Finite Element Analysis on Convexity for Tapered Roller with Arc-Line Modification Profile
Taking double-row tapered roller bearings of a rail passenger coach as research object, the analysis on convexity for tapered roller bearings has been carried out. The comparison of contact stresses at different convexity values with the ANSYS has been done, the optimal range of convexity value under a certain load has been obtained. The results show that the reasonably design of convexity can avoid or reduce the border contact stress concentration occurred between rollers and inner, outer ring raceways under certain condition. But the approximate theoretic convexity and the results obtained by Finite element analysis have a certain margin of error.
