The invention relates to the technical field of ship design, particularly to a stern shaft support of a ship.The tail shaft support is used for supporting a propulsion shafting of the ship, the end, located at the tail of the ship, of the propulsion shafting is connected with a propeller, the tail shaft support is arranged at the end, close to the propeller, of the propulsion shafting, one end ofthe tail shaft support is connected to the propulsion shafting, and a preset distance is formed between the tail shaft support and the propeller. The other end of the tail shaft support is connected with a ship body, inclines towards the head of the ship and forms a first preset angle with the propulsion shafting. The technical scheme provided by the invention has the beneficial effects that the structure is simple; the invention provides a novel tail shaft support. The tail shaft support inclines towards the head of the ship so as to increase the distance between the tail shaft support and the propeller, meanwhile, the external expansion angle of the first support and the external expansion angle of the second support of the tail shaft support are designed to be larger than 1 degree, theinfluence of the shaft support on follow current is effectively reduced, and the propelling efficiency of the propeller is improved.

    本发明涉及船舶设计技术领域,尤其涉及一种船舶的尾部轴支架,用于支撑船舶的一推进轴系,推进轴系位于船舶的尾部的一端与一螺旋桨连接,尾部轴支架设置于推进轴系靠近螺旋桨的一端,尾部轴支架的一端连接于推进轴系,并与螺旋桨之间具有一预设距离;尾部轴支架的另一端连接一船体,并朝向船舶的首部倾斜,与推进轴系形成一第一预设角度。本发明技术方案的有益效果在于:本发明提供一种新型的尾部轴支架,通过将尾部轴支架向船舶首部倾斜,以增加尾部轴支架与螺旋桨之间的距离,同时,将尾部轴支架的第一支架和第二支架的外扩角设计为大于1°,有效降低轴支架对伴流的影响,并增大螺旋桨的推进效率。
