Numerical Results of a Quasi-Static Analysis on Hybrid Ball Bearings (original) (raw)

A comparative numerical quasi-static analysis has been made between an angular steel ball bearing and an angular hybrid ball bearing, having the same external and internal geometry (7007C series). Though a quasi-static program offers only a solution independent of time regarding the contact forces, it is useful to appreciate the load distribution and the fatigue life for a rolling bearing. To reduce the maximum load values and to increase the bearing life the results indicate the need of geometry optimisation for the inner race/ ball contacts in the hybrid rolling bearing. KEYWORDS: hybrid rolling bearings, quasi-static analysis 1. INTRODUCTION The rolling bearings' application at ultra-high speeds is limited, because in such conditions the outer ring race is extra-charged due to the centrifugal forces acting upon the rolling elements. Lightweight balls must be used for decreasing the centrifugal forces effects. There are two solutions to obtain lighter balls: (i) the decreasing...
