Abstract
A journal foil bearing includes a bearing retainer having one slot configured to receive a top foil leading edge tab and another slot configured to receive a top foil trailing edge tab. A backup support structure, integral to the bearing retainer, extends between and is at least partially defined by the slots. The retainer is configured so that, during operation, the trailing edge tab further contacts, at an increased contact pressure, the support structure at a position close to the friction force, thereby minimizing top foil bending stress and improving bearing strength.
