Abstract

본 발명은 선박을 추진하기 위한 트로펠러(Propeller)를 추진축에 고정할 때 사용하는 프로펠러 보스캡(Boss cab)에 관한 것으로 특히, 선박의 추진효율에 도움이 되는 프로펠러 보스캡에 관한 것이다.The present invention relates to a propeller boss cab used when fixing a propeller to a propulsion shaft to propel a ship, and more particularly, to a propeller boss cap that helps the propulsion efficiency of a ship.

본 발명에 따른 프로펠러 보스캡의 표면에는 소정방향으로 일정피치를 갖는 나선이 형성되어 있다. 전체적으로 여러가지 외주형상을 갖도록 구성할 수 있지만 원추형의 형상을 갖도록 하는 것이 가장 좋다.On the surface of the propeller boss cap according to the present invention, a spiral having a constant pitch in a predetermined direction is formed. Although it can be comprised so that it may have various outer peripheral shapes as a whole, it is best to have a conical shape.

이와 같은 본 발명에 따른 프로펠러 보스캡을 사용하는 선박은 프로펠러에 의한 추진력외에 부가추진력을 얻을 수 있고, 기존의 보스캡을 사용했을 때 발생되면 일부저항이 발생되지 않아 선박의 추진효율을 높일 수 있다는 효과가 있다.Such a ship using the propeller boss cap according to the present invention can obtain additional propulsion force in addition to the propulsion force by the propeller, and when generated when using the existing boss cap, some resistance is not generated can increase the propulsion efficiency of the vessel It works.
