Abstract
A nacelle for a wind power installation, a rotor for a wind power installation, a wind power installation, use of a planetary-gearbox-free electric actuator drive, a method for wind direction tracking of a nacelle, and a method for rotor blade adjustment of rotor blades of a rotor are provided. Provided is a nacelle for a wind power installation, in particular a wind power installation having a nominal output of more than 3000 kilowatts (kW), having at least one azimuth drive which is used for the wind direction tracking of the nacelle and which is configured as a planetary-gearbox-free electric actuator drive.
Claims13
A nacelle for a wind power installation having a nominal output of more than 3000 kilowatts (kW), comprising:
- at least one azimuth drive that is a planetary-gearbox-free electric actuator drive and configured to track a wind direction of the nacelle, the planetary-gearbox-free electric actuator drive including a first toothed-pin gearbox stage and a second toothed-pin gearbox stage having a higher gearing than the first toothed-pin gearbox stage, wherein the second toothed-pin gearbox stage includes:
- a plurality of toothed pins that are movable;
- and
- a profiled disk, wherein the plurality of toothed pins are disposed on a radial circumferential face of the profiled disk on an end of the profiled disk facing away from an input shaft or an output shaft, wherein the plurality of toothed pins perform a translatory movement radial to the input shaft or the output shaft, and wherein a force transmission from the input shaft to the output shaft is performed by the translatory movement of the plurality of toothed pins.
A rotor for a wind power installation having a nominal output of more than 3000 kilowatts (kW), comprising:

- a plurality of toothed pins that are movable;
- and
- a profiled disk, wherein the plurality of toothed pins are disposed on a radial circumferential face of the profiled disk on an end of the profiled disk facing away from an input shaft or an output shaft, wherein the plurality of toothed pins perform a translatory movement radial to the input shaft or the output shaft, and wherein a force transmission from the input shaft to the output shaft is performed by the translatory movement of the plurality of toothed pins;
- driving a sprocket;
- and
- rotating the nacelle about a rotation axis of the nacelle.
A method for rotor blade adjustment of a plurality of rotor blades of a rotor of a wind power installation having a nominal output of more than 3000 kilowatts (kW), comprising:
- actuating at least one planetary-gearbox-free electric actuator drive including a first toothed-pin gearbox stage and a second toothed-pin gearbox stage having a higher gearing than the first toothed-pin gearbox stage, wherein the second toothed-pin gearbox stage includes:
- a plurality of toothed pins that are movable;
- and
- a profiled disk, wherein the plurality of toothed pins are disposed on a radial circumferential face of the profiled disk on an end of the profiled disk facing away from an input shaft or an output shaft, wherein the plurality of toothed pins perform a translatory movement radial to the input shaft or the output shaft, and wherein a force transmission from the input shaft to the output shaft is performed by the translatory movement of the plurality of toothed pins;
- driving a sprocket;
- and
- rotating a rotor blade of the plurality of rotor blades about a longitudinal axis.
