Wind energy system with a coupling between the planetary gear and generator to compensating for axial, radial and angular displacement

摘要

The wind power plant (1) has rotor (3) and integrated medium-speed electric generator (4). A planetary transmission (2) is provided for converting slow rotary motion of rotor into rapid rotary motion to operate generator. The transmission is provided with transmission input shaft (5) connected indirectly to rotor, and transmission output shaft connected to generator indirectly via generator shaft (6). A coupling mechanism is arranged between generator and transmission to compensate axial, radial and angular misalignment between transmission and generator shaft.
