ABSTRACT:
A rotationally elastic coupling with two half-couplings can be twisted relative to one another, these half-couplings being connected with one another so as to transmit forces by means of a sprung intermediate link and by means of a movement-converting intermediate link which converts a rotation into a translational movement or, vice versa, a translational movement into a rotation. At least one sheet metal support is provided which is in contact at a radially outward position with one of the sprung intermediate links which in turn is supported rotationally solidly and frictionally at a radially inward position with one of the two half-couplings. The sheet metal support is subjected to forces directly or by means of a coupling element of the movement converting intermediate link, in particular an eccentric or a crank, this movement converting intermediate link being rotationally and rotationally solidly connected to the other half-coupling. Using such a coupling, practically linear and soft spring characteristics can be produced for high torques over twist angle ranges of far beyond 30.degree..
