Plymouth, Minn.-based Zero-Max Inc., a manufacturer of power transmission components, has introduced composite disc couplings for the wind turbine industry.
The couplings are designed with composite disc packs at both ends of a center spacer. These patented designed disc packs provide the true strength and calculable flexibility of the coupling. The composite disc packs (flex elements) allow a surplus of parallel and axial misalignment, while remaining torsionally stiff through all harmonic ranges of the wind turbine's oscillating load.
Depending on application, the 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, these center spacers can be engineered to withstand in excess of 70,000 Newton meters of torque, depending on the material selected.
