Abstract
An asymmetric torque limiting coupling system for use on wind turbines, in which a forward torque limiting clutch and a reverse torque limiting clutch are provided in paired relation, with the reverse torque limiting clutch having a characteristic slip torque that is significantly less than that of the forward torque limiting clutch. In a specific embodiment disclosed, an asymmetric torque limiter interconnects a wind turbine with a generator shaft. The coupling includes an input housing and an output hub, with an overrunning mechanism interposed between the two. A first torque limiting mechanism is provided in series interconnection with the overrunning mechanism between the input housing and hub, while a second torque limiting mechanism is provided in parallel interconnection with the overrunning mechanism between the input housing and output hub.
