The present invention relates to a product of the area of clean and renewable energy. Its object is an unprecedented arrangement of conical blades of elongate "shell' type, for moving vertical-axis wind turbines, enabling more concentration and force to drive and move the vertical shaft. The blades are interconnected by means of a horizontal support circular bar, forming a sort of flywheel that strengthens the structure of the turbine, making it more resistant to strong winds, besides distributing equally, over the blades, the horizontal forces of the wind acting on them, resulting in stability to the torque. The blades are long, designed intentionally in this way to capture the Wind forces at a distance from the rotation shaft to increase the torque on its shaft. Since the resulting of the wind forces concentrates at a point away from the rotation shaft, a high torque is produced with multiplying lever effect on the central shaft. The turbine may further have upper and/or lower diagonal bars or cables, forming an arrangement similar to a latticework for supporting the weight or the vertical forces that act on the blades, centralizing them on the vertical rotation shaft. The turbine will be fixed to the movable part of a special shaft bearing with gas suspension that will have a compartment filled with a gas that has lift property to keep the turbine suspended, absorbing all or almost all its weight, facilitating rotation and reducing friction, noise and, as a result, increasing efficiency. |
