Abstract

A resilient shaft coupling. The parts of the coupling are supported by being radially braced against one another, but are movable relative to one another to a limited extent in the axial direction. One of the parts of the coupling contains an outer flange secured to a cylindrical jacket, the free end of which merges into an inwardly projecting flange. The other, inner part of the coupling contains a matching flange to which a bearing ring is rigidly secured and has an external collar coaxial with the axis of rotation and separated by a narrow annular gap from the inner wall of the jacket. The gap contains at least one bearing bushing which is adjacent the collar and jacket and radially braces parts against one another without preventing axial motion thereof. The parts are interconnected by at least one resilient annular member secured on one side to the matching flange and on the other side to the outer flange. Advantageously, the shaft coupling is constructed so as to contain two resilient annular members which are disposed in mirror image relationship relative to the central bearing ring and transmit equal parts of the total torque.
