Abstract
The invention relates to turbo-engine having a variable-pitch propeller. An adjustment spindle is disposed inside the shaft that carries the variable-pitch propeller. The adjustment spindle is connected to a step-down transmission, which is affixed in the area of the face side of the motor that drives the variable-pitch propeller or at a driven generator, and which interacts with an adjustment motor.
Claims7
A turbine assembly having a variable-pitch propeller for interacting with a fluid, and an adjustment mechanism that controls the pitch angle of the variable-pitch propeller, said turbine assembly comprising:
- a drive motor having a hollow rotor shaft including a first end which is connected to said variable-pitch propeller and a second remote end which is disposed opposite to said first end;
- an adjustment motor located adjacent to said second remote end of said hollow rotor shaft, said adjustment motor being disposed remote from said fluid;
- and
- an adjustment spindle rotatably located within said hollow shaft and being connected to both said shaft of said adjustment motor and said pitch angle adjustment mechanism so that rotation of said adjustment motor is transmitted through said hollow shaft to said adjustment mechanism to adjust the pitch angle of said propeller blades.
