PLANETARY TRANSMISSION FOR WINDMILL GENERATOR Russian patent published in 2010 - IPC F03D9/00 

FIELD: engines and pumps.

SUBSTANCE: proposed transmission comprises base, electric generator and windmills consisting of two wind wheels fitted on common shaft. Fist of said wheels is rigidly linked with support shaft mounted on said base, while another wheel runs on support shaft and comprises transition elements that make a set of identical planetary mechanisms. Support shaft of the second wind wheel comprises pinion frame with radial link to be aligned with first triangular rotor side surface pin furnished with coaxial crank arranged off-center on support shaft with their ratio between their radii making 3:2 and eccentricity making half the radius of sun gear. Said triangular rotor side surface pin is articulated with pinion frame link, said pinion frame being secured on drive sun gear. Final sun gear is engaged with generator, while unit of annular rings/crowns with their inner outline representing epitrochoids delineated by crests of triangular rotors is rigidly linked with second wind wheel.

EFFECT: higher efficiency of windmill.
