Abstrakt: 1.SPS hardening of the parts of alloy-steel shafts under the hub that were heat-treated to high strength categories makes it possible to utilize the advantages of these steels that their strength provides. The endurance limit of SPS-hardened specimens with press-fitted mating parts was 2.6 times higher than of non-hardened specimens.2.SPS is a very efficient means of increasing the fatigue resistance of the part of the shaft under the hub, even when the keyway is milled after strain-hardening.3.Fretting and fatigue damage on the parts of shafts under the hub in press-fitted keyway joints may occur on both sides of the keyway at its end and on the side opposite to the keyway.
