How are gears & gearboxes used in wind turbines?

May 18, 2011· Conventional utility-scale wind turbines often use three- stage gearboxes. The first stage is often a planetary drive because that design handles high torque best. The later two stages use helical gears. To give an idea of the torque coming from a rotor, consider a 1.5-MW turbine working at its rated output. 1.5 MW = 2,011 hp.
