Abstract

See full text

A wind turbine power generating system includes a wind turbine connected to a speed increasing gearbox having an output shaft. An electrical generator having an input shaft is also provided. An asymmetrical coupling interconnects the input and output shafts. The coupling includes a first torque limiting clutch in series connection with a one-way clutch between the input and output shafts. A second torque limiting clutch is provided in parallel connection with the one-way clutch between the input and output shafts. The first and second torque limiting clutches have different characteristic slip torques. The interconnection of the clutches, and the implementation of the one-way clutch, provides for effective operation of the first and second torque limiting clutches in opposite rotational directions of the input and output shafts. The second torque limiting clutch has a characteristic slip torque that is a fraction of the first torque limiting clutch, the second torque limiting clutch providing protection against reverse impulse loads.
