The invention discloses a propeller and a ship with the same. The propeller is used for the ship, the ship comprises a propeller shaft, the propeller comprises propeller hubs, the propeller hubs are used for being arranged on the periphery of the propeller shaft in a sleeving mode, at least two blade sets are arranged on the outer surface of each propeller hub, a gap is formed between every two adjacent blade sets in the axis direction of the propeller hub, each blade set comprises a plurality of blades arranged in the circumferential direction of the axis of the propeller hub, the multiple blades of each blade set are located at the same position in the axis direction of the propeller hub, the blade sets comprise a front blade set and a rear blade set, the blades of the front blade set incline towards the first direction relative to the axis direction of the propeller hub, and the blades of the rear blade set incline towards the second direction opposite to the first direction. Therefore, the at least two blade sets share the load for driving the ship to sail together, and the load of a single propeller is reduced, so that the tail shock phenomenon of the ship is reduced, and the probability of shattering ship body components due to the tail shock phenomenon is further reduced.

    本发明公开了一种螺旋桨及具有其的船舶。螺旋桨用于船舶,船舶包括桨轴,螺旋桨包括桨毂,桨毂用于套设至桨轴的外周,每个桨毂的外表面设置有至少两个叶片组,沿桨毂的轴线方向,相邻的叶片组之间有间隔,每个叶片组包括绕桨毂的轴线周向设置的多个叶片,每个叶片组的多个叶片位于沿桨毂的轴线方向的同一位置,叶片组包括前叶片组和后叶片组,相对于桨毂的轴线方向,前叶片组的叶片朝向第一方向倾斜,后叶片组的叶片朝向和第一方向相反的第二方向倾斜。由此,这样至少两个叶片组共同分担驱动船舶航行的负载,减小单个螺旋桨的负载,因此减少船舶的尾震现象,进而减少由于尾震现象震裂船体构件的概率。
