The invention discloses a novel marine propeller which comprises a propeller mounting cylinder; a plurality of centrosymmetric radian spiral propeller blades are fixedly arranged on the inner wall of the propeller mounting cylinder, a rotating shaft is fixedly arranged at one end of the propeller mounting cylinder through a connecting piece, and a bearing is fixedly arranged on the rotating shaft in a sleeving mode; the rotating shaft and the propeller mounting cylinder are mounted on the outer side of a ship body, and the bearing is fixedly connected with the ship body. Compared with an existing propeller, the propeller has the following advantages that the contact surface is larger, the borne resistance is smaller when the rotating speed is increased, and the technical concept of energy conservation and environmental protection is met.
本发明公开了一种新型船用螺旋桨,包括螺旋桨安装筒,所述的螺旋桨安装筒内壁固定设置有多个中心对称的弧度螺旋形的螺旋桨片,所述的螺旋桨安装筒的一端通过连接件固定设置有旋转轴,所述旋转轴上固定套接设置有轴承,所述的旋转轴和螺旋桨安装筒均安装在船体的外侧,所述的轴承与船体固定连接。本发明具有如下优点:相对于现有的螺旋桨来说,接触面更大,且在转速增大的时候,受到的阻力更小,符合节能环保的技术理念。
