The invention discloses a marine composite material propeller blade connecting structure and a forming method thereof. The marine composite material propeller blade connecting structure comprises a propeller hub, a propeller blade connecting wing plate and a propeller blade composite material skin, the propeller blade connecting wing plate and the propeller hub are integrally formed by adopting the same material, the propeller blade composite material skin completely wraps the outer portion of the propeller blade connecting wing plate, and the end of the propeller blade composite material skin extends into a groove of the propeller hub. And the end part of the blade composite material skin is adhered and fixed with the groove of the propeller hub through a sealant. According to the composite propeller blade connecting structure for the ship, the propeller hub and the propeller blade connecting wing plates are integrally formed, the propeller blade connecting wing plates are wrapped with the propeller blade composite skin, and the ends of the propeller blade composite skin are contained in the propeller hub, so that the forming precision of the propeller is guaranteed, and vibration and noise generated when the propeller works can be reduced.
本发明公开了一种船用复合材料螺旋桨叶片连接结构及其成型方法。本船用复合材料螺旋桨叶片连接结构,包括桨毂、桨叶连接翼板以及桨叶复合材料蒙皮,桨叶连接翼板和桨毂采用同种材质一体成型,桨叶复合材料蒙皮完全包裹于桨叶连接翼板外部且其端部延伸至桨毂的凹槽中,桨叶复合材料蒙皮的端部通过密封胶与桨毂的凹槽粘贴固定。本发明提出的船用复合材料螺旋桨叶片连接结构,因桨毂和桨叶连接翼板一体成型,再将桨叶复合材料蒙皮包裹于桨叶连接翼板外部并端部容纳于桨毂中,从而保证了本螺旋桨的成型精度,进而可减少螺旋桨在工作时产生的震动和噪音。
