Product Portfolio
  • Gearboxes

  • Pioneered and perfected by Winergy
    Winergy, the global market leader, produced its first wind-turbine gearbox in 1981, and since then has continuously worked on technical and quality-related concepts. Setting the standard in the industry for combined helical and planetary stages as well as super-finishing of gears, Winergy has delivered over 70,000 gearboxes to its satisfied customers.

    Gearboxes for a wide power range
    As the central component of the drive system, the gearbox converts the low speed of the rotor shaft into a high revolution that drives the generator. Winergy offers both standard and customer-specific engineered products in the power range from 600 kilowatts to 6.5 megawatts - always optimized for the given requirements.

      • HybridDrive

      • The wind turbine power pack
        To bring the energy generation costs down to a minimum, drive components for wind turbines must be designed to deliver the highest possible efficiency. To meet all customer requirements, Winergy has added a new concept to its product portfolio - The HybridDrive.

        Compact and efficient
        The direct linkage of the two-speed gear and the permanent-magnet generator shortens the drive train by up to 50%. Despite its compact dimensions, the HybridDrive is extremely efficient. In fact, with an efficiency of >96,5% (measured @ rated power) for gearbox and generator, it has the best efficiency of any existing technology.

        Benefits of the Winergy HybridDrive for wind turbines:
        • Compact dimensions: Gear unit and generator in a single product
        • Best possible efficiency for onshore and offshore use
        • Flexible, for use in any nacelle configuration
        • Highly maintenance and service-friendly thanks to modular design
        • Low dependence on rare earth materials
        • Choose between conventional roller bearings and innovative slide bearings.
      • Multi Duored Gearbox

      • With its very high power density (Nm/kg) the Multi Duored technology is convincing as a result of its compact design and the reduced costs per kW. In addition to the more compact design, the two output shafts are certainly worth noting. These are coupled to two generators connected in parallel instead of to just one single generator.

        When designing this unit, special emphasis was placed on ensuring that service can be performed as efficiently and simply as possible. In the Multi Duored gearbox, the small parts in the area of the bearings, gearing and casting parts are almost all identical. As far as the size and weight of these components is concerned, it was ensured that the capacity limits of the load cranes in the nacelle are not exceeded and also that these parts can be manufactured worldwide. The compact design of the individual parts increases the stiffness of the gearbox as a whole. This is the reason that the gearbox runs smoothly and precisely even during fast power transients. The gearbox can be rotated through 360° around the longitudinal axis to allow all of the modules in the nacelle to be accessed for service. This flexibility means that all of the components are accessible and the gearbox can be completely overhauled locally. Removal and logistical costs are eliminated.

        Advantages of the Multi Duored gearbox:
        • High power density in a compact and light design
        • Great serviceability
        • Maintenance and service are possible without having to remove the unit from the nacelle
        • Two generators for variable power output
        • Scalable up to 12 MW
    • Couplings

    • Making reliable connections
      A reliable connection between gearbox and generator is an important factor in successful wind energy production. The coupling does not only transmits the torque, it also protects the attached components against overload and travelling leakage currents. In the process of delivering thousands of high-quality wind couplings, Winergy has gained a lot of experience and expertise, which are continuously being incorporated in the development of new products. Winergy's maintenance and wear-free products connect our customers' drive trains over the entire lifetime of the wind turbine, making the investment calculation easy for each wind turbine OEM and developer.

      Advantages of Winergy couplings
      • Maintenance-free, wear-resistant, no lubrication required
      • Nearly unlimited service life
      • Comprehensively tested in our testing center
      • Excellent power-to-weight ratio and structure-borne noise insulation
      • Permissible angular misalignment up to 3°
      • Coupling components can be dismounted radially, so connected machines stay in place
      • Available in an electrically insulating version with overload protection
        • Added value through systems expertise

            • Winergy - a pioneer in the wind power industry

            • In 1981 Winergy started as one of the first suppliers the industrial production of gearboxes especially designed for the wind industry. At that point Winergy still belonged to Flender - the renowned gearbox manufacturer with nearly 100 years of experience. The product portfolio was expanded to include couplings even prior to the foundation of Winergy AG in 2001.

              Market leader with 30 years of experience
              Thirty years of experience has resulted in a gearbox track record of more than 70,000 installed gearboxes - a number that is growing every year. Every second wind turbine worldwide is equipped with at least one Winergy component. This experience has helped us to become what we are today: the global market leader for drive train components.
            • Winergy globalized presence

            • Moving together with our customers into new markets was a logical step for Winergy, enabling us to make high-quality products available under local conditions.

              After Winergy AG was founded 2001 in Germany, Winergy Drive Systems Corporation was established in the same year in Elgin, IL, USA.
