The invention discloses an auxiliary exhaust type marine propeller, and relates to the technical field of marine power systems. The propeller comprises a blade cylinder, blades, a spiral connecting rib plate, a central transmission shaft, a limiting block and a mounting threaded block. According to the design scheme, the exhaust passage structure of the propeller is optimized; a connecting rib plate of the propeller transmission center and the propeller blade cylinder is designed into a spiral rib plate; when the rotating speed of an engine reaches the standard rotating speed of 5000 to 6000 RPM, engine exhaust can be effectively assisted, damage to the engine due to unsmooth exhaust is avoided; and meanwhile, engine exhaust gas is rotationally sprayed out through the spiral exhaust structure and converted into thrust, engine oil consumption can be effectively reduced, the engine is protected, and the cruise speed of a ship is increased.

    本发明公开了一种辅助排气式船用螺旋桨,涉及船用动力系统技术领域,包括叶片筒、叶片、螺旋状连接筋板、中心传动轴、限位块、安装螺纹块。本发明设计方案本发明通过优化螺旋桨的排气通道结构,将螺旋桨传动中心与螺旋桨叶片筒的连接筋板设计为螺旋形筋板,使得发动机转速达到标准转速5000‑6000RPM时,可以有效地辅助发动机排气,避免排气不畅对发动机造成的损伤,同时螺旋排气结构将发动机废气旋转喷出,转化为推力,能够有效的降低发动机油耗,保护发动机的同时,提高了船舶巡航速度。
