Method for joining components with hollow shafts, preferably for the manufacture of camshafts and camshaft made according to the same.

摘要

Method for joining components with hollow shafts, preferably for producing camshafts, manufactured in a first process step the components, especially cam rings, with its contour conditioned by function, using for this purpose a material which can harden having after curing, aside from its elastic deformability, also a permissible plastic deformability reduced, inserting these components properly function in a forming tool internal high pressure (IHU) together with the hollow to be deformed tree, and in a second process step, joining the components with hollow frictional and positive fit by a hydroforming process by the effect of the internal pressure, characterized in that the material can harden presents after curing a permissible residual expansion of tree = 0, 5%.
