ABSTRACT:
A wind turbine with two rotors equipped with wings, which are mounted on horizontal shafts rotatably mounted in a bearing unit. The rotors are displaced 180.degree. in relation to each other. The bearing unit is connected to a rotatably mounted vertical output shaft with the rotor shaft projecting substantially radially on diametrically opposite sides of the output shaft, gear wheels of the rotor shafts engaging a gear ring mounted coaxially with the output shaft stationarily in relation to the output shaft. A second pair of rotors of the same type as the first pair are mounted on shafts which are rotatably mounted in the bearing unit perpendicularly to the shafts of the first pair of rotors and are displaced 180.degree. in relation to one another and 90.degree. in relation to the first pair of rotors. A gear train interconnects the rotors for position-synchronized rotation.
