Abstract
The fastening arrangement (26) for an impeller (22) on a shaft (14), in particular for an impeller (22) of a turbocharger on a turbocharger shaft (14), comprises a bush (34), which can be screwed onto a shaft journal (20) of the shaft (14), and a shaft-side hub extension (30) of the impeller (22) having a central recess (32), into which the bush (34) can be inserted in a frictional manner. The hub extension (30), at least in the region of its shaft-side end, is designed approximately in the form of a hollow cylinder. The fastening arrangement (26) also comprises a press sleeve (36) which can be frictionally connected radially on the outside to the hub extension (30).
