Abstract (en)
[origin: EP1440745A1] The built-up camshaft (11) consists of a tubular shaft (12) and several cams (14), each with a through aperture (15), pushed onto the shaft and fixed to it at a spacing from each other. The tubular shaft has heat-deformed sunken side joints (22) between the cams. These joints may have projections which exceed the external diameter of the shaft to enlarge the cross section of the through apertures
