Abstract

A compliant, acoustically insulating, torsionally elastic shaft coupling includes a shaft part and a driver part formed by support plates. At least one cage is defined by the support plates which house at least one rubber element of corresponding shape. To achieve an especially compliant torsionally spring characteristic line, the rubber element is formed with uniformly spaced cavities having a cross-section larger than that of hollow ducts centrally crossing a series of these cavities and extending at least essentially over the entire height of the rubber element.
