Device for adjustment of rotor blades of the rotor in a wind power system

Between the blade (6) and the rotor hub a tubular section (8) is fitted. At the upper end the section is linked to the blade by a roller bearing (18) the inner ring (19) of which engages with a motor (21) driven pinion (20). This arrangement is duplicated and the motors are controlled to adjust the...

Zusammenfassung:Between the blade (6) and the rotor hub a tubular section (8) is fitted. At the upper end the section is linked to the blade by a roller bearing (18) the inner ring (19) of which engages with a motor (21) driven pinion (20). This arrangement is duplicated and the motors are controlled to adjust the blade angle in unison. The power for operating the motors can be electrical, hydraulic or mechanical ( using the rotational energy of the rotor.
