Highly flexible couplings D Couplings

Download Catalog

Highly flexible D Couplings are the standard for engine test rigs for testing 1 to 3-cylinder internal combustion engines. D couplings feature a high torsional flexibility and high torque capacity. Development test rigs, continuous-running test rigs, and end-of-line test rigs operate safely and reliably with this coupling at speeds of up to 10,000 rpm.

D Couplings shift a system's critical resonance frequencies below idle speed. In addition, the couplings dampen undesirable alternating torques. This increases the service life of all the test rig drive components. Your test rig operates with a high level of availability.

The D Coupling's modular design enables very flexible integration into a wide variety of engine test rigs. We adapt the length of the coupling, connections, and torsional rigidity to your test rig.

  • D Couplings feature high torsional flexibility.

  • A built-in spherical joint ensures balance between the engine and the power take-off.

  • The coupling's modular design makes it easy to integrate into a wide variety of engine test rigs

  • All connected components are relieved when moving through the resonance speed (engine start) and in other speed ranges.
