ABSTRACT:
A vertical-axle wind power machine comprises a vertical axle, a plurality of jointed radial arms, a plurality of counterbalanced oblique blades at the support points thereof, a friction-rewarding rotary speed multiplying transmission, and an automatic rotary speed regulating means to be performed by either a wind-operated or an alternative digital controlled rotary speed regulating device; the combination of which provides the oblique blades with great sensitivity to the alternation of lee wind and head wind for automatic swinging to the most efficient lee angle at upstanding and overturned positions to sail nearly three quarters and streamline against the head wind resistance for the remaining quarter every circle of rotation, is able to convert the centripetal and centrifugal component forces to the same torque direction of the tangential component force from the same blade by an eccentric-guided angular bracket means and a fork-rooted radial arm, is able to offset the friction loss in the rotary speed multiplying process by pairs of bushed multiplying gears serially coupled between a pair of paralleled vertical shafts in connection with the vertical axle, and is able to output a stable and desired rotary speed by either a wind-operated or an electronically controlled rotary speed regulating device regardless the variable wind speed.
