Patent number: 8827561Abstract: A wind turbine includes a tower (8), a nacelle (3) being connected to the tower (8), and a rotor (2) having a rotor hub (6) and a number of rotor blades (7) extending radially outwards from the rotor hub (6). The nacelle (3) includes a hollow shaft (10) and the rotor hub (6) includes a support member (11) which is connected to the hollow shaft (10) by two tapered roller bearings (14, 15) so as to be rotatable about an axis of rotation (5). The tapered roller bearings (14, 15) each have a bearing width (w) which is defined in a direction parallel to the axis of rotation (5). The tapered roller bearings (14, 15) are arranged at a distance (d) from one another which is not greater than the bearing width (w) of the tapered roller bearings (14, 15).Type: GrantFiled: December 8, 2010Date of Patent: September 9, 2014Assignee: Lagerwey Wind B.V.Inventors: Hendrik Lambertus Lagerweij, Albertus Waaijenberg, Aart van de Pol, André Pubanz

Patent number: 8384233Abstract: Direct driven wind turbine includes a tower, a nacelle, a rotor blade, a radial flux generator with a stator and a rotor, wherein the lamination package of the generator is essential for the transfer of the torque in axial direction. By introducing this additional function to the lamination package, the generator can be provided without additional torque transferring housing. Preferably, the lamination package obtains this additional function by pressing together the laminations between the front plate and end plate by tensile bolts. This gives sufficient strength to transport the torque in axial direction through the laminations to the mounting points of the generator. Preferably, the laminations include cooling fins. Due to these measures the cooling of the generator improves and active cooling may become superfluous or the power can be increased. The housing of the laminations is an expensive, heavy and labor intensive part which is no longer required due to the invention.Type: GrantFiled: July 14, 2010Date of Patent: February 26, 2013Assignee: Lagerwey Wind B.V.Inventors: Hendrik Lambertus Lagerweij, Andre Heinz Pubanz, Aart Van Der Pol, Albert Waaijenberg
