선박 계류용 앵커는 체인에 연결되어 바다에 투척되거나 인양된다. 이러한 앵커의 체인은 앵커용 윈치의 드럼에 권취되어 필요에 따라 풀려나오거나 되감긴다. The mooring anchor is connected to the chain and is thrown into the sea or salvaged. The chain of these anchors is wound on the drum of the anchor winch and unwound or rewound as necessary.

앵커 체인이 감기는 윈치드럼은 종래에는 주조되어 성형되었다. 그런데 주조 소재 및 성형기법상의 한계에 의해 윈치드럼의 전체적 중량이 무거웠고 그 무게만큼 제조비용이 증대되었다. 또한 주조에 사용되는 소재는 부식에 취약하고 내마모성이 떨어지며, 특히 극지방과 같은 극저온의 환경에서는 더욱 내구성이 떨어지는 문제점이 있었다. The winch drums with the anchor chain winding are conventionally cast and molded. However, the overall weight of the winch drum was heavy due to limitations in the molding material and molding machine, and the manufacturing cost was increased by the weight. In addition, the materials used for casting are vulnerable to corrosion and abrasion resistance, and in particular, they are less durable in a cryogenic environment such as a polar region.

따라서, 본 발명의 목적은 경량화로 제조비용을 감소시키는 동시에, 부식에 강하고 저온 내구강도가 우수한 앵커 윈치드럼을 제공하는 것이다.Accordingly, an object of the present invention is to provide an anchor winch drum which is light in weight and low in manufacturing cost, and which is resistant to corrosion and excellent in low temperature durability.

도 1은 본 발명에 따른 앵커 윈치드럼(10)의 사시도이고, 도 2는 전동기어휠(310)이 장착되기 전 앵커 윈치드럼(10)의 분해 사시도이고, 도 3은 전동기어휠(310) 장착되기 전 윈치드럼(10) 결합상태를 나타내는 확대 단면도이다.2 is an exploded perspective view of the anchor winch drum 10 before the transmission gear wheel 310 is mounted and FIG. 3 is an exploded perspective view of the transmission gear wheel 310, Fig. 8 is an enlarged cross-sectional view showing a state of engagement of the winch drum 10 before being mounted.

도 1, 2 및 3에 도시된 바와 같이, 앵커 윈치드럼(10)은 드럼본체(100)를 중심으로 드럼본체(100)의 일단면에 브레이크지지플레이트(200)가 결합되며, 타단면에 기어지지플레이트(300)가 결합된다. 1, 2 and 3, the anchor winch drum 10 has a brake support plate 200 coupled to one end face of the drum body 100 with respect to the drum body 100, The support plate 300 is engaged.

드럼본체(100)는 중심부로 갈수록 직경이 작아지며 내부가 비어있는 장구와 같은 형상이다. 그래서 축선방향의 중앙영역 외표면에는 원주방향을 따라 권취그루브(110)가 형성되어 있고, 이 권취그루브(110)에 체인을 연결하여 체인을 권취 또는 권출한다. 드럼본체(100) 내부에는 외부형상에 대응하는 형태로 축선둘레를 따라 중공부(120)가 형성되어 있다. 드럼본체의 양쪽 측면에는 원주방향을 따라 플레이트결합면(130)이 존재하며, 양 쪽의 플레이트결합면(130)에 각각 브레이크지지플레이트(200)와 기어지지플레이트(300)가 결합된다. 이러한 드럼본체(100)는 주조되어 성형되며, 내부가 비어 있는 형상으로 제조되어 전체 윈치드럼(10)의 중량을 감소시킨다.The drum body 100 has a shape that is smaller in diameter toward the center and has an interior hollow shape. Thus, on the outer surface of the central region in the axial direction, a winding groove 110 is formed along the circumferential direction, and a chain is connected to the winding groove 110 to wind or unwind the chain. Inside the drum body 100, a hollow portion 120 is formed along the axial line in a shape corresponding to the outer shape. The brake supporting plate 200 and the gear supporting plate 300 are coupled to both plate coupling surfaces 130 on both sides of the drum body. The drum body 100 is cast and formed, and the inside thereof is formed in an empty shape to reduce the weight of the entire winch drum 10.

드럼본체(100)의 축선방향으로 일단면에는 브레이크지지플레이트(200)가 용접 또는 체결볼트 등으로 결합된다. 브레이크지지플레이트(200)는 드럼본체(100)의 일단면 원주의 직경을 일정 수준 넘어서는 원판 형상이다. 원판의 중심점에는 축공이 형성되어 있고, 이 축공을 중심으로 방사상으로 복수의 보강리브(140)를 가진다. 보강리브(140)는 축공 방향에서 브레이크지지플레이트(200)의 원주까지 형성되어 있다. 이와 같은 보강리브(140)는 브레이크지지플레이트(200)와 브레이크드럼(210)의 결속력을 높이는 한편, 브레이크지지플레이트(200)에 가해지는 외력을 분산하는 역할을 한다. 보강리브(140)가 결합된 상태에서 브레이크지지플레이트(200)의 원주방향을 따라서 브레이크드럼(210)이 결합되며, 이를 통해 회전하는 윈치드럼(10)을 정지시킨다.The brake supporting plate 200 is coupled to one end face of the drum body 100 in the axial direction by welding or fastening bolts. The brake supporting plate 200 is in the form of a disk having a diameter exceeding a certain circumferential diameter of one end surface of the drum body 100. A shaft hole is formed at the central point of the disk, and a plurality of reinforcing ribs 140 are radially formed around the shaft hole. The reinforcing ribs 140 are formed from the axial direction to the circumference of the brake support plate 200. The reinforcing ribs 140 serve to increase the coupling force between the brake support plate 200 and the brake drum 210 and to disperse the external force applied to the brake support plate 200. The brake drum 210 is coupled along the circumferential direction of the brake support plate 200 in a state where the reinforcing ribs 140 are engaged to thereby stop the rotating winch drum 10. [

드럼본체(100)의 축선방향으로 타단의 플레이트결합면(130)에는 기어지지플레이트(300)가 용접 또는 체결볼트 등으로 결합된다. 기어지지플레이트(300) 역시 드럼본체(100)의 일단면 원주의 직경을 일정 수준 넘어서는 원판 형상이다. 원판의 중심에는 축공이 형성되어 있으며, 이 축공을 중심으로 방사상으로 복수의 보강리브(140)를 갖는다. 다만 기어지지플레이트(300)의 보강리브(140)는 브레이크지지플레이트(200)상의 보강리브(140)와 달리 축공에서부터 원주까지 형성되어 있지 않고, 원주에서 축공방향으로 소정거리 이동된 위치까지 형성되어 있다. 이로 인해 기어지지플레이트(300) 원주와 보강리브(140)사이에 평탄면이 존재하며, 이 평탄면에 전동기어휠(310)이 장착된다.The gear support plate 300 is coupled to the plate coupling surface 130 at the other end in the axial direction of the drum body 100 by welding or fastening bolts. The gear support plate 300 is also in the form of a disk having a diameter exceeding the diameter of one end surface circumference of the drum body 100 by a predetermined level. A shaft hole is formed in the center of the disk, and a plurality of reinforcing ribs 140 are radially formed around the shaft hole. The reinforcing rib 140 of the gear support plate 300 is not formed from the shaft hole to the circumference unlike the reinforcing rib 140 on the brake support plate 200 and is formed to a position shifted by a predetermined distance in the axial direction from the circumference have. As a result, a flat surface exists between the circumference of the gear support plate 300 and the reinforcing rib 140, and the transmission gear wheel 310 is mounted on the flat surface.

