Embodiment Construction

[0021] figure 1 A side view of the wind power plant 1 with its basic components is shown. The wind power plant 1 has a tower 15 on which a nacelle 16 in the form of a machine housing is arranged so as to be rotatable about a vertical axis. A planetary gear 2 is fastened in the gondola 16 in a rotationally fixed manner, wherein the planetary gear 2 has a drive shaft 5 and an output shaft 6 . The drive shaft 5 of the planetary gear 2 is connected to a hub 17 of a rotor 4 with a plurality of rotor blades 18 . The driven shaft 6 is connected in rotation to a drive to be driven in the form of a generator 3 .

[0022] The planetary gear 2 is designed such that it converts a slow rotation of the drive shaft 5 into a fast rotation of the output shaft 6 . To this end, the planetary gear 2 has one or more planetary gear stages, which interact with the output shaft 6 via a closed spur gear. Electric energy is generated by means of a wind power plant 1 by introducing the rotation, wh...
