    • 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.
    • 风力涡轮发电系统包括连接到具有输出轴的增速变速箱的风力涡轮机。 还提供具有输入轴的发电机。 不对称耦合将输入和输出轴互连。 联轴器包括与输入轴和输出轴之间的单向离合器串联连接的第一扭矩限制离合器。 第二扭矩限制离合器设置成与输入轴和输出轴之间的单向离合器并联连接。 第一和第二扭矩限制离合器具有不同的特征滑移扭矩。 离合器的互连和单向离合器的实现提供了第一和第二扭矩限制离合器在输入和输出轴的相反旋转方向上的有效操作。 第二扭矩限制离合器具有作为第一扭矩限制离合器的一部分的特性滑移扭矩,第二扭矩限制离合器提供防止反向冲击负载的保护。
