  • Wind turbine power transmission system
    Patent number: 9771924
    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.

  • NACELLE CONSTRUCTION FOR A WIND TURBINE
    Publication number: 20170045038
    Abstract: A heli-hoist pad that is incorporated into a wind turbine nacelle in a manner that is optimized for helicopter approach and positioning of the heli-hoist pad, such as by being located within a recess in an upper surface of the wind turbine nacelle. Heat exchangers may also be positioned within the free flow of wind outside of a nacelle in manners that provide for serviceability while also allowing for optimal positioning of a heli-hoist pad.

  • Nacelle construction for a wind turbine
    Patent number: 9512823
    Abstract: A heli-hoist pad (18) that is incorporated into a wind turbine nacelle (12) in a manner that is optimized for helicopter approach and positioning of the heli-hoist pad (18), such as by being located within a recess (20) in an upper surface (28) of the wind turbine nacelle (12). Heat exchangers (50) may also be positioned within the free flow of wind outside of a nacelle (12) in manners that provide for serviceability while also allowing for optimal positioning of a heli-hoist pad (18).
