Gearboxes In Wind Turbines
Gearbox in wind turbines | Wind farms construction
In order to reach the correct rotational speed and generate power at the frequency needed by the grid you will need to use a gearbox between the main shaft (connected to the blades) and the secondary, “high speed” shaft linked to the rotor in the generator. The conversion ratio depend on the WTG model, but can be around 1:100. More Information

How are Falk Gearboxes Used in Wind Turbines?
Utility-scale wind turbines typically use three-stage gearboxes. The first stage is usually a planetary drive because of its high torque handling. The remaining two stages use helical gears. Falk gearbox specialists work with load cases—sensors on gearboxes measure over a period of time—because loads constantly change. More Information
Bearing and gearbox failures: Challenge to wind turbines
The gearbox in a wind turbine consists of several bearings that translate the wind energy from the spinning blades into electrical energy (see Figure 1). In the 21st Century, bearings are one of the most critical mechanical/tribological components used in a wide range of applications, including aerospace, automotive, energy, medical devices, sporting equipment and so on.

Gearboxes for Wind Turbines
The gearbox in a wind turbine does not "change gears". It normally has a single gear ratio between the rotation of the rotor and the generator. For a 600 or 750 kW machine, the gear ratio is typically approximately 1 to 50. The picture below shows a 1.5 MW gearbox for a wind turbine. More Information
