Abstract
The invention relates to a wind driven generator, in particular to an eccentric bush which can adjust a variation paddle mechanism of a wind driven generator and an assembly method of the eccentric bush. The eccentric bush which can adjust the variation paddle mechanism is installed in a guiding hole of a variation paddle adjusting frame, a guiding rod is installed in the inner hole of the eccentric bush, the diameter of the outer ring of the eccentric bush corresponds to that of the guiding hole of the variation paddle adjusting frame in a matching way, the inner ring of the eccentric bush is provided with a size matched with the guiding rod, and the eccentric distance of the diameter of the inner ring with respect to the diameter of the outer ring of the eccentric bush is 0.1 to 0.2 millimeters. The invention also provides the assembly method of the eccentric bush. Through adopting the technical proposal, the wind driven generator completely solves the problems that the standard requirements of the axiality, the parallelism and the position degree between the assembled guiding rod and the guiding hole of the variation paddle adjusting frame are difficult to meet, and the clamping phenomenon occurs during the movement of the variation paddle adjusting along the guiding rod.
