This flexible-disk coupling contains at least one disk attached at its outside to one of the two rotary parts connected therewith and is splined adjacent its inside periphery to the other of said parts. The splines let the disk expand naturally under centrifugal stress, independently of said other part. They have preferably straight radical profiles, so that the increased expansion of the disk avoids backlash. The couplings may be used in pairs, as common-place, or also singly. The flexible disks are subjected to various stresses, of which the stress set up by centrifugal inertia is a major component. It is customary to rigidly weld the disks at their inner portion to one of the two parts connected by the coupling. The invention departs from this custom. It lets the disks expand naturally without being tied to the expansion of said one part. As this decreases the stress on the disks it enables them to carry increased load.

A flexible-disk coupling for connecting two rotary parts, containing a flexible disk attached adjacent its outside periphery to one of said parts and adjacent its inside periphery to the other of said parts, the latter connection being with splines having straight radial sides intersecting, when extended, the axis of said other part, to allow the internal splines to expand more than the mating external splines while maintaining contact between the mating splines without introducing backlash.
