Fluid-lubricated foil bearings, and foils for such bearings

摘要

In a fluid-lubricated foil bearing, the foils (16) are retained in place on one of the bearing members (14) by having an end portion (17) of the foil, which end portion is rolled into a part-cylindrical shape, received in a slot (15) of part-circular cross-section formed in the bearing member (14). The slot (15) is sufficiently deep that its mouth is narrower than its widest part, so that the end portion (17) of the foil (16) cannot escape from the slot (15).
