ABSTRACT:
A rotary-elastic oscillation-damping shaft coupling includes a fluid damping arrangement. Transmission of torque from the primary part to the secondary part is accomplished by a disk-like coupling part which extends approximately perpendicular to the axis of rotation. The coupling part is provided on one side with axially-extending projections and recesses arranged in a ring. The lateral surfaces of the projections and recesses are inclined toward one another in a circumferential direction. The coupling part engages similar projections and recesses of the disk-like secondary part, or a coupling disk connected to the latter. Sets of spring elements, preferably cup springs, are arranged laterally on the coupling part. The coupling is filled with damping oil, which is pressed through throttle devices provided under the action of the axially-shiftable coupling disk, from one side of the disk to the other.
