있다.SUMMARY OF THE INVENTION The present invention has been accomplished in order to solve the above-mentioned problems, and it is an object of the present invention to provide a method of manufacturing a dynamic imbalance by assembling a plurality of runner feathers on a rotating plate, adjusting the parallelism of the assembled runner feathers, And a method of manufacturing a high-performance cross-flow aberration runner capable of preventing a high-

본 발명의 바람직한 실시예에 따른 고성능 횡류수차용 러너의 제작방법은 러너(100)의 제작시 회전판(120)에 결합되는 러너깃(130)의 결합방식을 개선함으로써 러너(100)의 작동시 동적 불균형의 발생을 방지하고 작업생산성을 높일 수 있는 데 기술적 특징이 있다.The method of manufacturing a high performance transverse aural drive runner according to a preferred embodiment of the present invention improves the coupling manner of the runner feathers 130 coupled to the rotary plate 120 during manufacture of the runner 100, There is a technical feature that prevents the occurrence of imbalance and increases work productivity.

본 발명에 따른 고성능 횡류수차용 러너의 제작방법에 의하여 제작되는 고성능 횡류수차용 러너(100)는 샤프트(110), 회전판(120) 및 러너깃(130)으로 구성된다.The high performance transverse aural drive runner 100 manufactured by the method for manufacturing a high performance transverse aural drive according to the present invention comprises a shaft 110, a rotary plate 120, and a runner feather 130.

상기 샤프트(110)는 상기 회전판(120)이 결합되는 것으로 일정길이를 갖도록 구비된다. 이러한 샤프트(110)는 둘레방향을 따라 일정높이 돌출형성되는 복수 개의 안착면(112)이 구비된다. 상기 안착면(112)은 상기 샤프트(110)에 축결합되는 회전판(120)의 축결합공(122)이 삽입되는 위치이다. 즉, 상기 안착면(112)은 샤프트(110)의 길이방향을 따라 일정 간격으로 형성됨으로써 샤프트(110)와 회전판(120)의 결합시 작업자가 회전판(120)의 결합위치를 용이하게 인지할 수 있도록 한다. 이러한 안착면(112)의 배치간격은 제작하고자 하는 러너(100) 및 회전판(120)의 크기에 맞게 적절하게 설계된다.The shaft 110 is coupled to the rotating plate 120 to have a predetermined length. The shaft 110 is provided with a plurality of seating surfaces 112 protruding at a predetermined height along the circumferential direction. The seating surface 112 is a position in which the shaft coupling hole 122 of the rotary plate 120, which is shaft-coupled to the shaft 110, is inserted. That is, since the seating surface 112 is formed at regular intervals along the longitudinal direction of the shaft 110, the operator can easily recognize the joining position of the rotating plate 120 when the shaft 110 and the rotating plate 120 are coupled . The spacing of the seating surfaces 112 is appropriately designed according to the size of the runner 100 and the rotating plate 120 to be manufactured.

상기 회전판(120)은 복수 개로 구비되어 상기 샤프트(110)에 일정간격을 두고 결합되며, 상기 러너깃(130)을 고정하기 위한 것이다. 이러한 회전판(120)은 중앙부에 샤프트(110)와의 결합을 위한 축결합공(122)이 관통형성되는 원판 형상으로 구비된다. 여기서, 상기 축결합공(122)은 상기 안착면(112)의 직경과 대략 동일한 크기를 갖도록 구비될 수도 있고, 0.1mm의 공차를 갖도록 구비될 수도 있다. 이에 따라, 상기 회전판(120)은 축결합공(122)을 통하여 상기 샤프트(110)의 안착면(112)에 배치된 후 축결합공(122)의 테두리를 따라 용접함으로써 상기 샤프트(110)에 완전히 고정된다.A plurality of the rotary plates 120 are provided to the shaft 110 at predetermined intervals to fix the runner feathers 130. The rotary plate 120 is formed in a circular plate shape having a shaft coupling hole 122 for coupling with the shaft 110 through the center thereof. Here, the shaft coupling hole 122 may be formed to have substantially the same diameter as the diameter of the seating surface 112, or may have a tolerance of 0.1 mm. The rotary plate 120 is welded to the shaft 110 by welding along the rim of the rear shaft coupling hole 122 disposed on the seating surface 112 of the shaft 110 through the shaft coupling hole 122 Completely fixed.

그리고, 상기 회전판(120)은 원주방향을 따라 테두리단으로부터 내측으로 일정깊이 절개형성되는 복수 개의 삽입홈(124)이 마련된다. 이러한 삽입홈(124)은 상기 러너깃(130)을 삽입하기 위한 것이며, 상기 러너깃(130)과 대응되는 곡선형으로 구비된다. 상기 삽입홈(124)은 정밀한 가공을 위하여 레이저 커팅으로 가공작업이 이루어지는 것이 바람직하며, 러너깃(130)의 두께보다 대략 0.1~0.2mm 더 큰 폭을 갖도록 가공된다. 여기서, 상기 회전판(120)에 형성되는 삽입홈(124)이 도면에는 26개로 구비되는 것으로 도시하였지만 이에 한정하는 것은 아니며 적절한 갯수로 설계될 수 있음을 밝혀둔다.The rotary plate 120 is provided with a plurality of insertion grooves 124 which are formed at a predetermined depth in the circumferential direction from the edge to the inside. The insertion groove 124 is for inserting the runner vane 130 and is provided in a curved shape corresponding to the runner vane 130. The insertion groove 124 is preferably machined by laser cutting for precise machining and has a width greater than the thickness of the runner vane 130 by about 0.1 to 0.2 mm. Here, the number of insertion grooves 124 formed in the rotary plate 120 is shown to be twenty-six, but it is not limited thereto, and it can be designed to have an appropriate number.

