Abstract
The invention relates to an adjustment device for variable-pitch propellers or turbo-engines. A drivable rotor is mounted on a hollow flange of a shaft that is connected to the variable-pitch propeller. The rotor is rotatably mounted on the hollow flange, and its inside diameter has a formation which interacts with intermediate wheels and gears mounted in the hollow flange.
Claims6
An adjustment device for adjusting a pitch angle of at least one blade of a variable-pitch propeller of a turbo-engine comprising:
- a shaft having a hollow range;
- a gear transmission being disposed within said hollow flange;
- a propeller being fastened on the shaft;
- and
- an annular rotary member having a rotational axis is mounted on and is disposed radially outside of the hollow flange, the rotary member has an inner cylindrical surface facing the rotation axis that has a formation for transmitting torque, the formation is connected to said gear transmission so as to transmit force, and said rotary member being driven by a stator.
