摘要： A tapered polygon coupling for an impeller and shaft. The shaft 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 shaft. A fastener is provided for securing the impeller to the shaft. 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 shaft and the impeller. Additionally, the impeller may include the tapered bore having a polygonal cross-section, and the shaft may include the tapered polygon plug configured to be placed in the bore of the impeller.
