Oldham's Coupling

Oldham’s Coupling


a device for connecting two shafts consisting of flanges attached to the ends of the shafts (half-couplings) and an intermediate disk which has on either side rectangular, mutually perpendicular transverse projections that fit into slots in the flanges. Such a coupling permits substantial transverse displacement of the shafts and some misalignment and axial displacement because of the clearances.
