VERFAHREN UND VORRICHTUNG ZUM FÜGEN VON GEBAUTEN HOHLWELLEN

摘要

The method of joining cams to tubular camshafts (18) involves placing the cams lobes on the tube exterior and subjecting individual section of the tube to internal fluid pressure (64) to deform them plastically outwardly to engage and retain the cam lobes. The cams and tube are jigged (90) and the individual tube sections are expanded sequentially to engage the lobes. Claims include a machine for making camshafts using the method.
