Abstract

본 발명은 선박의 추진 효율을 극대화 시킬 수 있는 나선형 스크류에 관한 것으로 종래의 프로펠러형 스크류의 문제점인 낮은 효율성과 소음 문제를 해결하기 위한 것이다.The present invention relates to a spiral screw that can maximize the propulsion efficiency of the ship to solve the problem of low efficiency and noise, which is a problem of the conventional propeller type screw.

본 발명은 직선상의 스크류축(1)상에 길이 방향으로 용착시킨 나선형 날개(2)로 스크류(3)를 형성하여 스크류축에 인가된 동력에 의해 스크류가 회전하면서 쐐기 형태로 물을 파고 들면서 추진되도록 한 구성을 갖는다.The present invention forms a screw (3) with a spiral blade (2) welded in the longitudinal direction on a straight screw shaft (1), and while the screw is rotated by the power applied to the screw shaft while digging water in the form of wedge propulsion Have one configuration as possible.

본 발명에 의한 나선형 스크류는 스크류가 물을 파고 들면서 스크류를 발생시켜 추진하는 구조를 갖기 때문에 스크류회전에 따른 마찰력을 최소로 할 수 있고, 저속RPM하에서 큰 추진력을 얻을 수 있고, 고속추진이 가능하며, 스크류 회전시의 소음을 최소화 시킬수 있는 효과를 갖는다.Since the spiral screw according to the present invention has a structure in which the screw is generated by pushing the screw while digging water, the frictional force due to the screw rotation can be minimized, a large propulsion force can be obtained under a low speed RPM, and the high speed propulsion is possible. It has the effect of minimizing the noise during screw rotation.

Claims (1)

직선상의 스크류축(1)상에 길이 방향으로 용착시킨 나선형 날개(2)로 스크류(3)를 구성함으로써 스크류축에 인가된 동력에 의해 스크류가 회전할 때 쐐기 형태로 물을 파고 들면서 수류를 발생시켜 선박을 추진하도록 한 것을 특징으로 하는 선박의 나선형 스크류.By constructing the screw 3 with the spiral blade 2 welded in the longitudinal direction on the straight screw shaft 1, water flow is generated by digging water in the shape of a wedge when the screw rotates by the power applied to the screw shaft. Spiral screw of the ship, characterized in that to propel the ship. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
