hydrodynamic coupling

In general, this new high-performance transmission clearly illustrated the enormous capability of hydrodynamic couplings.

Hydrodynamic coupling may refer to:

By 1929, the first Voith hydrodynamic couplings based on the Föttinger Principle were in use at the Herdecke pumped-storage hydropower station.

Together, they expanded the company's role in industrial drive technologies, and in 1929 Voith produced the first hydrodynamic coupling and transmission using the Föttinger Principle.

The torque transmitting capacity of any hydrodynamic coupling can be described by the expression , where is the mass density of the fluid, is the impeller speed, and is the impeller diameter.

Because this layer is so thin there is extensive hydrodynamic coupling between the bilayer and the substrate, resulting in a lower diffusion coefficient in supported bilayers than for free bilayers of the same composition.

The hydrodynamic couplings that allow over 100% slipping between input and output shafts are used in difficult ice conditions to increase propeller torque and protect the main engines from large torque variations resulting from propeller blades hitting the ice.

Vehicles having a hydrodynamic coupling, hydrodynamic torque multiplier or electric motor as part of the power transmission system may also have a maximum continuous tractive effort rating, which is the highest tractive force that can be produced for a short period of time without causing component harm.