상기 러너깃(130)은 샤프트(110)에 일정간격을 두고 배치되는 복수 개의 회전판(120)에 각각 형성되는 삽입홈(124)에 동시에 삽입되어 유동되는 물이 부딪힐 수 있도록 하는 것으로, 일정면적을 갖는 판상으로 구비된다. 이러한 러너깃(130)은 선정된 재료의 연신율을 고려하여 일반적인 판금가공방법에 따라 레이저커팅이나 쉬어링을 통하여 준비된다. 즉, 도 3에 도시된 바와 같이 일정면적을 갖는 판재(P)를 누름지그(10)와 고정지그(20) 사이에 배치시킨 후 누름지그(10)를 하부측으로 이동시켜 가압함으로써 일정곡률을 갖는 형태로 벤딩한다. 여기서, 상기 고정지그(20)에는 바닥면이 소정의 곡률을 갖는 안착홈(22)이 절개형성된다. 이와 같은 벤딩작업을 통하여 가공된 러너깃(130)은 그라인딩 작업을 통하여 끝부위의 형상가공을 수행하고 필요시 기계가공을 추가하여 마무리하도록 한다.The runner feathers 130 are simultaneously inserted into the insertion grooves 124 formed in the plurality of rotary plates 120 disposed at predetermined intervals on the shaft 110 so that the flowing water can be struck, As shown in Fig. The runner feathers 130 are prepared by laser cutting or shearing in accordance with a general sheet metal working method in consideration of the elongation of the selected material. 3, the plate material P having a predetermined area is disposed between the pressing jig 10 and the fixing jig 20, and then the pressing jig 10 is moved to the lower side to press the plate material P, Bend in the form. In the fixing jig 20, a seating groove 22 having a predetermined curvature is formed on the bottom surface. Through the bending operation, the processed runner vane 130 performs shape machining of the end portion through grinding and finishes by adding machining if necessary.

본 발명에 따른 고성능 횡류수차용 러너의 제작방법은 상기와 같이 샤프트(110), 회전판(120) 및 러너깃(130)을 사전에 준비한 상태에서 먼저, 복수 개의 회전판(120)을 축결합공(122)을 통하여 샤프트(110)로 삽입한 후 각각의 회전판(120)이 샤프트(110)의 안착면(112)에 배치하여 가조립한다. 이후, 회전판(120)에 각각 형성된 복수 개의 삽입홈(124) 중 적어도 2개소 이상에 상기 러너깃(130)을 삽입하여 복수 개의 회전판(120)을 연결하도록 한다. 바람직하게는 대략 90도의 간격을 이루도록 4개의 러너깃(130)을 삽입한다. 이후, 상기 삽입홈(124)에 삽입된 4개의 러너깃(130)과 회전판(120)과의 조립평행도를 관찰하여 정확한 평행을 이루도록 조절한다. 삽입된 4개의 러너깃(130)의 조립평행도가 균형을 이룬 상태에서 상기 축결합공(122)의 테두리와 샤프트(110)의 안착면을 용접함으로써 복수 개의 회전판(120)을 샤프트(110)에 완전히 고정시킨다. 이와 같이 회전판(120)과 샤프트(110)의 용접이 끝나면 나머지 삽입홈(124)에 러너깃(130)을 차례로 삽입한 후 용접을 통하여 완전히 고정시킨다.A method for manufacturing a high performance transverse aural drive runner according to the present invention is a method for manufacturing a high performance transverse aural drive runner in which a plurality of rotary plates 120 are first assembled into a shaft coupling hole (not shown) with the shaft 110, the rotary plate 120 and the runner feather 130 prepared in advance, 122 are inserted into the shaft 110, and the respective rotary plates 120 are disposed on the seating surface 112 of the shaft 110 to cooperate. Thereafter, the runner vanes 130 are inserted into at least two of the plurality of insertion grooves 124 formed in the rotation plate 120 to connect the plurality of rotation plates 120. Preferably, four runner vanes 130 are inserted to provide an interval of approximately 90 degrees. Thereafter, the assembling parallelism of the four runner fingers 130 inserted into the insertion groove 124 and the rotary plate 120 is observed and adjusted to be in an exact parallel state. A plurality of rotary plates 120 are welded to the shaft 110 by welding the rim of the shaft coupling hole 122 and the seating surface of the shaft 110 in a state where the assembled parallelism of the inserted four runners 130 is balanced. Fully tighten. When welding of the rotary plate 120 and the shaft 110 is finished, the runner vanes 130 are inserted into the remaining insertion grooves 124 in order, and then completely fixed by welding.

이와 같이 본 발명에 따른 고성능 횡류수차용 러너의 제작방법은 복수 개의 러너깃(130)을 회전판(120)에 결합시키는 과정에서 일부 러너깃(130)을 회전판(120)에 가조립한 후 조립평행도를 맞춰 균형을 이루도록 한 후 완전히 고정함으로써 러너(100)의 작동시 동적 불균형으로 인한 제반문제를 사전에 방지할 수 있게 된다. 또한, 모든 구성품을 사전에 정확한 치수로 미리 제작한 후 간단한 조립 및 용접을 통하여 완성시킴으로써 작업생산성을 높일 수 있게 된다.
