<p>A flexible coupling including flexible diaphragm means has at least one and more commonly a plurality of diaphragms (51,53) having a particular profile (61,63). The profile has first and second contoured sections. The first contoured section (98) has a radially-inwardly decreasing thickness and extends to near the center (100) of the diaphragm (90) and the second section (102) extends therefrom and has a radially-inwardly increasing thickness such that the bending moment developed by axial deflections is small near the thinnest section or the center (100) of the diaphragm (90), and the stress levels are minimized throughout the diaphragm (90). The diaphragm profile as described tolerates greater axial deflection and bending before the fatigue and endurance limits of the diaphragm material are reached than has heretofore been the case.</p> |
