摘要： A wind turbine assembly is provided. The assembly includes a support structure and a wind turbine mounted on the support structure. The wind turbine includes a front face with blades defining a surface area to engage incoming wind, a roll axis about which the wind turbine can rotate in response to incoming wind to drive an electric generator, where the support structure defines a horizontal tilt axis about which the wind turbine can pitch forward and backward. The tilt axis divides the surface area of the wind turbine into upper and lower portions of unequal size, such that incoming wind on the front face of the wind turbine applies unequal force to the upper and lower portions of the surface area of the wind turbine to induce pitch of the wind turbine about the tilt axis.

摘要： Drive device for a wind mill comprising a large pulley disposed on a main shaft and at least one belt or chain adapted to transfer rotation from the pulley to a generator. The pulley is rotationally coupled to at least two secondary shafts, which are disposed parallel to the main shaft. One or more belts, which transfer the rotation, extend over the pulley and the secondary shafts. The secondary shafts are in turn rotationally coupled to at least one, preferably two, electric generators.

摘要： A windmill for generating electricity is described, which contains several improvements that enable the blades of the windmill to be much wider than conventional electricity-generating windmill blades. The rotor containing the blades will also change direction to capture the largest amount of wind energy available. The windmill includes a “shroud” surrounding the blades, which increases the wind velocity through the blades. Support structures for the windmill are described, and also a method of using the windmill to store electricity to use later is shown. The windmill is more stable than conventional windmills. A method of using a windmill to generate electricity is also described.

摘要： The present invention relates to an installation tool for assembling a main rotor shaft unit and an assembly method thereof. The installation tool comprises a first element for supporting the generator end of the rotor shaft and a rotatable support plate is coupled to a second element of the installation tool via engaging coupling elements. The rotor shaft is rotated by a single crane unit via lifting elements mounted to the generator end, and then lifted out of the installation tool and placed on a floor. The bearing units are then mounted to the outer surface of the rotor shaft. The rotor shaft is afterwards lifted onto the installation tool so that the coupling element is brought into engagement and the rotor shaft is rotated on to the first element. This provides an installation tool that eliminates the need for two crane units to rotate the rotor shaft and reduces the amount of man-hours needed to assemble the rotor shaft unit by up to six hours. The installation tool also provides a stable tool for the workers since the center of gravity is located between the first element and the rotation point.
