The drive device is provided for inclusion in a windmill with two counter-rotating screws (10, 100, 11). The shafts (12, 13) of the screws are each connected to a spindle (17, 18) of an epicyclical gearbox, the third spindle (19) providing the energy for the user (8). The device further comprises a brake device (15) 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, thus greatly increasing the power supplied. |
