ABSTRACT:
A drive train for a wind turbine is provided. The wind turbine includes a rotor hub and one or more blades. The drive train includes a first stage carrier connected to the rotor hub. The first stage carrier includes one or more first stage planet gears that interact with a fixed first stage ring gear and a rotating first stage sun gear. A second stage planet carrier includes one or more second stage planet gears. The second stage planet carrier is rigidly connected to the first stage sun gear. The second stage planet gears interact with a rotating second stage ring gear and a non-rotating second stage sun gear. A generator includes a generator rotor and a generator stator, and the generator rotor is fixedly connected to the second stage ring gear so that both the generator rotor and the second stage ring gear rotate together.
