ABSTRACT:
A flexible coupling for rotatable shafts in the form of a metal bellows features a concentric sleeve which is fastened to one end of the coupling and which terminates in a plurality of fingers or keys projecting into, but without contact with, slots in the opposite end of the coupling. In normal use, the coupling transmits rotary motion from one shaft to the other shaft solely through the connecting bellows which provides the flexibility required for small amounts of misalignment and obliqueness of the coupled shafts. If the bellows broke, the concentric sleeve would function as the fail-safe coupling member to continue the transmission of the rotary motion.
