- Abstract
The static and dynamic load capacity in slewing rings depends on the contact geometry and the surface and subsurface hardening parameter. Usually, for the large diameter slewing rings, the raceway treatment is the induction hardening. The specific depth varies between 1 mm to 8 mm, depending upon the hardening technique and the material composition and quality. In this paper, the surface and subsurface stresses will be examined taking into account the link between the ball diameter and the material structure using a hardness compression algorithm. This reflects the contact limitations induced by the ball diameter and shows two possible regions for crack initiations in this rolling contact.
