Abstract:
1. An asymmetric torque limiter to interconnect a wind turbine with a generator shaft, comprising: an input housing and an output hub; an over running mechanism interposed between said input housing and output hub; a first torque limiting mechanism positioned in series interconnection with said over running mechanism between said input housing and output hub; a second torque limiting mechanism positioned in parallel interconnection with said over running mechanism between said input housing and output hub; and wherein said first torque limiting mechanism comprises a friction plate assembly, and wherein said over running mechanism is maintained about an inner circumference of said friction plate assembly and interfaces with said output hub, and further comprising an end plate sealed between said input housing and output hub, a pressure plate, and a spring assembly interposed between said end plate and pressure plate, said spring assembly forcing said pressure plate into contacting engagement with said friction plate assembly.
