Mounting of rotors for wind energy converters having a vertical rotor arrangement

摘要

Mounting of rotors for wind energy converters having a vertical rotor mast arrangement, the mounting comprising an upper and a lower rotor bearing, an energy generating unit which can be driven by the rotor and positive-locking coupling means for torque transmission from the rotor to the driven unit via shafts coaxial with one another, the lower mounting (3') for supporting the rotor mast (6) taking place by means of a spherical roller bearing (40, 41, 42, 43) and the transmission of the torque from the rotor (2) to the elements to be driven taking place by means of a positive-locking coupling (16) in the manner of a curved-tooth coupling and the centre (P) of the oscillating motion of the axial spherical roller bearing (3') lying in the central plane (E-E) of the curved toothing (16; 33, 34).
