What is the job of a coupling in a wind-turbine drivetrain?

Flexible couplings in wind turbines are used on the high-speed (the output) shaft of the gearbox to drive the generator. The task is made more difficult because the coupling is working in a nacelle where everything − gearbox and generator mostly − moves around, a bit thanks to the high vibration environment. While the gearbox and generator ...
