ABSTRACT:
An Oldham coupling for connecting two parallel structural parts such as shafts is disclosed wherein an intermediate ring is freely movable between the hubs of the two structural parts intended for connection. The ring carries on its flat sides two lands located at 90.degree. relative to each other and the lands engage corresponding grooves in the hubs. The lands are convex at their friction surfaces and the load bearing walls of the grooves are correspondingly concave to receive the lands. An Oldham coupling of this type is particularly suitable as both a guiding and a rotation inhibiting mechanism for the revolving displacement body of a rotating piston machine of the displacer type.
