Abstract
A wind driven turbine having a plurality of wind wheels mounted on a single drive shaft supported rotatably on a turntable at the upper end of a supporting framework with a plurality of wind wheels being mounted on opposite ends of the single horizontal shaft. The horizontal shaft is drivingly connected to a vertical shaft which drives a generator assembly at the lower end of the supporting framework. A wind vane assembly is connected to the turntable and a governor assembly is drivingly connected to the horizontal shaft for controlling the rotational speed of the wind wheels and horizontal shaft.
Claims6
A wind turbine assembly comprising a supporting framework including a rigid elevated platform, a turntable rotatably supported from said platform for swivelling movement about a substantially vertical axis, a horizontal shaft rotatably journalled from the turntable with the end portions of the shaft projecting diametrically therefrom, a plurality of wind wheels mounted on each end of the horizontal shaft outwardly of the turntable for rotating the shaft in response to axial flow of wind through the wind wheels, the area peripherally of said wind wheels being unconfined to provide unrestricted and untrapped wind flow in relation to the wind wheels, a vertical shaft supported from the framework and drivingly connected to the horizontal shaft, a generator assembly supported at the lower end of the framework and being drivingly connected to the vertical shaft, a wind rudder connected with the turntable for maintaining the rotational axis of the horizontal shaft generally parallel to the wind direction, and governor means driven from the horizontal shaft for increasing the load on the vertical drive shaft by the generator assembly in response to the rotational speed of the horizontal shaft above a predetermined rpm for preventing over-speeding of the wind wheels.
