The present invention relates to an electro-hydraulic actuator applied steering device for a ship, which comprises: a hydraulic cylinder part driven by movement of an operating fluid; a main block fixedly connected to the hydraulic cylinder part to be related to a direction where the operating fluid flows; a servo-motor part fixedly installed on one side of the main block to provide a rotational force; a reservoir part fixedly installed on the other side of the main block to store and discharge the operating fluid introduced from the main block and compensating for a flow rate due to a volume difference generated when a single rod of the hydraulic cylinder part is moved forward and backward; a hydraulic pump part fixedly installed on one side of an interior of the reservoir part and driven by receiving a rotational force from the servo-motor part; an electric hydraulic actuator connected to an exterior side part of the reservoir part and having a temperature maintaining part for uniformly maintaining a temperature of the operating fluid in the reservoir part; and a driving control part of an electro-hydraulic actuator, which accurately adjusts an angle of a tiller and a rudder connected to the electro-hydraulic actuator through a hinge to control the heading of a ship and maintains the temperature of the operating fluid.

    본 발명은 전기 유압 액추에이터를 적용한 선박용 조타장치에 관한 것으로서, 작동유의 이동으로 구동되는 유압실린더부와, 유압실린더부와 고정하여 연결되어, 작동유 흐름의 방향을 관여하는 메인블럭과, 메인블럭의 일측에 고정 설치되어, 회전력을 제공하기 위한 서보모터부와, 메인블럭의 다른 일측에 고정 설치되어, 메인블럭으로부터 유입되는 작동유를 저장 또는 배출시키며, 유압실린더부의 편로드의 전진 또는 후진 시 발생하는 부피차에 의한 유량을 보상하기 위한 저유기부와, 저유기부의 내부 일측에 고정 설치되어, 서보모터부로부터 회전력을 제공받아 구동되는 유압펌프부와, 저유기부의 외측부에 연결 설치되어, 저유기부의 내부에 있는 작동유의 온도를 일정하게 유지하기 위한 온도유지부를 구비하는 전기 유압 액추에이터와, 선박의 진행방향을 조정하도록 전기 유압 액추에이터와 힌지 연결되는 틸러와 방향타의 앵글을 정밀하게 조정하며 작동유의 온도를 유지하는 전기 유압 액추에이터의 구동제어부를 포함하는 것을 특징으로 한다.
