Abstract
A method of assembling a wind turbine. The method includes coupling a pitch bearing to a hub that includes a wall. The pitch bearing includes a plurality of sets of pitch bearing teeth. At least one blade is coupled to the pitch bearing such that the blade is rotatable about a pitch axis. A plurality of pitch gearbox brackets are coupled to the hub wall. A pitch drive system is selectively coupled to one of the plurality of pitch gearbox brackets, wherein a predetermined set of pitch bearing teeth are in contact with the pitch drive system.

A method of assembling a wind turbine, said method comprising:
- coupling a pitch bearing to a hub that includes a wall, the pitch bearing including a plurality of sets of pitch bearing teeth;
- coupling at least one blade to the pitch bearing such that the blade is rotatable about a pitch axis;
- coupling a plurality of pitch gearbox brackets to the hub wall;
- and,
- selectively coupling a pitch drive system to one of the plurality of pitch gearbox brackets, wherein a predetermined set of pitch bearing teeth are in contact with the pitch drive system.
A pitch assembly for use in a wind turbine, said pitch assembly comprising:
- a pitch bearing rotatably coupled to a hub, said pitch bearing comprising a plurality of sets of pitch bearing teeth;
- a plurality of pitch gearbox brackets coupled to a wall of the hub;
- and,
- a pitch drive system coupled to one of said plurality of pitch gearbox brackets to selectively contact a predetermined set of pitch bearing teeth.
A wind turbine system, comprising:
- a hub comprising a wall;
- a pitch bearing rotatably coupled to said hub, said pitch bearing comprising a plurality of sets of pitch bearing teeth;
- at least one rotor blade coupled to said pitch bearing;
- a plurality of pitch gearbox brackets coupled to said hub wall;
- and,
- a pitch drive system coupled to one of said plurality of pitch gearbox brackets to selectively contact a predetermined set of pitch bearing teeth.
