  • Integrative transmission chain of hybrid-drive wind turbine and a gearbox used by the transmission chain
    Patent number: 10215260
    Abstract: An integrative transmission chain of hybrid-drive wind turbine and a gearbox used by the transmission chain, comprising a front housing body, a rear housing body, a main shaft and a planet carrier, and further comprising: an inner ring gear on the main shaft, N intermediate gears (N?3), N planet gear shafts provided with a first stage planet gear and a second stage planet gear, an output shaft, and a sun gear; wherein the inner ring gear, the intermediate gear and the first stage planet gear form a first stage fixed shaft transmission pair, and the second stage planet gear and the sun gear form a second stage fixed shaft transmission pair; and wherein an upwind end of the output shaft is axially rotatably disposed on the planet carrier and a downwind end of the output shaft protrudes outside the rear housing body; the downwind end which protrudes outside is connected to an upwind end of the rotor of the generator so as to drive the rotor of the generator in rotation, and a downwind end of the rotor of the gen
