Abstract

A resilient shaft coupling, especially for Diesel engine drives, essentially comprises two rigid coupling parts such as a hub on the drive side of the shaft coupling and a flange ring on the end of the drive shaft opposite to the drive side, whereby the hub and the flange ring are connected in an elastic rotating manner via a series of identical elastic annular connecting links. Radial supports for the elastic annular connecting links are provided at one of the rigid coupling parts in order to avoid improperly restraint masses that cause imbalance of the shaft due to centrifugal forces. In order to improve the angular movability of the resilient shaft coupling, the radial supports are provided with angular movability. This is achieved by a metallic ring membrane which provides angular movability between two axially neighboring annular connecting links, whereby the ring membrane is clamped between the connecting rims of the annular connecting links. The ring membrane is equipped with a boring, that tightly embraces the hub, and is thereby supported in a radially rigid, but axially and in a circumferential direction flexible fashion that also allows angular motion. The support at the hub is achieved by a sliding sleeve. Each metallic ring membrane may consist of one or more segments, successively arranged in its circumferential direction.
