摘要:
A segmented gear plate configured to be removably connected to a pitch bearing of a wind turbine has been described. The pitch bearing is present between a rotor hub and a plurality of blades. The pitch bearing axially pivots the plurality of blades between different pitch angles. The pitch bearing includes an inner bearing ring and an outer bearing ring rotatably interconnected to each other. The segmented gear plate is removably connected to at least one of the inner bearing ring or the outer bearing ring by at least one connecting element. The segmented gear plate having a plurality of gear teeth, the plurality of gear teeth configured to allow the rotation of a drive shaft of a motor to achieve different pitch angles.
