Fig. 1 and Fig. 2 are please referred to, the present invention provides a kind of technical solution: a kind of novel propeller propeller hub, including propeller hub 1, lead
Frame 2, oil cylinder cover 3, blade packing 4, sliding block 5 and stern tube shaft 6, propeller hub 1 are fixedly connected with oil cylinder cover 3 by oil cylinder screw 9, oil cylinder cover
3 on the left side wall of propeller hub 1, and propeller hub 1 is fixedly connected with stern tube shaft 6 by flange screw 7, and stern tube shaft 6 is located at the right side of propeller hub 1
On wall, sliding block 5 is slidably connected with saddle 2, and sliding block 5 is located on the sliding slot of 2 outer wall of saddle, blade packing 4 and the fixed company of saddle 2
It connects, and is located at the outside of saddle 2.
In the present embodiment, by setting propeller hub 1, saddle 2, oil cylinder cover 3, blade packing 4, sliding block 5 and stern tube shaft 6, have
The frame of a whole propeller is constituted to effect, because sliding block 5 is located on the sliding slot of 2 outer wall of saddle, makes entire propeller
Running basis well is provided, facilitating propeller can be promoted towards each required direction.
Further, the chamber between 3 inner wall of 2 left end of saddle and oil cylinder cover is positive vehicle oil pocket 11；2 right end of saddle is led with insertion
Chamber between 6 end of stern tube shaft of 2 inner cavity of frame is reversing oil pocket 12.
In the present embodiment, it is arranged at different locations respectively with oil cylinder cover 3 and stern tube shaft 6 respectively by the way that saddle 2 is arranged
Cavity provides different accommodation spaces for propeller, provide the foundation for the multi-direction propulsion of propeller.
Further, the root of blade packing 4 is provided with pin, and pin insertion sliding block 5 is flexibly connected with sliding block 5.
In the present embodiment, by the way that blade packing 4 is arranged, and its root is provided with pin, thus pin insertion sliding block 5
In, it is flexibly connected for it with sliding block 5.
