摘要

A rotor fastening arrangement, particularly for connecting a drive shaft and a rotor hub of a centrifugal pump assembly, having a fitting surface and at least one contact surface at the drive-shaft end. Respective ends of the drive-shaft (3) and the rotor hub (1a) are each provided with an internally threaded central hole. A fitting surface and at least one contact surface also are formed on the rotor hub (1a). An intermediate shaft (2) is provided between drive shaft (3) and rotor hub (1a) in order to connect the rotor hub and drive shaft. A fitting surface and at least one contact surface are formed respectively at both ends of the intermediate shaft (2) for alignment; at least one connecting member is provided for connecting the intermediate shaft (2) to the drive shaft (3) and the rotor hub (1a), and a seal is arranged on the intermediate shaft.
