Abstract

A connection system for connecting an impeller to a shaft is provided. The impeller has a shaft-side hub extension with a central hole. The connection system has a connector body which is inserted into the hole. The connector body has a threaded portion carrying a thread which screws onto a corresponding threaded portion of the shaft such that the connection system provides a rotationally fixed connection between the impeller and the shaft. The connection system further has a plurality of circumferentially distributed elongate threaded members which join the connector body to the hub extension such that the connector body is axially fixed relative to the impeller. The connection system further has plurality of circumferentially distributed torque transfer members which extend between the connector body and the hub extension to transmit a majority of the torque between the shaft and the impeller. Corresponding impeller and turbocharger are also provided.
