Coupling technology

Timken imagined a way to transmit torque between the gearbox and generator while protecting attached components from overload and stray currents. Next-generation Lovejoy couplings, bolted to an AeroTorque WindTC torque control, are now available for 2MW+ turbines. These couplings integrate directly with the generator hub, include an anti-flail feature, and use a composite fiberglass spacer for weight and cost efficiencies. An AeroTorque-enabled coupling provides advantages such as reducing peak torque by up to 40% and reducing torque oscillations up to 70% to extend gearbox life. Together, Lovejoy and AeroTorque are part of a strong, technical solution for making reliable gearbox-to-generator connections.
