GEISLINGER COMPOWIND® COUPLING
Installed between the rotor and the gearbox, the low speed shaft coupling is made from advanced fibre composites which enable the gearbox to be mounted rigidly onto the main frame. Additionally, the Compowind® Coupling facilitates highly integrated next-generation drivetrain architectures. Thanks to its low and almost linear restoring forces, virtually all occurring non-torque loads are effectively absorbed by the composite membranes.
Compowind® protects the gearbox and the whole drivetrain by significantly reducing non-torque loads. It allows the gearbox to be rigidly attached to the main frame for which reason drivetrain bending Eigenmodes are virtually eliminated and the dynamic behavior is improved beyond comparison. This is not only important under severe load conditions and after the occurrence of special events, but also helps to achieve tonality free wind turbines: The comparatively low stiffness and the good damping properties of the Geislinger Compowind® reduce the sound transfer from the gearbox to the rotor blades, while the attenuation of Eigenmodes helps to reduce sound propagation within the drivetrain in general. For this reason, the noise radiation from the rotor blades, the gearbox housing, the gearbox supports, and the tower is effectively reduced. This poses an additional customer value and a clear competitive advantage for onshore applications.
Compowind® is resistant to heat, frost, saltwater and oil and offers electrical insulation as an option. The use of advanced materials and our state-of-the-art manufacturing methods give wind turbine producers a competitive lead in the race for weight, enhancement of reliability and reduction of operational cost (OPEX). Every Compowind® is customized to each application.
