Abstract
In torsional vibration dampers and torsionally elastic coupling which comse torque-transmitting spring elements, which are clamped between spacers by an external clamping ring, which is elastically expanded for the installation of the spacers and spring elements. For a quick and efficient assembling of the dampers or couplings, the spacers alone are initially inserted into the clamping ring and are then subjected to radially outwardly directed pressure until the clamping ring has been expanded beyond the extent required to clamp the spring elements, which are subsequently inserted between the spacers, whereafter the spacers are relieved from pressure. This method can be carried out with the aid of a cylindrical assembling head, which is provided at its periphery with at least one radially movable pressure-applying member, which cooperates with at least one hydraulic cushion, which is adapted to be pressurized.
