A resilient shaft coupling in which a rigid primary and a rigid secondary coupling member are connected together by at least one resilient annular assembly of a multi-part construction that is composed of a number of ring segments that are identical and run circumferentially in close succession. Each segment is composed of axially outer metallic segment plates and an inner rubber body that has a trapezoidal cross-sectional shape with a radially outwardly increasing width in an axial plane. In order to obtain higher thermal stressability of the shaft coupling, at least one window is provided in the rubber body of each segment. The ends of the window end in the vicinity of the radial end faces of the segment. Openings are also provided in the two segment plates of each segment and are congruent with the window in the rubber body.

A resilient shaft coupling for interconnecting a rigid coupling member on a driving side and a rigid coupling member on a driven side particularly for a diesel engine drive mechanism with which considerably greater thermal stressability especially with elastomeric bodies having larger dimensions must be provided to avoid unacceptably high heating therein, said coupling having an axial direction and having the improvement in combination therewith comprising: at least one resilient annular assembly that provides said interconnection between said rigid coupling members and that includes two ring halves that are disposed in axially abutting relationship as mirror images of one another, with each of said ring halves being divided into segments that are successively arranged in a circumferential direction, with each of said segments having a location of radial end faces thereof and comprising, when viewed in the axial direction of said coupling, an outer segment plate, an inner segment plate, and therebetween an elastomeric body that is vulcanized to said inner and outer segment plates, with said elastomeric body having a trapezoidal cross-sectional shape and including an entire axial width thereof which increases in a radially outer direction; the segments of one of said ring halves are offset relative to the segments of the other of said ring halves by one half of a segment division, with said inner segment plates of abutting ring half segments being clamped together; said elastomeric body of each of said segments is provided with at least one window, with each such window extending in a circumferential direction, as well as over the entire axial width of said elastomeric body, and having two end walls and therebetween two essentially concentric curved walls, with said end walls of said window terminating in the location of radial end faces of said segment; each of said inner and outer segment plates of each of said segments is provided with at least one opening, which is congruent with said at least one window of said elastomeric body of that segment, said window and said opening collectively forming an axial passage through which cooling air flows to alleviate problems of greater thermal stressability.
