The invention discloses a blade rotating tool for an adjustable propeller. The blade rotating tool mainly comprises a sealing ring, an outer sleeve, an inner sleeve, a nut and a connector; the left end of the outer sleeve is installed in a middle hole of a propeller shaft, dynamic sealing is achieved through the sealing ring, and the outer sleeve can horizontally move in the middle hole of the propeller shaft; the inner sleeve is fixed in an inner hole of the outer sleeve through the nut and the sealing ring, the left end of the inner sleeve is connected with an adjustable propeller inner oilpipe through threads, and the adjustable propeller inner oil pipe can move horizontally to drive the inner sleeve to move forwards and backwards, so that the outer sleeve can move forwards and backwards in the middle hole of the propeller shaft; oil is introduced through an upper joint of the outer sleeve, pressure oil is introduced into a propeller hub oil cylinder front oil cavity at the rear end of the propeller shaft through the middle hole of the propeller shaft, a piston is pushed to move backwards, and then a propeller hub internal crank mechanism is adopted to drive blades to rotate forwards and drive the outer sleeve to move backwards; on the contrary, oil is introduced through a right end joint of the inner sleeve, pressure oil is introduced into a propeller hub oil cylinder rearcavity through the inner sleeve and an inner oil pipe to drive the blades to rotate reversely and drive the outer sleeve to move forwards. The blade rotating tool has the characteristics of simple structure, few parts, light weight, flexibility, convenience and reliability in use and the like.

    一种用于可调螺旋桨的桨叶转动工装,它主要包括密封圈、外套、内套、螺母、接头;所述外套左端安装在桨轴中孔中,通过密封圈来达到动密封,并可在桨轴中孔中水平移动;所述内套通过螺母与密封圈固定在外套内孔中,内套左端通过螺纹与可调桨内油管相连,可调桨内油管的水平移动带动内套前后移动,从而使外套在桨轴中孔中前后移动;从外套上部接头处进油,压力油通过桨轴中孔进入桨轴后端的桨毂油缸前油腔,推动活塞后移,进而通过桨毂内部曲柄机构驱动桨叶正转,同时带动外套后移;反之,从内套右端接头处进油,压力油通过内套、内油管进入桨毂油缸后油腔,驱动桨叶反转,外套前移。它具有结构简单、零件少、重量轻、使用灵活方便、可靠等特点。
