Offshore wind turbines represent the most hostile operating environment for any industrial gearbox: salt spray, condensation cycling, high humidity, corrosion from marine atmosphere, inaccessibility for maintenance (weather windows of only 60–100 days per year at many...

The yaw drive on a wind turbine rotates the entire nacelle — gearbox, generator, rotor, and all — around the vertical tower axis to face the wind. A 3 MW turbine nacelle assembly weighs 60–90 tonnes and must rotate smoothly through 360° over the course of a day as...

The pitch drive on a wind turbine blade is one of the most safety-critical planetary gearbox applications in existence. It must rotate each blade precisely around its longitudinal axis — from 0° (full power) to 90° (full feather, no power) — in response to control...

The main gearbox in a wind turbine is the single most mechanically demanding planetary drive in commercial production — a 5 MW offshore turbine rotor turns at 8–12 rpm and must deliver that torque to a generator spinning at 1 200–1 800 rpm, giving an overall ratio of...
