Hydrodanamic tapered roller bearings and gas turbine engine systems involving such bearings

摘要

Tapered roller bearings (200) and gas turbine engine systems involving such bearings are provided. In this regard, a representative bearing cage (238) for a gas turbine engine includes: an outer cage rim (240) and an inner cage rim (242); the outer cage rim having a rounded edge (254) at a location of contact (255) between the outer cage rim (240) and a roller (250).
