centrifugal
coupling
Hydraulic centrifugal couplings are fluid couplings based on the Föttinger principle. They
consist of 2 hinged hemispheres with blades separated by a tight gap.
The applied torque is transmitted by the inertial force of the streaming fluid. This fluid
circulates within a closed circuit, between the pump wheel (primary side) [12] on the driv-
ing shaft (motor shaft) and the turbine wheel (secondary side) [9] on the driven shaft
(gear unit input shaft).
The following figure shows the structure of a drive with hydraulic centrifugal coupling:
