Abstract
A power transmission system for increasing the rotational speed from a rotor of a wind turbine comprises a main shaft configured to be driven by the rotor, a support structure, and a gearbox. The support structure includes at least one bearing supporting the main shaft for rotation about the main axis, with no other degrees of freedom between the main shaft and support structure. The gearbox includes a gearbox housing rigidly coupled to the support structure and a gearbox input member coupled to the main shaft. The gearbox housing supports the gearbox input member for rotation about the main axis without any other degrees of freedom, and the gearbox input member is coupled to the main shaft with translational degrees of freedom in all directions and rotational degrees of freedom about axes perpendicular to the main axis.
