An active bearing at least for vibration reduction is described, comprising a) an interface () to be fitted to a load (); b) at least one support element () in an operative connection with the interface () and a support unit (); c) at least one linear actuator () supported indirectly or directly on the support unit (); d) a gear unit () for the path transmission of an actuating path change originating from the linear actuator (), said gear unit being in an operative connection with the at least one linear reactor (); e) at least one decoupling unit (), which serves for the decoupling of the static load transfer and for transmitting the dynamic load transfer; wherein the at least one linear actuator (), the gear unit () and the at least one decoupling unit () are disposed serially.

Active bearing

A device for transmitting or decoupling mechanical vibrations between a first component and a second component with at least one of the first and the second components being free to vibrate in the at least one direction including: a planar coupling element, coupling the first and second components together, having a planar top surface and a planar bottom surface, and having a variably adjustable stiffness extending in the at least one direction; the planar coupling element, having planar dimensions with the planar coupling element being dimensionally stable along the planar dimensions and being elastic in a direction perpendicular to the planar surfaces; the first and second components are rotatable relative to each other about an axis extending in the direction perpendicular to the planar surfaces and in which at least one of the components is free to vibrate for adjusting the stiffness.
