TAPER WIND MOTOR Russian patent published in 2006 - IPC F03D3/00 

FIELD: wind-power engineering; application in regions at low wind velocities.

SUBSTANCE: proposed taper wind motor has revolving frame mounted in fixed housing; mounted turnably on this frame are turnable shaft and blade shafts which are connected with gear trains at constant ratio of angular velocities of 2:1. Vane is rigidly secured on turnable shaft; shafts of blades are mounted on frame in inclined position; transmission from shafts of blades to turnable shaft is made in form of gearing through idlers; half of gear wheels mounted on turnable shaft are provided with hubs; they may turn through 180°; hubs have longitudinal slots; turnable shaft is hollow and is provided with profiles slot and splines in lower part; mounted inside this shaft is rod with pin received by profiled slot; mounted turnably on opposite end of rod is splined bush with stop received by splines of turnable shaft; mounted in fixed housing is translational motion drive with movable actuating member connected with end of rod for relative turn.

EFFECT: enhanced reliability due to automatic orientation of blades relative to wind flow; reliable protection of wind motor against overloading in case of gale.
