A wind turbine comprising:
- a tower having a top end and a bottom end;
- a first eccentric mechanism connected to a turbine rotor, the turbine rotor being at the top end of the tower;
- a second eccentric mechanism connected to an electric generator, the electric generator being at the bottom end of the tower;
- a plurality of tensile links connecting the first and second eccentric mechanisms;
- wherein the first eccentric mechanism is a cam-follower mechanism and the cam-follower mechanism has a cam shaft with at least one cam profile, a plurality of cam lobes driven by the turbine rotor, and a plurality of cam followers driven by the plurality of cam lobes;
- wherein each tensile link of the plurality of tensile links has a first end connected to a cam follower of the plurality of cam followers;
- wherein each cam lobe has a cam lobe head and each cam lobe head of the cam shaft is separated by a phase angle offset of 360/(n*m) degrees measured about an axis running parallel to a length of the cam shaft, wherein n is equal to the number of tensile links of the plurality of links and m is equal to the number of cam lobe heads per cam profile;
- wherein the second eccentric mechanism is a swashplate mechanism and the swashplate mechanism has an output shaft and a plate, the output shaft is connected to the electric generator, and the plate is connected to the plurality of tensile links at connection locations;
- wherein the plate has the connection locations disposed at equal distances along a perimeter on the plate and the perimeter is disposed around the output shaft.
