Abstract
A tapered polygon coupling for an impeller and pinion. The pinion has a tapered bore having a polygonal cross-section. The impeller includes a corresponding tapered polygon plug configured to be placed in the bore of the pinion. A fastener is provided for securing the impeller to the pinion. The fastener passes through a passage in the plug of the impeller. The plug of the impeller is split so that when the fastener is inserted into the passage the plug expands to contact the bore and create an interference fit between the pinion and the impeller.
