Abstract
A flexible shaft coupling is of the kind comprising two annular assemblies which transmit torque between two rigid coupling parts which are arranged concentrically one within the other. The annular assemblies are concentric and have a space between them, and groups of radially directed filament loops or turns, which are embedded in an elastomeric mass, extend around members of the assemblies to interconnect the assemblies. Parts of the loops or turns between the members are supported on elastic cushions, which are formed by parts of the elastomeric masses, and are displaceable inwards into gaps between the members and within the elastomeric masses. The members of one assembly are attached to one coupling part and the members of the other assembly are attached to the other coupling parts. In order to ensure that in service, the filament loops or turns and the elastomeric masses in which they are embedded remain stressed in tension, in spite of fluctuations in the torque transmitted, the groups of filament loops or turns in their masses of elastomeric material are mounted so that they can pivot relative to the rigid coupling parts about axes which are parallel to the common axis of the coupling parts.
