Abstract
A wind turbine rotor includes a hub, a plurality of blades, and a pitch system for rotating a blade substantially along its longitudinal axis. The pitch system includes a bearing, a motor, and a gear system, wherein the gear system has a driving pinion operationally connected with the motor, an annular gear arranged to mesh with the driving pinion. Additional gear teeth are arranged to mesh with other parts of the gear system in a predefined blade position for wind speeds at or below a nominal wind speed such that upon movement from the predefined blade position, the additional gear teeth come into contact with the other parts of the gear system before the driving pinion comes into contact with the annular gear.
