Turbo-machine with blade wheels

摘要

A turbo-machine with blade wheels, comprises a body, a rotor which is held in a rotatable manner by the body, at least two rotatably arranged blades which are distributed uniformly along a circular line of the rotor and which are mounted with their axis parallel to the axis of the rotor, transmission members between each axis of the blade and a sleeve which is rotatable on the shaft of the blade wheel. The first rotor is assigned a second rotor which is held in a rotatable manner by the first rotor, wherein the second rotor comprises at least two rotatably arranged blades which are distributed uniformly along a circular line of the rotor and which are mounted with their axis parallel to the rotor, transmission members between each axis of the blade and the sleeve which is rotatable on the shaft of the rotor.

主权项

1. A fluid dynamic machine with blade rotors, comprising:
a body; a first rotor rotatably housed by the body, the first rotor being rotatable about a main axis, comprising: at least two first blades rotatably provided on the first rotor, uniformly distributed along a circumference of the first rotor, each first blade being supported on a respective first blade axle which is parallel to and spaced apart from the main axis, each first blade being rotatable about an axis of said first blade axle; and first transmission member rotatably connecting each first blade axle to a sleeve rotatable on a power shaft of the rotor; the first rotor being associated with a coaxial second rotor rotatably housed by the first rotor, the second rotor being rotatable about said main axis, the second rotor comprising: at least two second blades rotatably provided on the second rotor, uniformly distributed along a circumference of the second rotor, each second blade being supported on a respective second blade axle which is parallel to and spaced apart from the main axis, each second blade being rotatable about an axis of said second blade axle; and second transmission member rotatably connecting each second blade axle and the sleeve rotatable on the power shaft, so that the angular position of said second blades is rigidly linked to the angular position of said first blades through said first and second transmission members and said sleeve; and a third transmission member rotatably connecting at least one among said first and second rotors to said power shaft.
