Abstract

The disclosure concerns a torsionally elastic coupling comprised of a central hub and an outer ring around the hub and spaced therefrom wherein the ring may relatively shift with respect to the hub. A series of leaf-spring assemblies are arrayed around the hub and the leaf-springs thereof project from the inner hub to the outer ring. A respective groove in the outer ring receives at least the longer ones of the leaf-springs of each assembly. Reinforcements are positioned in these grooves for being engaged by the leaf-springs. The leaf-springs of each assembly are of varying length. For holding the leaf-spring assemblies to the hub, there are wedge-shaped intermediate pieces between adjacent leaf-spring assemblies. Alternate wedge-shaped intermediate pieces are fastened to the hub and the other alternate ones are integrally formed with the hub.
