  • Publication number: 20110185832
    Abstract: A wind power plant transmission with at least one transmission stage which comprises at least a first and a second gearwheel, wherein a third gearwheel is provided which is connected axially to and is centered on the first or second gearwheels. At least the first, second and third gearwheels are encompassed by a transmission housing. Flange-mounted on the transmission housing is an auxiliary drive, where the torque of the auxiliary drive can be transmitted to the third gearwheel by a fourth gearwheel which is movable axially along, and can rotate with, a driveshaft which is driven by a motor. In an activated state of the auxiliary drive, the third gearwheel is in engagement with the fourth gearwheel. By omitting a front-mounted gearing and thereby reducing the number of individual parts, it is possible for a wind power plant transmission to be obtained in a more cost-effective and more compact manner.
