    摘要： Methods and apparatus for assembling a wind turbine generator are provided. The wind turbine generator includes a core and a plurality of stator windings circumferentially spaced about a generator longitudinal axis, a rotor rotatable about the generator longitudinal axis wherein the rotor includes a plurality of magnetic elements coupled to a radially outer periphery of the rotor such that an airgap is defined between the stator windings and the magnetic elements and the plurality of magnetic elements including a radially inner periphery having a first diameter. The wind turbine generator also includes a bearing including a first member in rotatable engagement with a radially inner second member, the first member including a radially outer periphery, a diameter of the radially outer periphery of the first member being substantially equal to the first diameter, the rotor coupled to the stator through the bearing such that a substantially uniform airgap is maintained.

    摘要： A fluid transfer device and a method for conveying a fluid from a fluid transfer device to a rotating member are provided. The fluid transfer device includes a housing disposed around a first rotating member extending along an axis. The housing has a first plurality of apertures extending therethrough that communicate with the fluid source. The first rotating member has a second plurality of passageways extending from a first exterior surface of the first rotating member to a third passageway extending generally axially within the first rotating member. Further, at least a portion of the second plurality of passageways communicate with at least a portion of the first plurality of apertures, wherein the fluid flows through the first plurality of apertures and the second plurality of passageways to the third passageway in the first rotating member.

    摘要： A rotor, such as a rotor of an aircraft gas turbine engine, uses damper-ring devices for damping unwanted rotor vibrations. One device has inner and outer damper rings with the outer damper ring providing ring-rotor frictional damping only at large vibrational amplitudes and with the inner and outer damper rings providing inter-ring frictional damping at both small and large vibrational amplitudes. Other devices include a damper ring and a viscoelastic layer, a hollow damper ring containing particulate matter, and a damper ring in the form of a cable made of twisted single-wire strands.
