Pitch bearing for wind turbine rotor blades

摘要

A pitch bearing for a wind turbine rotor (5) comprises a rotor hub (7) and at least one rotor blade (9), the pitch bearing comprising a cylindrical inner bearing ring (13) connectable to a rotor blade (9) of the wind turbine rotor (5), a cylindrical outer bearing ring (15) connectable to the rotor hub (7) of the wind turbine rotor (5) and an annular reinforcement section (21) for reinforcing the outer bearing ring (15). The annular reinforcement section (21) adjoins the cylindrical outer bearing ring (15) at its radial outer surface.
