Abstract
A resilient shaft coupling having damping by liquid displacement. Resilient elements, which extend radially of the axis of rotation, are disposed between the driving and driven members of the coupling, the resilient elements being connected to the outer driven coupling member (the outer ring), and having their free ends received in axial recesses in the generated surface of the inner driving member of the coupling. Each resilient element extends between liquid-filled chambers bounded by filling elements, the liquid responding to a relative movement between the driving and driven members of the coupling by being displaced from the chamber into the adjacent chamber bounded by the resilient elements. The spring elements on their end faces have journal pins which engage, with the interposition of bearing sleeves, in corresponding bores in the outer driven coupling member, one or both of the journal pins being directly connected to the driven coupling member to rotate positively therewith.
