Finite element analysis of a non-symmetric ring rolling process of a taper roller bearing outer race and verification

초록

In this study, we conduct computer simulation of non-symmetric ring rolling of a taper roller bearing outer race. A rigid-plastic finite element method is employed. An idling disk is devised to reduce the intrinsic oscillatory motion during non-symmetric ring rolling as well as to reduce the friction between the disk and the workpiece and its applicability and effect are shown by both experiments and simulations. The formation of both under-filling defect on the outer face and tilting defect of the outer face of the taper roller bearing outer race is revealed by the ring rolling simulation.
