Each blade wraps around vertical axle and has a radial width that increases from its upper portion to its lower portion while supporting an open brow section forming a cup-like space with webbed like stiffeners section.
Abstract:
This invention discloses the efficient, non-polluting generation of electricity through the construction and use of an electric power generating system wherein electricity is generated by utilizing the powerful subsurface undercurrents present near an ocean shoreline. The undercurrent water is caused to cycle internally through a conical shell housing assembly constructed in an upwardly narrowing configuration to produce a nozzle effect within the shell housing. The nozzle effect generates a combined water and air power piston that alternates in a vertical direction within the shell assembly. In both the upward and downward cycles, the power piston impacts a fan blade component that causes the shaft of an electricity generating turbine to rotate and produce electricity.
Abstract:
A vertical axis wind generator structure includes a tower, a windmill assembly, a bearing assembly, a lubrication assembly, and a generator. The windmill assembly is installed on the bearing assembly. The windmill assembly and the bearing assembly are rotatably sleeved on a shaft lever of the tower. The bearing assembly provides for thermal expansion compensation and axial and radial loading. The lubrication assembly supplies lubricating oil based on the operating conditions of the windmill assembly so as to prolong the lifespan and improve the electricity generation effect of the wind generator.

Abstract:
A tapered roller bearing (31a) has a plurality of retainer segments (11a, 11d) each having a pocket to house a tapered roller (34a), and arranged so as to be continuously lined with each other in a circumferential direction between an outer ring (32a) and an inner ring (33a). The retainer segment (11a, 11d) is formed of a resin containing a filler material to lower a thermal linear expansion coefficient. In addition, a clearance (39a) is provided between the first retainer segment (11a) and the last retainer segment (11d) after the plurality of retainer segments (11a, 11d) have been arranged in the circumferential direction without providing any clearance. Here a circumferential range (R) of the clearance (39a) is larger than 0.075% of a circumference of a circle passing through a center of the retainer segment (11a, 11d) and smaller than 0.12% thereof at room temperature.
Abstract:
The present invention discloses an article of manufacture comprising a conical helicoid wind turbine. The conical helicoid is configured such that its apex faces toward the on-coming wind which allows airflow to transverse through the curved sail from the front center to the outer rear extremity. This dynamic shape produces the optimum amount of force by distributing the wind load to the outer edges of the wind turbine's rotation. In addition, by channeling the flow of air through the conical helix to convert to motive force, the turbine forces the wind into a vortexual formation which entrains wind flow in tandem with the turbine's rotational force, thus reducing backflow turbulences.
Abstract:
Electrical-energy generator of the type that incorporate a plinth or pedestal from which emerges a vertical, fixed shaft on which is mounted, via bearings, a second shaft to which a blade of conical, helicoidal shape is secured, which imparts a rotary movement to the movable shaft through the effect of the wind, characterized in that said fixed shaft is tubular and incorporates within it an electrical winding functioning as stator, whilst the movable shaft, which is also tubular, incorporates within it a plurality of permanent magnets that convert it into a rotor, all the aforesaid in such a manner that the actual shaft of the generator simultaneously constitutes the dynamo or the alternator that converts the mechanical energy into electrical energy.
Abstract:
The present invention is related to rotor blade for a wind energy plant, with a blade root, with a first longitudinal portion starting from the blade root, with a second longitudinal portion, following up the first longitudinal portion and running into a blade tip, with a first surface, facing a tower of the wind energy plant in its assembled state, and a second surface, facing away from the tower of the wind energy plant in its assembled state, wherein an imaginary reference plane is spanned up by a rotation, taking place in the operation of the rotor blade, of the longitudinal axis of the first longitudinal portion around the rotational axis of a rotor of the wind energy plant carrying the rotor blade. The objective to provide a rotor blade which has a high efficiency even at safe prevention of collisions of the blade tip with the tower of the wind energy plant, and in which the moments around the longitudinal blade axis occurring in the operation are reduced, is resolved by the invention in that the first surface runs along an imaginary cone plane in the region of the second longitudinal portion, which is spanned up by a rotation, taking place in the operation, of the first surface in the region of the second longitudinal portion around the rotational axis of a rotor carrying the rotor blade, wherein the cone plane intersects the reference plane in an angle, and that the distance between the first surface and the reference plane along the second longitudinal portion increases linearly in the direction towards the blade tip, and that the second longitudinal portion is longer than the first longitudinal portion. In addition, the present invention is related to a wind energy plant.
