Boundary layer improvement of plate springs or undulating springs

A process for producing plate springs or undulating springs wherein surface regions which are subjected to tensile stresses when the spring is under load are provided with an internal compressive stress in the boundary layer, wherein said surface regions are rollingly compressed by a ball or roller...

Beschreibung
Zusammenfassung:	A process for producing plate springs or undulating springs wherein surface regions which are subjected to tensile stresses when the spring is under load are provided with an internal compressive stress in the boundary layer, wherein said surface regions are rollingly compressed by a ball or roller or subjected to tensile stress and compressed by shot peening.
