Abstract
A transmission assembly for coupling a forerunning gearbox stage to a generator of a wind turbine is provided, the transmission assembly including an intermediate speed shaft supported by an intermediate speed shaft bearing arrangement and including an intermediate speed shaft gear, a high-speed shaft supported by a high-speed shaft bearing arrangement and including a high-speed shaft gear, and a gear mesh formed by an engagement of the intermediate speed shaft gear and the high-speed shaft gear, wherein the gear mesh is configured to transfer a torque between the intermediate speed shaft and the high-speed shaft.
Claims13
A transmission assembly for coupling a forerunning gearbox stage to a generator of a wind turbine, the transmission assembly being divided into an input side and an output side, the transmission assembly comprising:
- an intermediate speed shaft supported by an intermediate speed shaft bearing arrangement and configured to rotate about an intermediate speed rotational axis, wherein the intermediate speed shaft comprises an intermediate speed shaft gear,
- a high-speed shaft supported by a high-speed shaft bearing arrangement and configured to rotate about a high-speed rotational axis, wherein the high-speed shaft comprises a high-speed shaft gear and is configured to rotate faster than the intermediate speed shaft, wherein the intermediate speed rotational axis and the high-speed rotational axis are arranged in parallel;
- and
- a gear mesh formed by an engagement of the intermediate speed shaft gear and the high-speed shaft gear, wherein a separation plane arranged at the gear mesh perpendicular to the intermediate speed rotational axis and the high-speed rotational axis separates the two sides of the transmission assembly,
- wherein both the intermediate speed shaft and the high-speed shaft each comprise a coupling end;
- wherein the coupling end of the intermediate speed shaft is arranged at the input side and is configured to be coupled to an output of the forerunning gearbox stage,
- wherein the coupling end of the high-speed shaft is arranged at the output side and is configured to be coupled to the generator,
- wherein the high-speed shaft gear and/or the intermediate speed shaft gear are supported by the respective bearing arrangement in a cantilever manner;
- wherein one of the high-speed shaft bearing arrangement or the intermediate shaft bearing arrangement is arranged on the input side and the other one is arranged on the output side.
