Line of wind-turbine couplings withstand high misalignment while remaining torsionally stiff. Designed with composite disk packs (flex elements) at both ends of a center spacer, the packs provide high strength and flexibility.

The center spacers can be machined out of steel, composite glass fiber, or 6061- T6 aluminum engineered to withstand in excess of 100,000-Nm torque.

The flex elements electrically insulate the turbine’s generator from the gearbox, eliminating stray electrical current that can leak across the coupling and damage bearings. The coupling transfers lower reaction loads to the generator bearings. The composite material withstands temperature extremes from –40 to 70°C, moisture, and chemicals native to wind-turbine nacelles.
