Abstract
An extra-resilient shaft coupling. Two rigid parts are interconnected by a resilient intermediate member which transmits torque. The intermediate member includes two external metal ring members which are in the form of one or more peripheral parts and are interconnected by an elastomeric material, preferably vulcanized in situ. To avoid over-stressing the elastomeric material at the regions adjacent to the metal parts, the ring members, near the outer peripheral surface of the rubber element, are provided with an axially projecting annular shoulder which abuts an edge region of the rubber element. The inner peripheral edge of the ring members has an approximately V cross-section, the point of the V being rounded and the outer side surface being recessed relative to the outer surface of the ring member to thus form a peripheral recess for receiving a lip formed on the rubber element. In the case of an intermediate member which is divided into segments, the abutting edges of the metal segments are formed in the same member as the inner peripheral edge of the ring members.
