ABSTRACT:
A hollow shaft composed of individual tube portions and provided with cams and end pieces, the individual tube portions preferably being interconnected by plastic expansion of the inner elements and elastic expansion of the outer elements. It is also possible to achieve a connection by shrinking the outer elements onto the inner ones by soldering or welding. Sleeves interconnecting the drive elements are designed to be integral with them and form part of the hollow shaft so that considerable weight savings are achieved by avoiding doubled regions where parts are slid onto each other. The design is particularly suitable for connecting parts with distinctly different elastic properties such as steel tubes and malleable cast iron drive elements.
