초록 ▼

A wind turbine assembly including a rotor body having mounted thereon a plurality of rotor blades. Each of the rotor blades may be joined at an inner extremity to a blade stem projection extending interiorly into the rotor body and secured to the rotor body by a torsional-spaced and axial-shock damping connection. The blade stem projection may also be secured within the rotor body in a manner allowing limited rotation of the blade stem projection relative to the rotor body, corresponding to a selective range of pitch of the associated rotor blade, with a system for rotating a blade stem projections of each of the rotor blades by corresponding degrees of rotation to provide a predetermined pitch of the rotor blades. Also disclosed are pitch-damping tower designs, and an integrated design wherein the tower is pitch- and yaw-damped.

A wind turbine assembly including a rotor body having mounted thereon a plurality of rotor blades, wherein each of the rotor blades is joined at an inner extremity thereof to a blade stem projection extending interiorly into the rotor body and secured therewithin to the rotor body by torsional- and axial-shock damping connection means, wherein each blade stem projection comprises a hollow cylindrical housing defining a central longitudinal axis therein, with a support member interiorly disposed in the housing at an intermediate position along its axis and fixedly secured to the housing, a shaft fixedly secured at one end thereof to the rotor body and coupled at its other end with the support member in a manner allowing limited axial and rotational movement of the housing relative to the rotor body, and a longitudinally outwardly biasing means between the support member and the rotor body, extending along the axis of the housing and outwardly abuttingly biased against the support member, whereby the biasing means provides torsional and axial shock damping to the rotor blade. A wind turbine assembly including a rotor body having mounted thereon a plurality of rotor blades, a nacelle to which the rotor body is coupled for rotation with respect to the nacelle, and a tower having an upper portion to which the nacelle is secured by coupling means, and a lower portion positionable on a support body, the tower upper portion including a cylindrical member at an upper end of the tower, wherein the coupling means comprise: a swivel mounting member comprising upper legs joined to the nacelle at opposite sides thereof by mechanical fastening means, and a lower stem telescopically positioned in the cylindrical member at the upper end of the tower and extending downwardly from the cylindrical member to a bottom stem portion, to permit rotation of the nacelle and rotor body relative to the tower; an oarlock connector joined to the bottom stem portion; a pitch biasing and damping member interconecting the nacelle and the oarlock connector, for pitch damping of the nacelle; and yaw biasing and damping means connecting the oarlock and upper portion of the tower, whereby the pitch damping/biasing member and the yaw biasing and damping means bias the rotor body and nacelle to a selected base position in relation to the tower, and dampen pitch and yaw displacements from said base position.
