ABSTRACT:
A weld joint structure (12) is provided for a flexible coupling (10) having an inner hub (38), an outer cup (40), and an elastomeric ring (42) for torsional vibration protection of a drive train (14). The outer cup (40) defines an integral radially inwardly disposed tubular portion (64) having an internal seat (68), and an adapter member (70) of different ferrous material composition has an external seat (74) that is connected to the cup (40) by an annular weld joint (78). Preferably, the cup (40) abuts a shoulder (76) on the adapter member (70) where the weld joint is located, and a reverse bend transition portion (62) on the cup (40) functions with the tubular portion (64) to minimize bending loads on the weld joint.
