Composite Disc Coupling

Patented, Proven Disc Coupling Design

Zero-Max’s flexible composite disc wind turbines feature a unique, patented composite disc design that can withstand harsh environmental conditions. Capable of withstanding up to 200,000 Nm of torque, these overload safety couplings allow a surplus of parallel and axial misalignment while remaining torsionally rigid through all harmonic ranges of the wind turbine’s oscillating load.

Our flexible, dielectric composite disc couplings provide electrical isolation to nullify current leaks from the generator into the gearbox, preventing damage to bearings and teeth. Intelligent design minimizes reaction loads while providing the required torsional stiffness value to suit drivetrain requirements.

The composite materials used in our wind turbine disc couplings are designed and tested to withstand a wide range of environmental conditions, including moisture, chemicals, and extreme temperatures from -57° to 121°C (-71° to 250°F). Center spacers are manufactured from composite, steel, or aluminum.

The couplings themselves are fully tested and refined to handle loads well beyond the needs of the application. They are proven to perform with no maintenance for 20-plus years through testing under conditions simulating a 20-year torque load spectrum of continuous operation.

Used on conjunction with our wind turbine torque limiters, our composite disc couplings provide the highest level of overall protection for modern wind turbine drivetrain requirements.
