Abstract
The drive device is provided for inclusion in a windmill with two counter-rotating screws. The shafts of the screws are each connected to a spindle of an epicyclical gearbox, the third spindle providing the energy for the user. The device further comprises a brake device simultaneously acting on the two shafts of the screws. In particular, said device permits the installation of a second screw on a windmill mast designed for a single screw on a windmill mast designed for a single screw, thus greatly increasing the power supplied.
