Abstract
Rolling element bearings and particularly design features which reduce peak stresses acting on the bearing elements which affect bearing service life and rated load caring capacity. To reduce maximum stresses imposed by applied loads acting on the bearings, one or more of the bearing elements features an asymmetric configuration in which circumferential segments of the bearing element have increased flexibility. Such flexibility reduces maximum loads on the bearing and spreads out the load over a larger circumferential region. In addition to applied load components, nonuniform loads can act on rolling bearing elements at their lines of contact with the bearing raceways. In some embodiments of this invention segments of the bearing feature greater flexibility in order to adjust the load distribution acting on the rolling elements lines of contact.
