  • Hybrid wind turbine blade bearing
    Patent number: 9011010
    Abstract: Wind turbine blade pitch bearing device (1) adapted for rotational support of a turbine blade (9), having a first bearing unit (4, 5) and a second bearing unit (6, 7) coaxial to the first bearing unit. The first bearing unit (4, 5) and the second bearing unit (6, 7) are of different bearing types. By using two different bearing types, one bearing can be optimized for small and quick rotations and the other type can be optimized for larger and slower rotations.
