Abstract: A wind turbine device, in which the rotor of the wind turbine is connected to a rotor shaft, and in which a torque is transmitted from the rotor to a power machine, and in which the torque is transmitted between the rotor and power machine via a harmonic gear.
Abstract: A harmonic gear device (10) in which a spindle (28) and a gear rim (48) are rotatable relative to each other on a common centre axis (32), and in which a gearwheel (42), which is engaged with the gear rim (411), is rotatably connected to the spindle (28) around a first eccentric axis (36), and in which a balancing gearwheel (58), which is engaged with the gear rim (48) or a balancing gear rim, is rotatable around a second eccentric axis (40).
