Abstract
A method of assembling a pitch assembly for use in a wind turbine. The method includes coupling a pitch bearing to a hub of the wind turbine, wherein the pitch bearing includes a plurality of bearing teeth. A pitch drive system is coupled to the pitch bearing such that the pitch drive system contacts a first set of bearing teeth. A plurality of bearing segments is coupled to the pitch bearing to cause the pitch drive system to selectively contact a second set of bearing teeth.

A method of assembling a pitch assembly for use in a wind turbine having a plurality of blades, said method comprising:
- coupling a pitch bearing to a hub of the wind turbine, wherein the pitch bearing includes a plurality of bearing teeth;
- coupling a pitch drive system to the pitch bearing such that the pitch drive system contacts a first set of bearing teeth;
- and,
- coupling a plurality of bearing segments to the pitch bearing to cause the pitch drive system to selectively contact a second set of bearing teeth.
A pitch assembly for use in a wind turbine including a plurality of blades, said pitch assembly comprising:
- a pitch bearing rotatably coupled to a hub of the wind turbine, said pitch bearing comprising a plurality of bearing teeth,
- a pitch drive system coupled to said pitch bearing and in contact with a first set of said plurality of bearing teeth;
- and,
- a plurality of bearing segments, at least one of said plurality of bearing segments coupled to said pitch bearing to cause said pitch drive system to selectively contact a second set of bearing teeth.
A wind turbine comprising:
- a hub;
- at least one blade configured to rotate about a pitch axis;
- a pitch bearing rotatably coupled to said hub, said pitch bearing comprising a plurality of bearing teeth;
- a pitch drive system coupled to said pitch bearing and in contact with a first set of said plurality of bearing teeth;
- and,
- a plurality of bearing segments, at least one of said plurality of bearing segments coupled to said pitch bearing for causing said pitch drive system to selectively engage a second set of bearing teeth.
