Abstract
Combining shrunk fit with adhesive bonding in shaft hub joints significantly increases static and fatigue strength. The paper reports on investigations of adhesively bonded shrunk shaft-hub Joints under torsion and combined static or alternating torsion and rotating bending. Tests with torsion and combined static torsion and rotating bending mainly show failure of the adhesive layer, while alternating torsion and rotating bending predominantly causes fretting fatigue failures. The high-cycle fatigue strength is significantly decreased. Based on experimental results a normalized 3-D-fatigue diagram is developed. Parameters for normalization are the torsional strength and the endurance limits of alternating torsion and rotating bending. These parameters represent the various influences on the strength of the joint. The normalized fatigue diagram is the base of a design method called "Bezugsspannungsmethode".
