摘要:
A blade pitch arrangement of a wind turbine is provided having a number of blade shafts extending radially outward from a hub and a rotor blade mounted around each blade shaft, which blade pitch arrangement includes a toothed ring arranged at the root end of each rotor blade; and a pitch drive unit for each rotor blade, having a driver body and a pinion realized to engage with the toothed ring of a rotor blade; wherein a pitch drive unit is arranged relative to its corresponding rotor blade such that the pinion is positioned closest to the hub, and the driver body extends in a direction radially outward from the hub. A wind turbine is also described.
