The invention discloses a ship propeller, and relates to the technical field of ship power devices. The ship propeller comprises a driving part, two propulsion assemblies which are symmetrical in structure and a clamping assembly which is used for supporting the propulsion assemblies and connected with the side edge of a ship body. A supporting frame connected with the inner bottom face of the ship body is installed in the middle of the driving part through a bearing. The adjacent end of the driving part and the adjacent ends of the propulsion assemblies are in transmission through a power connection control assembly; the driving part comprises a main shaft rod; two crankshaft parts are arranged on the main shaft rod in a central symmetry manner; first spline connecting holes are symmetrically formed in two ends of the main shaft rod; and the main shaft rod between the two crankshaft parts is rotationally connected with the supporting frame through a bearing. Through the cooperative use of the driving part, the propulsion assemblies, the clamping assembly, the supporting frame and the power connection control assembly, the ship propeller is installed on an unpowered ship, the overall structure is reasonable and simple, and the labor intensity of people is reduced.

    本发明公开了一种船舶推进器,涉及船舶动力装置技术领域。本发明包括驱动部件、结构对称的两个推进组件、以及用于支撑推进组件且与船体侧边连接的卡接组件,驱动部件中部通过轴承安装有与船体内底面连接的支撑架;驱动部件相邻端与推进组件相邻端通过动力连接控制组件传动;驱动部件包括主轴杆;主轴杆上中心对称设置有两个曲轴部;主轴杆两端对称开有第一花键连接孔;两个曲轴部间的主轴杆通过轴承与支撑架转动连接。本发明通过驱动部件、推进组件、卡接组件、支撑架和动力连接控制组件的配合使用,安装在无动力的船舶上,整体结构合理简单,降低人的劳动强度。
