The invention relates to a boat propeller which includes a gear box, an impeller, a stream-guiding ring, and a stream-shaping nozzle. The gear box has a casing and a transmission shaft partially received in the casing. The impeller has an impeller shaft and vanes. The impeller shaft has a hollow columnar outer shaft housing and a hollow columnar inner shaft housing. The inner and outer shaft housings are connected using a plurality of rib portions. The inner shaft housing is further connected to the transmission shaft of the gear box. The vanes are integrated formed on an outer peripheral surface of the outer shaft. The stream-guiding ring is assembled to the casing of the gear box to house the impeller. The stream-shaping nozzle is connected to a rear end of the stream-guiding ring for providing stream-shaping effects. Thereby, the boat propeller has its water inlet diameter maximized, which helps to improve propulsive efficiency.
本发明有关于一种船用推进器,其包含有一个齿轮箱、一个叶轮、一个导流环及一个整流喷嘴。齿轮箱具有一个箱体与一个局部穿设于箱体的传动轴,叶轮具有一个轮轴与多个叶片,轮轴具有一个呈中空圆管状的外轴壳及一个呈中空圆管的内轴壳,内、外轴壳之间利用多个肋部连接在一起,其中的内轴壳再与齿轮箱的传动轴作连接,叶片一体成形于外轴壳的外周面,导流环设于齿轮箱的箱体且将叶轮罩住,整流喷嘴连接导流环的后端,用于提供整流效果。因此,本发明的船用推进器让有效进水直径最大化,以达到提升推进效率的目的。
