Abstract

The clamping connection for a pump shaft cantilever-mounted on a motor shaft has a cup-shaped pump shaft section (5.1) with a housing bore, and the portion of the cup-shaped shaft section embraced by the housing bore has a guide section and a clamping section. The clamping section is positioned on the end face of the cup-shaped shaft section and has at least two radially orientated longitudinal slots continuously splitting in the radial direction the circumferential wall of the clamping section between the housing bore and outer boundary.
