The invention belongs to the technical field of outboard engines, and particularly relates to a toothless outboard engine which comprises a power flange, a flywheel cover is arranged on one side of the power flange, a telescopic stand column assembly is arranged on one side of the flywheel cover, a lower box body is arranged on one side of the telescopic stand column assembly, and taper couplings are arranged on the two sides of the lower box body. The propeller is in threaded connection with the coupling, and a buoy intercooler is arranged on one side of the lower box body. The buoy intercooler is arranged on the device body, and the buoyancy and cooling function of the buoy intercooler are utilized, so that the weight of the lower box body on the device body in water is reduced, and the danger of the propeller in water is reduced. Due to the fact that no gear or synchronous belt is adopted for transmission, the contact area is increased, a high-horsepower outboard engine (1200 hp or above) can be manufactured, meanwhile, the taper coupling is adopted, impact resistance is achieved, operation is stable, high-speed reversing is suitable, the adaptability of a product is improved, and the service life of the product is prolonged.
本发明属于舷外机技术领域,尤其为一种无齿舷外机,包括动力法兰,所述动力法兰的一侧设置有飞轮罩,所述飞轮罩的一侧设置有伸缩立柱组件,伸缩立柱组件的一侧设置有下箱体,所述下箱体的两侧均设置有锥度联轴节,螺旋桨与联轴节螺纹连接,所述下箱体的一侧设置有浮筒中冷器。本发明通过在装置本体上设置浮筒中冷器,利用浮筒中冷器的浮力和冷却功能,减轻装置本体上的下箱体在水中的重量和降低螺旋桨在水中受到的危险性。由于不采用齿轮或同步带传动,接触面积增大,可以制造大马力舷外机(1200hp以上),同时又采用锥度联轴节,耐冲击,运转平稳,适合高速换向,提高了产品的适应能力和使用寿命。
