Abstract

A shaft coupling assembly having a first and a second internal fluid chamber system, each containing therein a fluid medium which is placed under pressure when torque is transmitted through the coupling assembly, each of the fluid chamber systems including a plurality of chambers and a plurality of channels which converge from a common point placing the channels in flow communication with each other and which interconnect the plurality of chambers of each of the systems. The channels of the first and the second systems are axially offset relative to each other and each of the systems is designed to create a throttling effect offering resistance to flow of the fluid medium within each of the systems. The coupling assembly enables compensation for axial, radial, angular and/or torsional shaft offset and, additionally, makes it possible to damp the vibrations in an axial, radial, angular and torsional direction and to adjust the stiffness of the coupling assembly.
