본 고안은 선박이 추진될때 스크류에 받은 저항을 최대한으로 적게 받으면서도 추진력이 증대되게 한 선박용 스크류에 관한 것으로, 종래에도 추진력을 증대시킨 스크류를 얻고져 현재 사용되고 있는 스크류의 각도에 주안점을 두어 연구 해왔으나 종래의 스크류의 형태가 변형되지 못하였기 때문에 추진력을 크게 증대시키지 못하고 그의 마찰력을 감소시킬 수 없었다. 현재 사용되고 있는 스크류의 날개는 축심부로부터 일정 지점까지는 회전 속도에 따라 물의 저항만을 받을 뿐 추진력에는 도움을 주지 못하여 많은 동력소모를 해왔던 것이다.The present invention relates to a ship screw that allows the propulsion force to be increased while receiving the least resistance received by the screw when the ship is propelled. Since the shape of the conventional screw was not deformed, the propulsion force could not be greatly increased and its friction force could not be reduced. The blade of the screw currently used has a lot of power consumption because it receives only water resistance according to the rotational speed from the shaft portion to a certain point but does not help propulsion.
본 고안은 이와 같은 결점을 적게하기 위하여 스크류의 회전력에 의하여 날개가 착설된 축심부로 물이 모여 물기둥을 이루듯이 압력을 받아 전방으로 밀어주게 하는 동시에 날개의 끝은 종래와 같이 물을 전방으로 박차주게 하기 위하여 날개가 형성된 모양을 나팔상으로 하여 일측으로 점차 호형 경사각을 두면서 축심부에 부착되게 하므로서 날개의 전체에서 추진력을 얻을 수 있게 구성한 것으로, 이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.In order to reduce the drawbacks of the present invention, the water is pushed forward by the pressure of the screw into the axial center where the blades are installed by the rotational force of the screw to form a water column, and the tip of the wing spurts the water forward as before. In order to give the shape that the wings are formed in the shape of a trumpet to be attached to the axial center while having an arc-shaped inclination angle gradually to one side, it is configured to obtain the driving force in the whole of the wings, which will be described in detail by the accompanying drawings as follows.
축심체(1)의 주벽에 그 하단이 응착되고 호형각에 따라 점차 넓어지는 간격 (a)(a')(a'')을 이루도록 나팔 모양의 날개(2)(2')(2'')를 형성하고 그 선단(B) (B') (B'')을 종래의 스크류와 같이 뒤틀리게 형성하여서 된 것이다.Trumpet-shaped wings (2) (2 ') (2' 'so as to form a gap (a) (a') (a ''), the lower end of which adheres to the circumferential wall of the shaft core 1 and gradually widens according to the arc angle. ) And its tip (B) (B ') (B' ') is twisted and formed like a conventional screw.
이상과 같이된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention as described above is as follows.
나팔상의 날개(2)(2')(2'')가 축심체(1) 주벽에 그 하단부는 전체가 용착되고 축심체(1)의 상단에 이를 때까지는 호형각에 따라 점차 넓어지는 간격(a)을 이루도록 용착하고 나팔상의 날개(2)(2')(2'')의 선단은 종래의 스크류 선단 모양으로 형성하였기 때문에 스크류가 회전할 때 나팔상의 전체 내주벽에 부딛침 물은 축심부로 물기둥과 같이 모이게 되므로 이 중심부에서 큰 압력이 발생하게 되므로 이 압력이 배를 밀어주는 추진력으로 바뀌어진다.The gap between the flared wings (2) (2 ') (2' ') is gradually widened according to the arc angle until the lower end is welded to the main wall of the shaft core 1 and reaches the upper end of the shaft core 1 ( Weld to achieve a) and the tip of the flared wings (2) (2 ') (2' ') is formed in the shape of a conventional screw tip, so that when the screw rotates, the water hitting the entire inner circumferential wall of the trumpet As they gather together like a column of water, a large pressure is generated in the center, and this pressure is converted into a driving force for pushing the ship.
실시예시도에서와 같이 나팔상의 날개(2)(2')(2'')의 내면에서는 전체적으로 추진력을 발생시키게 되므로 불필요한 마찰 손실을 최대한으로 줄이게 되어 적은 힘으로 쾌속을 얻을 수 있게 한 것으로, 실시 예시도에서 보는 바와 같이 종래의 스크류는 날개의중앙부로 부터 선단에 이르기 까지는 물을 밀어내는 추진력이 발생하나 중앙부로부터 축심부까지는 마찰력만 발생할 뿐 추진력에는 오히려 저해요인이 되고 있었다.As shown in the embodiment, the inner surface of the flared wings 2, 2 ', and 2 " generates propulsion force as a whole, thereby reducing unnecessary friction loss to the maximum, thereby achieving rapid speed with less force. As shown in the illustration, the conventional screw has a driving force that pushes water from the center of the wing to the tip, but only a frictional force is generated from the center to the shaft, which is a deterrent to the driving force.
본 고안은 이와 같은 결점을 최대한으로 줄이고 추진력을 최대한으로 증대시켜 준 것인 바, 적은 힘으로 쾌속을 얻을 수 있는 이점이 있고, 스크류가 전체적으로 균일하게 마찰력이 발생되기 때문에 스크류가 부분적으로 파손되는 일이 없게 한 것이다.The present invention is to reduce such defects to the maximum and to increase the propulsion force to the maximum, there is an advantage to obtain a rapid speed with a small force, the screw is partially broken because the friction force is generated uniformly as a whole. There would be no.
