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 contacts the support structure at a position close to the friction force, thereby minimizing top foil bending stress and improving bearing strength.

Abstract translation: 一种日志箔轴承包括一个轴承保持器，该轴承保持器具有一个槽，该槽被配置为接纳顶部箔片前缘突出部，另一个狭槽被配置成接收顶部箔片后缘突出部。 与轴承保持架成一体的后备支撑结构在槽之间延伸并至少部分地由狭槽限定。 保持器构造成使得在操作期间，后缘突片在接近摩擦力的位置处接触支撑结构，从而最小化顶部箔弯曲应力并改善轴承强度。
