A flexible coupling for connecting two shafts comprises two hubs (10, 12) with an intermediate member (14) therebetween and two membranes (15), all in axial alignment. Hub (10) is secured to one membrane (15) by fasteners (24) and hub (12) is similarly secured to the other membrane (15). The two membranes are coupled to the intermediate member (14) by further fasteners (24). The fasteners (24) extend through holes in the membranes with clearance. The fasteners (24) are located within peripheral slots (16) in the hubs (10, 12) so that the hubs do not have to be provided with precisely located and dimensioned holes for the fasteners. Upon axial compressive loading, washers (26) flanking the membranes will become embedded in the hubs and may flow to take up the clearance spaces. If steel washers are used, the clearance spaced are instead filled by swelling of the fasteners (24) when the fasteners are staked to retain the compression. The fasteners (24) may be semi-tubular rivets, nuts and bolts, or threaded rivets with nuts. |
