Wind Turbine Pitch Drive Planetary Gearbox: Blade Angle Control

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...

Wind Turbine Main Gearbox Planetary Drive: Design Overview

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...
