Abstract
An electrically insulating overload coupling for a wind turbine generator includes a gear-side or generator-side hub having an axially oriented ring flange. A pipe made of an electrically insulating material and having an axial section with an annular circumferential sliding surface rests directly on a corresponding sliding surface of the ring flange, so that the pipe is rotatable in a torque-dependent manner in relation to the ring flange.
