Patent ID: 7935020

Claim:
A drive train for a wind turbine, said wind turbine comprising a low speed shaft connected to blades of the wind turbine and a higher speed shaft connected to a generator, said drive train comprising: a bearing substantially supporting the weight of at least said low speed shaft; a compound planetary gear stage; said compound planetary gear stage connected to said low speed shaft and said higher speed shaft, said compound planetary gear stage comprising, a rotating carrier; a non-rotating ring gear attached to at least one of a main bearings mounting plate and a main frame of the wind turbine; a plurality of planetary gears; and a rotating sun gear connected to said higher speed shaft; and one or more elastic mounts attached directly to the non-rotating ring gear and at least one of the main bearings mounting plate and the main frame, the one or more elastic mounts decoupling at least a portion of, at least one of, axial and lateral forces impressed upon the wind turbine, the axial and lateral forces created by wind impinging on the blades of the wind turbine.
