Abstract

A turbocharger is provided having a connector (3) for connecting an impeller (1) to a shaft (2). The impeller has a shaft side hub extension (H) with a central recess. The impeller is formed of a material having a greater coefficient of thermal expansion than the material of the shaft. The connector is inserted into the recess to frictionally connect an outwardly facing surface (14) of the connector with a radially inner surface of the hub extension. The connector has a threaded portion (11) carrying a thread which screws onto a corresponding threaded portion (7) of the shaft such that the connector provides a rotationally fixed connection between the impeller and the shaft. The connector is formed of a material having a coefficient of thermal expansion which is greater than the coefficient of thermal expansion of the material of the shaft.
