Wind Turbines Gearboxes Yaw Drives Gearbox Pitch Drives Speed Reducers

Wind energy is a growing industry, with technological advancements paving the way for more efficient and effective energy generation. Central to this development is the gear speed reducer, a crucial component in wind turbines. Our products, the EP700L4 yaw drive gearbox and pitch drive gearbox, offer superior performance in wind energy plants, contributing to sustainable and efficient energy production.

Superior Performance of Wind Turbines Gearboxes

Our EP700L4 yaw drive gearbox and pitch drive gearbox are central to the functioning of the wind turbines. They are responsible for the transmission of the rotor and the nacelle, housing the gearbox, the electrical generator, the yaw system, and the control system. With the yaw system, the nacelle can adjust its position according to the direction and force of the wind, ensuring maximum energy output.

Key Features of Wind Turbines Gearboxes

Our wind turbine gearboxes are designed to deliver high performance, durability and reliability. They have the following key features:

  • Output torque range: 1000-80000 N.m
  • Gear Ratios: i=300-2000
  • Support: slew support (with flange mounted)
  • Electric Brake: DC and AC type
  • Output shaft: splined or with integral pinion; output shafts supported by heavy duty capacity bearings
  • Applicable motors: IEC electric motors
