Highly-Elastic Coupling Solution for Water Turbines

The sector of hydropower always uses special water turbines, often in the form of constant-pressure turbines and reaction turbines, for energy conversion. In this process, the kinetic energy of the water is converted to rotation energy via the turbine, effecting a rotation of the turbine shaft which, in turn, actuates a generator to produce power. For the functionally critical connection between the turbine and the generator shaft, customers all around the world for example rely on the unique RINGFEDER^® TNB coupling series with radially installed buffers. The elastic, non-switching shaft couplings of this series are characterised by excellent damping properties and maximum torque transmission densities and allow for an extraordinary ease of servicing. In addition to an individual adaptation complying with application-specific requirements, the couplings can also be equipped with an effective overload protection function, if necessary, in order to reliably prevent potential damage of the generator.
