ABSTRACT:
A flexible coupling for connecting a rotary drive to a rotary load where the respective axes are subject to angular or parallel misalignment. An input hub on the drive shaft is connected to an intermediate member through a tripodic connection assembly and the intermediate member is in turn connected to an output hub on the load shaft through another tripodic connection assembly. Each tripodic connection assembly comprises three flexible resilient elements in the form of strips generally arranged to form an equiangular triangle. The strips are each connected by rigid connections to one of the hubs at one of their ends and to the intermediate member at the other of their ends. The respective connections for corresponding ends of the strips are at three symmetrically spaced locations around a circumscribing circle. The strips are adapted to flex intermediate their ends during rotation of the drive and load to accommodate angular misalignment and/or parallel misalignment between the respective axes of the shafts.
