Background

Double-wind wheel wind driven generators and the technology thereof are receiving more and more attention.
In order to achieve the purpose of reducing the weight of the tower top cabin of the double-wind-wheel wind driven generator, the generator is arranged in the middle of the tower or on the ground, however, the bevel gears on the double-wind-wheel shaft can deflect and deviate from the wind direction after being damped by the load of the bevel gears on the vertical shaft (the double-wind-wheel shaft looks like a helicopter with a coaxial double-rotor wing layout, but the horizontal-to-vertical transmission of the windmill is only one group of bevel gears, so the balance cannot be realized).
The prior large horizontal windmill has an automatic wind-aligning device which consumes a small amount of electric power, but the large yawing moment is available, so that more energy is consumed to correct the deviation (similar to a tail rotor at the tail part of a single-rotor helicopter).
Therefore, how to balance the above-mentioned yaw moment is a problem to be solved.
