Abstract
A flexible and rotatable coupling assembly for a feeder conveyor of a combine harvester, for example. The coupling assembly connects a first rotatable shaft to a second rotatable shaft. The coupling assembly includes a spherical bearing that is connectable to the first rotatable shaft for accommodating a radial or angular misalignment between the first and second rotatable shafts; and a flexible and rotatable coupler that is non-rotatably connectable to the first and second rotatable shafts for transferring rotation between the first and second rotatable shafts. The flexible and rotatable coupler is either directly or indirectly connected to the spherical bearing. The flexible and rotatable coupler has a flexible component for accommodating the radial or angular misalignment.
