The marine propeller comprises a propeller hub, propeller blades, a driving device and vortex elimination fin blades, the propeller hub comprises a propeller area and a vortex elimination fin area, through grooves matched with a first bearing disc and a second bearing disc are formed in the periphery of the propeller area and the periphery of the vortex elimination fin area respectively, the propeller blades are installed on the upper end face of the first bearing disc, and the driving device is installed on the lower end face of the second bearing disc. A first bevel gear is fixed to the lower end of the first bearing disc, vortex eliminating fins are installed on the upper end face of the second bearing disc, and a second bevel gear is fixed to the lower end of the second bearing disc. According to the marine propeller with the adjustable screw pitch and the vortex eliminating fins, the vortex eliminating fins can still eliminate bubbles when the variable propeller adjusts the screw pitch to decelerate or accelerate, the efficiency is higher, the consumed time is shorter, the energy consumption is reduced, and a better energy-saving effect is achieved; the synchronously changing vortex eliminating fins reduce noise and vibration generated by the propeller when the ship accelerates and decelerates, and the overall comfort of the ship is improved.

    本发明公开了一种船用可调节螺距的螺旋桨,包括桨毂、螺旋桨叶、驱动装置和消涡鳍叶,所述桨毂包括螺旋桨区和消涡鳍区,螺旋桨区和消涡鳍区的四周分别设置有与第一承盘和第二承盘相配合的通槽,第一承盘的上端面安装有螺旋桨叶,第一承盘的下端固定有第一锥形齿轮,第二承盘的上端面安装有消涡鳍叶,第二承盘的下端固定有第二锥形齿轮。该船用可调节螺距的螺旋桨和消涡鳍同步变化的效果,在可变螺旋桨调节螺距减速或者加速的时候,消涡鳍依然能够消除气泡,效率更高,时间用的更少,降低了能耗,具有较好的节能效果,同步变化的消涡鳍降低了船舶在加速和减速时候螺旋桨产生的噪音和振动,提高了船舶整体的舒适性。
