Beschreibung
Zusammenfassung:	The invention describes a blade pitch arrangement (1) of a wind turbine having a number of blade shafts (22) extending radially outward from a hub (20) and a rotor blade (21) mounted around each blade shaft (22), which blade pitch arrangement (1) comprises a toothed ring (11) arranged at the root end (210) of each rotor blade (21); and a pitch drive unit (10) for each rotor blade (21), comprising a driver body (102) and a pinion (101) realised to engage with the toothed ring (11) of a rotor blade (21); characterized in that a pitch drive unit (10) is arranged relative to its corresponding rotor blade (21) such that the pinion (101) is positioned closest to the hub (20), and the driver body (102) extends in a direction radially outward from the hub (20). The invention further describes a wind turbine.
