  • Resilient-membrane coupling element for use in a torque transmission path, and method of manufacture
    Patent number: 5364309
    Abstract: A coupling element between tubular shaft sections comprises two mutually adjacent membrane walls, each having radially outer and inner circumferences. The membrane walls are mutually connected at their radially outer circumferences. The radially inner circumferences of the membrane walls are in axial alignment with radially inner circumferences of respective shaft sections, and the membrane walls are connected at their radially inner circumferences to the tubular shaft sections. The radially outer circumferences of the membrane walls are elastically decreasable, and the radially inner circumferences of the membrane walls are elastically expandable in response to axial forces applied to the membrane walls in axially opposite directions.
