Beschreibung
Zusammenfassung:	A system for a wind turbine comprising a pitch system comprising a blade pitch bearing (52) and a wind turbine hub (51), the pitch bearing being attached to the wind turbine hub (51) and arranged to be attachable to a wind turbine rotor blade (53). A pitch gear (57), having a gear surface (13) for engaging with an actuator such as a pinion (54), is releaseably coupled to the pitch system so that the pitch gear, under the action of the actuator, causes relative rotation between the hub and the relevant part of the bearing. Releasably coupling the gear surface to the pitch system can allow easy replacement of the gear without requiring the removal of large components such as the bearing.
