摘要： In the production of an assembled camshaft slid-on elements, such as control cams, bearing rings, gear wheels or bevel gears, are placed on an axially extending shaft tube. The slid-on elements are secured in place by expanding the shaft tube in the region of the elements by applying internal pressure. In producing the camshaft, a high strength material is used for the slid-on elements and an inferior strength material for the shaft. In the expanding step, an axially extending portion of the shaft tube is plastically deformed and the slid-on element is predominately elastically deformed. After expansion, the outer zone of the slid-on elements are elongated in the tangential direction in the range of 1%.
