WIND-DRIVEN POWER UNIT Russian patent published in 2011 - IPC F03D1/00 

FIELD: power industry.

SUBSTANCE: wind-driven power unit includes wind wheel with horizontal rotation axis rigidly connected to the post having the possibility of windward orientation by being turned about vertical axis, and roller fixed on outlet shaft of wind-driven power unit, which forms together with the wind wheel rim the friction couple with mutual pressure force proportional to value of the moment developed with windwheel. In addition, it is equipped with two rollers offset along the windwheel rim in relation to the roller to both sides through 120°; at that, all the three rollers contact with end surface of the rim, which is located on downwind side, and their axes are rigidly connected to the post. Mutual pressure of contact surfaces is performed with front pressure of wind owing to giving to windwheel the possibility of being offset along its axis.

EFFECT: improving reliability of wind-driven unit owing to simplifying kinematic diagram.
