摘要： In one aspect, a dual pitch bearing 60,100,120 configuration for coupling a rotor blade 20 to a hub of a wind turbine 10 is provided. The dual pitch bearing configuration including a first pitch bearing 62 and at least one additional pitch bearing 64. The first pitch bearing 62 and the and at least one additional pitch bearing 64 are coupled to opposed surfaces of a static shaft 74. The at least one additional pitch bearing 64 is disposed radially a distance L R and axially a distance L A from the first pitch bearing 62 along the static shaft 74. The dual pitch bearing 60,100,120 is disposed radially within a blade root of the rotor blade 20. The dual pitch bearing configuration minimizing moment loading on the first pitch bearing 62 and the at least one additional pitch bearing 64. A wind turbine 10 including the dual pitch bearing 60,100,120 configuration is further disclosed.
