Abstract
A flexible annular element made of elastomeric material (1) is provided for an elastic coupling device to connect two substantially coaxial shafts (11, 12). The device has a first flange (7) secured to the end of the first shaft (11), a second flange (8) secured to the end of the second shaft (12); and a clamp having supporting surfaces (9, 9a, 10, 10a) for clamping both sides of the annular edges (3, 4, 5, 6) of the annular element. The annular edges (3, 4, 5, 6) are provided, at least in the region of their contact with said bearing surfaces, with a lining having a slip coefficient greater than that of the elastomer of the flexible annular element.
