<P>PROBLEM TO BE SOLVED: To provide a wind power generator that a gear body can be designed at a level of an on-driving maximum load without losing necessary strength and durability, when a rolling bearing including a fixed gear is used in a slewing ring bearing to engage with a driving gear. <P>SOLUTION: The wind power generator is located on an upper end of a tower where a nacelle is vertically arranged on a base. The generator includes: a yaw driving device for yawing the nacelle; and/or a pitch driving device for controlling a pitch angle of a windmill blade. The yaw driving device and/or the pitch driving device are/is equipped with an engagement part between the slewing ring bearing 20 including an inner tooth or an outer tooth and a pinion gear, and a driving mechanism of the devices includes a clutch mechanism which slips by receiving larger input than the on-driving maximum load to the engagement part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
