Kurzfassung

The roller burnishing and deep rolling of drill holes or other profiles is a well established process for achieving a very high surface quality and for significantly enhancing the fatigue strength. With the development of the rolling-in process for manufacturing composite workpieces such as e. g. composite shafts and camshafts the possible fields of application of the rolling process can be extended by an interesting aspect. For rolling-in, specially adapted tools were used with a higher rolling oversize to join by expanding an inner component inside an outer part, both parts optimised to meet special requirements regarding their material and shape. Additionally it is much easier to manufacture the components before fixing them on the tube. In the context of the presented investigations different correlations between the joining parameters and their effects on the torque stability of the joining connection are pointed out.
