Abstract
A flexible drive coupling for transmitting rotational forces between respective flanges of a driving shaft and a driven shaft. The flexible drive coupling has, in a substantially planar circular configuration, a number of wedges. The wedges have respective end faces facing the adjacent wedges and connected thereto by flexible elements. Alternate wedges attach respectively to the flanges of the driving and driven shafts. The flexible elements consist of a link between two end plates. The mating faces of the link and the end plates are curved so that they co-operate one with the other. An elastomeric filler occupies the space between the curved surfaces of the end plates and the links permitting each end plate to pivot with respect to the link by deforming the elastomeric filler. The end faces of the wedges and, the corresponding faces of the end plates of the flexible elements which face them, have co-operating tabs and recesses to prevent relative radial and axial movement. On attaching the flexible drive coupling to the driving and driven shafts, the wedges can be forced radially inward and so secured that the flexible elements are pre-loaded in radial compression.
