It is the task of the gear unit to step up the low speed of the rotor shaft via several gear stages to the high speed of the output shaft driving the rotor of the generator via the coupling. The gear unit mainly comprises four subassemblies: Castings (housing, planet carrier, torque reaction arms); geared parts (gears, pinion shafts); rolling bearings, and small parts.

To step up the low rotor shaft speed to the required high speed level, different gear stages are combined in a wind turbine gear unit. The present standard is a combination of one planetary gear stage (low-speed gear stage) and two helical gear stages (high-speed gear stages) or two planetary gear stages and one helical gear stage.

Winergy developed this concept of today's standard gear units and introduced it onto the market in 1989; and in the then following years it was adapted by the competitors.

Winergy is market and quality leader both on the entire market for wind turbine gear units and in the fast growing multi-megawatt class. At present, our range features four gear unit types of different sizes as series products covering a power rating range from 600 to 5,000 kW.
