The Geislinger Compowind is the first innovative coupling of its kind to enhance the reliability of wind turbines. Installed between the rotor and the gearbox, the Geislinger Compowind protects the drivetrain by a significant reduction of non-torque loads.
Deficient drivetrain reliability is still one of the main hurdles to get over to achieve competitive energy cost in particular with multi-megawatt wind turbines. Static and dynamic drivetrain distortions transmit bending moments from the rotor to the gearbox and its bearings. These non-torque loads cause excessive, uneven, and unpredictable loads to the drivetrain components and affect the reliability and uptime of wind turbines significantly.
IQPC’s drivetrain report states that gearbox failures are responsible for 39% of all downtime and, according to Romax Technology, in 80% of all cases a bearing failure is the root cause. Hence, the Geislinger Compowind has been developed, based on more than 20 years of experience developing maintenance-free and weight-saving couplings and shaft lines for demanding marine applications.
The advanced carbon-fibre, reinforced composite membrane coupling exactly meets the demands of wind applications: the weight-saving design doesn’t add unnecessary mass to the nacelle compared to standard coupling technologies and guarantees low (and almost linear) restoring forces. Furthermore, the Geislinger Compowind offers electrical insulation, as well as resistance to heat, frost, salt water, and oil.
Used on one of the most renowned offshore turbines, the maintenance-free Geislinger Compowind gives wind turbine producers a competitive lead in the race for weight and service life optimization. To meet the demands of different applications, every Geislinger product is tailor-made and, therefore, ideally suited to the application it is designed for. Minimal cost of ownership, outstanding service life, the highest quality standards and reliability are some of the most important features of Geislinger products.
