Zero-Max Wind Turbine Couplings are engineered to withstand high misalignment while remaining torsionally stiff

Zero-Max Wind Turbine Couplings are available as an upgrade replacement for existing wind turbines and for OEM applications. Zero-Max couplings are engineered to withstand high misalignment while remaining torsionally stiff. They are designed with composite disk packs at both ends of a center spacer. The composite disk packs (flex elements) are designed to allow a surplus of parallel and axial misalignment while remaining torsionally stiff through all harmonic ranges of the wind turbine’s oscillating load.

Zero-Max’s center spacers can be machined out of steel, composite glass fiber or 6061-T6 aluminum. Through the use of Finite Element Analysis (FEA), these center spacers can be engineered to withstand 100,000 Nm of torque.

The flex elements are engineered to electrically insulate the turbine’s generator from the gearbox. The coupling is designed to protect the generator by transferring lower reaction loads to the generator bearings. The coupling’s composite material is engineered to withstand environmental elements, including temperature extremes from -40 to +70° C, and moisture and chemicals native to the nacelles of wind turbines.
