LINK-TYPE ROTARY COUPLING ABSTRACT A link-type rotary coupling for use in a coupling for transmitting torque between rotatable drive and driven means while accommodating angular misalignment between their rotational axes, including a plurality of links interconnect- ing the drive and driven elements. The improvement resides in that the link comprises an axially stiff body adapted to accept both tensile and compressive loads applied tangentially between the drive and driven elements. A first elastomeric bearing is provided for connecting a first end of the body to the drive element to permit the body to pivot about at least one axis while undergoing elastic compression during application of tension to the body. A second elastomeric bearing is also provided for connecting a second end of the body to the driven element to permit pivotal movement of the body about a second axis parallel to the previous said one axis. At least a selected one of the first and second elastomeric bearings also permit pivotal movemnt of the body about a third axis orthgonal to either the first or second axis. The selected elastomeric bearing is adapted to undergo elastic shearing during the pivotal motion about both the orthogonal axes and to undergo elastic compression when the body is subjected to tension while rotating about misaligned axes to accommodate the link motion necessary to effect a substantially constant velocity connection between the rotatable members.
