ABSTRACT:
An elastic coupling comprises an outer ring and a hub. A plurality of radially extending stacks of leaf springs are attached to the outer ring and engage axially extending recesses in the hub. Each leaf spring comprises a set of radially extending strips in axially adjacent coplanar arrangement, namely of one or more central strips and axially outer strips on both sides of the central strips and having smaller width than the central strips. Intermediate pieces are provided between the leaf springs along the inner surface of the outer ring. Each intermediate piece includes a radially outer surface. A radially extending slot disposed in each intermediate piece communicates with the radially outer surface thereby dividing a radially outer part of the intermediate piece into first and second portions on either side of the radially extending slot. An axially extending conical bore is disposed in each intermediate piece and communicates with the radially extending slot. An axial bolt having a conical shaft is disposed in the conical bore of each intermediate piece and engages the first coupling member so that upon tightening of the bolt the first and second portions of the intermediate piece are spread peripherally apart thereby clamping each stack of leaf springs between two adjacent intermediate pieces.
