Provided are a propulsion apparatus for a ship and a ship including the same. According to an embodiment of the present invention, the propulsion apparatus for a ship comprises: a rear propeller fixed to a rotation shaft; a front propeller rotationally supported on the rotation shaft in the front of the rear propeller; an inverse rotation device inverting rotation of the rotation shaft to be transmitted to the front propeller, which is accommodated in a tail of a hull; a propeller connection member connecting the inverse rotation device and the front propeller to transmit a rotation force; and a bearing assembly installed between a hub of the front propeller and the rotation shaft. Moreover, the bearing assembly comprises: an internal side support ring fixated to an outer surface of the rotation shaft; an external side support ring installed in an outer side of the internal side support ring in a state of being spaced from the internal side support ring, and fixated to an inner surface of the hub of the front propeller; and a rear thrust bearing installed between the internal side support ring and the external side support ring.
선박용 추진장치 및 이를 갖춘 선박을 개시한다. 본 발명의 실시 예에 따른 선박용 추진장치는 회전축에 고정된 후방프로펠러; 후방프로펠러 전방의 회전축에 회전 가능하게 지지된 전방프로펠러; 회전축의 회전을 반전시켜 전방프로펠러로 전달하며 선체 후미에 수용되는 반전회전장치; 반전회전장치와 전방프로펠러를 연결하여 회전력을 전달하는 프로펠러 연결부재; 및 전방프로펠러의 허브와 회전축 사이에 설치되는 베어링조립체를 포함하며, 베어링조립체는 회전축 외면에 고정되는 내측지지링과, 내측지지링과 이격 상태로 내측지지링 외측에 설치되며 전방프로펠러 허브 내면에 고정되는 외측지지링과, 내측지지링과 외측지지링 사이에 설치되는 후방추력베어링을 포함한다.
