A wind turbine component ( 18 ) includes an inner member ( 32 ) and an outer member ( 34 ) disposed relative to the inner member ( 32 ), wherein the inner and outer members ( 32, 34 ) move relative to each other. A plain bearing ( 200 ) is coupled to one of the inner or outer member ( 32, 34 ) and configured to provide a fluid film ( 202 ) for maintaining separation of and facilitating relative movement between the inner and outer members ( 32, 34 ). A position adjustment mechanism ( 78 ) is coupled to the one of the inner or outer member ( 32, 34 ) for selectively moving the plain bearing ( 200 ). A position controller ( 176 ) may be operatively coupled to the position adjustment mechanism ( 78 ) for controlling the position of the plain bearing ( 200 ). The wind turbine component may be a wind turbine generator ( 18 ) with the inner member and outer member corresponding to one of the stator and rotor assemblies ( 32, 34 ). Methods for controlling the generator are also disclosed. |
