A layout of a hollow shaft (1) which consists of individual pipe pieces (5) and is provided with drive elements, e.g. cams (2) or end pieces (3), is proposed which pipe pieces (5) are connected to one another preferably by means of plastic expansion of the respective inner partners and elastic expansion of the respective outer partners; a connection by means of shrinking the outer partners onto the inner partners, or by soldering or welding, is likewise possible. These connecting sleeves are designed as one piece with the drive elements, and themselves form a part of the hollow shaft so that considerable weight savings are possible by avoiding the duplication of parts pushed onto one another. The design is particularly suitable for the connection of parts with clearly different elastic properties, e.g. of steel pipes to drive elements consisting of malleable cast iron. ……
