Beschreibung
Zusammenfassung:	The present invention relates to a device used for a wind turbine, particular to a pivotal bearing of a servo actuating device used on the rotor head of the wind turbine. A connecting part 23 is positioned among blades, a first and second bearing rings 13, 15 and extend relative to bearing rings connected therewith. At least one of the first and second bearing rings 13,15 is connected with the connecting part 23 but not connected with the blades 5c by the connecting part. The present invention is preferably used for large-power wind turbine.
