Abstract:
In one aspect, a dual pitch bearing configuration for coupling a rotor blade to a hub of a wind turbine. The dual pitch bearing configuration including a first pitch bearing and at least one additional pitch bearing disposed axially a distance LB from the first pitch bearing. The dual pitch bearing configuration further including one or more spacers disposed between the first pitch bearing and the at least one additional pitch bearing and extending the distance LB. The dual pitch bearing disposed radially within one of a blade root of the rotor blade, a hub extension or a bearing housing and coupled thereto. The dual pitch bearing configuration minimizing moment loading on the first pitch bearing and the at least one additional pitch bearing. A wind turbine including the dual pitch bearing configuration is further disclosed.