기어지지플레이트(300) 상의 평탄면에는 다수의 체결공(350)이 형성되어 있다. 이 체결공(350)은 전동기어휠(310)의 체결공(350)에 대응하는 위치에 형성되어 있으며, 각각의 대응하는 체결공(350)들에 체결볼트를 삽입하여 전동기어휠(310)을 기어지지플레이트(300)에 결합시킨다. 이와 같이 결합된 전동기어휠(310)은 외부로부터 동력을 전달받으며, 드럼본체(100)를 회전시켜 드럼본체(100)에 연결된 체인을 권취 또는 권출되도록 한다.A plurality of fastening holes 350 are formed on the flat surface of the gear support plate 300. The fastening hole 350 is formed at a position corresponding to the fastening hole 350 of the transmission gear wheel 310 and fastening bolts are inserted into the corresponding fastening holes 350, To the gear support plate (300). The electric gear wheel 310 thus coupled receives power from the outside and rotates the drum body 100 so that the chain connected to the drum body 100 is wound or unwound.

브레이크지지플레이트(200)와 기어지지플레이트(300)는 주조 성형되는 드럼본체(100)와 달리 강판 소재로 제조된다. 여기서 사용되는 강판은 강도가 우수하고, 비바람 또는 염해 등에 의해 발생하는 부식 및 저온에 대한 내구성이 뛰어난 것으로 선택된다. 따라서 강판으로 제조되는 브레이크지지플레이트(200)와 기어지지플레이트(300)는 강한 외력을 받더라도 변형을 최소화할 수 있으며, 부식 방지효과가 우수하고, 저온 내구성이 뛰어나 쇄빙선 등 극지방을 항해하는 선박에도 적용이 용이하다. The brake support plate 200 and the gear support plate 300 are made of a steel sheet material unlike the drum body 100 to be cast. The steel sheet used here is selected to be excellent in strength, excellent in durability against corrosion caused by weathering or salt corrosion, and low temperature. Therefore, the brake support plate 200 and the gear support plate 300, which are made of a steel plate, can minimize deformation even under a strong external force, have excellent corrosion prevention effect, and are excellent in low temperature durability and are also applied to vessels navigating in polar regions such as icebreakers This is easy.

드럼본체(100) 양 단면에 브레이크지지플레이트(200)와 기어지지플레이트(300)가 결합되면 원주의 중심에 형성된 축공에 드럼축(400)을 삽입하고, 이를 결합시킨다. 드럼축(400)은 대체로 원통형상이며, 양 끝단에 윈치에 장착되기 위한 베어링장착부(410)를 가진다. 베어링장착부(410)는 드럼축(400)보다 직경이 작은 원통으로 드럼축(400)의 회전 축선방향으로 돌출되어 있는 형상으로, 베어링장착부(410)는 베어링 등과 결합하여 앵커 윈치에 설치된다. 그리고 이러한 구조로 드럼축(400)은 베어링과 결합함으로써, 베어링을 축공에 맞추어 삽입하지 않고 외부로 노출되게 장착할 수 있다. 이에 따라 윈치드럼(10)의 설치작업의 효율성을 높였고, 베어링 유지보수에 있어서도 효율적이다.When the brake support plate 200 and the gear support plate 300 are coupled to both ends of the drum body 100, the drum shaft 400 is inserted into the shaft hole formed at the center of the circumference and is engaged. The drum shaft 400 is generally cylindrical in shape and has bearing mounts 410 for mounting the winch on both ends thereof. The bearing mounting portion 410 is formed in a cylindrical shape having a diameter smaller than that of the drum shaft 400 and protrudes in the direction of the rotation axis of the drum shaft 400. The bearing mounting portion 410 is installed in the anchor winch in combination with a bearing. With this structure, the drum shaft 400 is coupled with the bearing, so that the bearing can be mounted so as to be exposed to the outside without inserting the bearing into the shaft hole. As a result, the installation efficiency of the winch drum 10 is improved and the maintenance of the bearings is also efficient.
