The invention discloses a rudder-propeller matching system, which comprises a rudder arranged below a fake rudder, a rudder ball fixed on the front end face of the rudder, a propeller located on the same horizontal line with the rudder ball, and a reduction gear box connected with the propeller through a tail shaft, wherein a propeller cap is installed at the tail end of the propeller, a gap is formed between the propeller cap and the rudder ball, and the shape of the surface, which faces the rudder ball, of the propeller cap is matched with the line type of the rudder ball. Cavitation bubblesare avoided, instant impact and corrosion caused by cavitation bubble breaking are avoided, and the service life of the rudder and the service life of the propeller are prolonged.
本发明公开了一种舵桨匹配系统,包括设置在假舵下方的舵、固定在舵的前端面上的舵球、与舵球处于同一水平线上的螺旋桨、以及通过尾轴与螺旋桨相连的减速齿轮箱,螺旋桨的尾端安装有桨帽,桨帽与舵球之间设置有间隙,桨帽的面向舵球的面的形状与舵球的线型相匹配。本发明避免空泡的产生,避免空泡破灭造成的瞬间冲击和腐蚀,提高了舵和螺旋桨的使用寿命。
