Winged elastomeric coupling with minimized separation forces between elastomer and clamp ring

A coupling for transmitting torque between two shafts approximately aligned on a shaft axis, the coupling having a center axis approximately aligned with the shaft axis, the coupling comprising:

• arcuate coupling segments with ends extending generally parallel to the coupling center axis and arcuate portions extending between the ends, the arcuate coupling segments being arranged in a ring with adjacent segments being arranged end to end to form the coupling, each coupling portion comprising:
• a center element formed from an elastomer material having axially opposite sides;
• and
• a first clamp ring extending from one axial side of the center element and a second clamp ring extending from the axial opposite side of the center element, each clamp ring including an attachment portion adapted to be operatively attached to a shaft, the attachment portion extending axially from each of the axially opposite sides of the center element;
• wherein the elastomer material extends axially and circumferentially from the center element axially opposite sides adjacent to each end of the arcuate coupling segment.
