Technical Paper: API-all-steel coupling with optimised performance

Marc Egelwisse

In the Arpex all-steel multi-disk coupling the Flender GmbH, a 100 %-held Siemens subsidiary, is marketing a coupling that has proved itself over many years. Marc Egelwisse, product manager for Arpex couplings, and his team have further developed this series with a focus on three aspects:

  • increase in the specific power,
  • optimisation of the areas of application and
  • reduction of complexity of the type series.

The results show it was worth it:

  • 70 to 100 % higher torque,
  • 40 % greater angular misalignment,
  • 10 % higher maximum speed and
  • 14 instead of the 42 design variants existing hitherto.

“Because of the high torque capacity and the optimised speed and bore capacity of the new N-Arpex we are confident that we are offering what is at present the world’s best-performing coupling”, says Egelwisse.
