Abstract: A bearing sealing arrangement for rotating machines uses a radially-acting labyrinth seal (2) to minimize bearing lubricant leakage and an axially-acting screw-type gasket (3) to return what fluid escapes through the labyrinth seal to the bearing (10). In embodiments, the labyrinth seal uses rings (4) with plastic wear surfaces formed about internal metal bands, the plastic forming corresponding profiles on the ends (27,28) of the bands so that the profiles interlock when overlapped to form the rings. The screw-type gasket preferably includes rotor-mounted helical fillets (22) formed in a section (21) that is retained in a seat (20) on the rotor. The section in embodiments is retained by inserting a ring-shaped key (23) into the section, thereby forcing the section into undercuts of the seat. The arrangement is particularly useful in wind machines, such as wind-turbines.

The claws (2, 3) can elastically pivot about the bridge (5) when the terminal expansions (11) are squeezed together or forced apart, allowing insertion of and securing the magnet assembly, respectively.

Abstract: The invention relates to a wind power current generator comprising a bearing, a tubular stator that carries a race of the bearing, a tubular rotor coaxial with the tubular stator that can rotate in relation to the stator, a hub connected to the rotor, and at least two blades radially extending away from the hub. According to the invention, the stator and the rotor are formed with substantially tubular cross sections and are concentric to one another. The opposing surfaces of the rotor and stator carry permanent magnets and windings. The stator and rotor extend beyond either side of the magnets and the windings in order to accommodate an antifriction bearing on at least one side. The tubular nature of the rotor and stator allows easy passage of workers within the generator for maintenance thereof and of the blades. Additionally, the tubular nature facilitates air flow through the structure and out the blades, cooling equipment within the structure and aiding de-icing of the blades.
