APO RESEARCH · REPORT
Wind Turbine Generator Gearboxes
Wind turbine generator gearboxes use geared stages to adapt rotor speed and torque to the generator's operating requirements.

Product & engineering
Understand the product.
Planetary and parallel-shaft stages transmit loads through gears and bearings. Housing stiffness, alignment and lubrication influence contact conditions.
Wind and grid events create changing loads rather than a steady operating point. Maintenance access and condition monitoring affect the cost of service.
What turns activity into demand
Wind turbine gearboxes transfer variable rotor loads to the generator; load distribution and lubrication affect service life.
The commercial boundary
Separate gearbox assemblies from individual gears, bearings and direct-drive turbine systems.
