Couplings in drive lines are of particular importance because they transmit power between the input and output side, and compensate for inevitably occurring misalignments of the units. Like other machinery elements, couplings need to be serviced at regular intervals. Only if the coupling is optimally tailored to the requirements of the operating conditions and subject to regular maintenance, can it contribute to ensuring the operating reliability and efficiency of a machine or plant.  

The demands made on the components in combined heat and power plants (CHP) are increasing. They have to be efficient, long-lasting and, in case of an emergency, must at least fulfill the safety requirements set forth by the Medium Voltage Guideline. Thomas Marterer, Product Manager at RINGFEDER POWER TRANSMISSION, explains how operators of CHPs can find the correct coupling for their plant: The coupling should withstand high temperatures and be neither torsionally too stiff nor too soft.

"The challenge to develop a highly flexible coupling is to design a coupling which has a particularly soft characteristic curve", explains Norbert Telaar, Head of Strategic Product Management at RINGFEDER POWER TRANSMISSION, the main task of his team. In the end they developed an innovation in coupling design.
