Fluid coupling

Fluid couplings for smooth starting of the machine - e. g. for conveyors

The fluid couplings of KTR Systems are hydraulic couplings for hydrodynamic power transmission according to the Foettinger Principle.

Function of fluid coupling:

The operating principle of the fluid coupling is originally based on the hydrodynamic torque converter patented by Hermann Foettinger (1877 - 1945) (Foettinger Principle). Here the inertia forces are transmitted by a flowing fluid (e. g. oil), driving and driven side being mechanically separated from each other.

With this operating principle the mechanically driven pump wheel accelerates the fluid in the work space via radially arranged internal blades. The rotational energy of the circulating fluid absorbed by the blades of the turbine wheel accelerates this process and the resulting mechanical power is dissipated on the driven side.
