  • Integrated medium-speed geared drive train
    Patent number: 7935020
    Abstract: A drive train for a wind turbine is provided. The wind turbine comprises a low speed shaft connected to blades of the wind turbine and a higher speed shaft connected to a generator. The drive train also includes a bearing that substantially supports the weight of at least the low speed shaft. A compound planetary gear stage is connected to the low speed shaft and the higher speed shaft, and includes a rotating carrier, a non-rotating ring gear, a plurality of planetary gears, and a rotating sun gear. The sun gear is connected to the higher speed shaft.

  • Wind turbine generators having wind assisted cooling systems and cooling methods
    Patent number: 7427814
    Abstract: A wind generator includes: a nacelle; a hub carried by the nacelle and including at least a pair of wind turbine blades; and an electricity producing generator including a stator and a rotor carried by the nacelle. The rotor is connected to the hub and rotatable in response to wind acting on the blades to rotate the rotor relative to the stator to generate electricity. A cooling system is carried by the nacelle and includes at least one ambient air inlet port opening through a surface of the nacelle downstream of the hub and blades, and a duct for flowing air from the inlet port in a generally upstream direction toward the hub and in cooling relation to the stator.
