The invention relates to the field of propellers, in particular to a ship propeller. The impeller comprises a front impeller, a rear impeller, a shell assembly, an outer transmission shaft, an inner transmission shaft, a driving mechanism a used for driving the outer transmission shaft to rotate and a driving mechanism b used for driving the inner transmission shaft to rotate. The outer transmission shaft is provided with a mounting channel allowing the inner transmission shaft to penetrate through, the outer transmission shaft and the inner transmission shaft are rotationally arranged on the shell assembly, the rotating directions of the outer transmission shaft and the inner transmission shaft are opposite, the front impeller is arranged at the end of the inner transmission shaft and provided with twisted blades a, and the rear impeller is arranged at the end of the outer transmission shaft. The rear impeller is provided with blades b with the twisting direction opposite to that of the blades a, the multiple blades a and the multiple blades b are annularly arrayed, and the driving mechanism a and the driving mechanism b are both arranged in the shell assembly. According to the invention, the propulsive force can be increased, and the propulsive force to the ship can be continuously maintained when one impeller is damaged.

    本发明涉及推进器领域,具体为船用推进器。其包括前叶轮、后叶轮、外壳组件、外传动轴、内传动轴、用于驱动外传动轴转动的驱动机构a以及用于驱动内传动轴转动的驱动机构b;外传动轴具有供内传动轴贯穿的安装通道,外传动轴和内传动轴均转动设置在外壳组件上,外传动轴和内传动轴转动方向相反,前叶轮设置在内传动轴端部,前叶轮具有扭曲的叶片a,后叶轮设置在外传动轴端部,后叶轮具有与叶片a扭曲方向相反的叶片b,叶片a和叶片b均环形阵列多个,驱动机构a和驱动机构b均设置在外壳组件内。本发明能加大推进力且能在一个叶轮损坏时继续保持对船的推进力。
