Abstract
The strength behaviour of adhesively shrink-bonded shaft-hub assemblies under torsional loading has been investigated using steel specimens (C45 and 42 Cr Mo 4) with a shaft diameter of 80 mm. Static and fatigue tests have been carried out to determine the influence of specimen design, stress ratio (mean stress sensitivity) and loading spectrum on strength behaviour of shrink-bonded assemblies. Besides the experimental investigtions the complete stress state in the adhesive layer of the different specimens is analysed using finite element method. On the basis of the stress analytical studies and the experimental results a method for design and optimization of shrink-bonded assemblies is developed. The theoretical evaluation and experimental results coincide quite well in all cases investigated thus showing that the procedure is suitable for practical application.
