Abstract
Machine elements like rolling-element bearings offer a high potential for an increase in resource efficiency. Possibilities for optimization are weight reduction, an increase in performance, and integration of functions. The approach of Tailored Forming makes it possible to manufacture said components based on a new process chain. For this, joined semi-finished work pieces are utilized and formed, followed by the finishing process including heat treatment. To achieve tailored formed bearings, a deposition welding process on a mild steel with a hard facing with a higher strength steel is applied. The forging process improves the microstructural properties and allows achieving a near-net-shape fabrication to facilitate hard machining. Previous studies proved, that subsurface residual stresses can enhance the bearing fatigue life significantly. To improve the residual stress state of the surface deep rolling can be used. In order to calculate the bearing fatigue life, a three dimensional finite element model was developed. Based on the simulations output, the bearings fatigue life is determined based on the approach of Ioannides, Bergling and Gabelli. The method, which is based on a model of Lundberg and Palmgren, puts a material dependent stress fatigue limit (formula presented)u into relation with a fatigue stress criterion (formula presented)i. In our case, the Dang Van damage criterion is used. This numerical study deals with the enhancement for angular contact ball bearings by Tailored Forming and induced residual stresses.
