The invention provides a hub vortex eliminating mechanism for a ship thruster, and relates to the technical field of ship thrusters, the hub vortex eliminating mechanism comprises a pod, and a propeller is arranged in the middle of the right end of the pod; a hub vortex eliminating assembly is arranged at the left end of the nacelle and comprises a flow guide pipe, the flow guide pipe is located in the middle of the left end of the nacelle, the flow guide pipe and the nacelle are connected through multiple sets of flow guide blades, and the number and the angle of the flow guide blades are arranged according to flow field distribution of hub vortexes; the bottoms of the multiple groups of guide vanes are fixedly mounted on the outer surface of the pod, and the tail ends of the multiple groups of guide vanes are connected with the inner side surface of the guide pipe; the flow guide pipe and the multiple groups of flow guide blades are fixed by welding; and the blade sections of the guide blades are wing-shaped. By arranging the hub vortex eliminating assembly, circumferential vortexes appearing near the hub part can be fully eliminated, and by means of the circumferential energy of the vortexes to be dissipated, the axial energy is increased, the axial thrust is improved, and the efficiency of the propeller is improved.
本申请提供了一种用于船舶推进器的毂涡流消除机构,涉及船舶推进器技术领域,包括吊舱,吊舱的右端中部设置有螺旋桨;吊舱的左端设置有毂涡消除组件,包括导流管,导流管位于吊舱的左端中部,导流管与吊舱之间通过多组导流叶片进行连接,导流叶片的数量和角度根据毂涡的流场分布进行布置;多组导流叶片的底部固定安装在吊舱的外表面,多组导流叶片的末端与导流管的内侧面进行连接;导流管与多组导流叶片之间均采用焊接进行固定;导流叶片的叶剖面呈机翼型。本发明通过设置毂涡消除组件,可以充分消除毂部附近出现的周向涡,利用即将耗散掉的涡的周向能量,实现轴向能量的增加,提高轴向的推力,提升推进器的效率。
