HOLLOW SHAFT WITH DRIVE MEMBERS

Drive elements, particularly cams (2), are affixed on a hollow shaft (1) in such a manner that specific sections of the same (11) are expanded, i.e. plastically deformed. In this case, the opposite regions of the cams are elastically deformed. If these regions include brittle, e.g. hardened, materia...

Zusammenfassung:	Drive elements, particularly cams (2), are affixed on a hollow shaft (1) in such a manner that specific sections of the same (11) are expanded, i.e. plastically deformed. In this case, the opposite regions of the cams are elastically deformed. If these regions include brittle, e.g. hardened, material, there is a risk of crack formation. It is thus proposed that the cams be split into a first section (21), consisting of a material with a low expansion capability, and into a second section (22), consisting of a material with a high expansion capability, and that only the latter be subjected to deformation by the expansion process.
