Title:
WIND POWER PLANT TRANSMISSION AND AUXILIARY DRIVE FOR A WIND POWER PLANT TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2010/023055
Kind Code:
A3
Abstract:
The invention relates to a wind power plant transmission with at least one transmission stage which comprises at least a first and a second gearwheel. Furthermore, a third gearwheel is provided which is connected axially to and is centred on the first or second gearwheel. At least the first, second and third gearwheels are encompassed by a transmission housing. Flange-mounted on the transmission housing is an auxiliary drive, the torque of which can be transmitted to the third gearwheel via 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. As a result of the omission according to the invention of a frount-mounted gearing and a resulting reduction in the number of individual parts, it is possible for a wind power plant transmission to be realized in a more cost-effective and more compact manner.
