Voith’s D coupling

October 12, 2023 By Mike Santora Leave a Comment

voith-D-coupling-product-imageHighly 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.

Typical applications: engine test rigs

Advantages and benefits
D Couplings feature high torsional flexibility. This makes it possible to reproduce test cycles more precisely in supercritical operation and to achieve particularly precise test results.
A built-in spherical joint ensures balance between the engine and the power take-off. This test rig coupling is suited for engine speeds of up to 10 000 rpm. High-speed engines can be tested up to their maximum speed in most cases.

The coupling’s modular design makes it easy to integrate into a wide variety of engine test rigs. The connections can be adapted to almost all types of engines and dynos. This saves on adaptation expenses and allows you to build a better design with a shorter lever arm.

All connected components are relieved when moving through the resonance speed (engine start) and in other speed ranges. This extends the service life of all the test rig driveline components. Higher availability and lower total cost of ownership for your system increase your profits.
