English term or phrase: radial foil bearing
The present invention provides ***a radial foil bearing ***for supporting a high-speed rotating shaft. The radial foil bearing comprises a top foil (1): a key (2) welded to a cut portion of the top foil; an inner bump coil (3) disposed outwards of the top foil, the inner bump being formed of a wider and higher bump and a narrower and lower bump alternately arranged; an outer bump foil (4) disposed outwards of the inner coil, the outer bump having a height lower the that of the narrower and lower bump of the inner bump foil; a bump sheet (5) for fixing the inner bump and the outer bump; and a bearing housing (6) disposed outwards of the bump sheet and having a key groove (7).
===
The hydrodynamic gas bearing is widely used in the high-speed rotation ap- plications, due to its low friction loss and unnecessity of liquid lubricant. In particular, it is used commonly in case of superspeed applications where the rolling bearing cannot be used for supporting and in case where a liquid lubricant cannot be easily used. The hydrodynamic gas bearing is categorized into a grooved bearing, a tilting pad bearing, and a ***foil bearing***.
===
The ***foil bearing*** for airplanes has been used mainly since 1970 in the air cooling machine (ACM), which is a core component for controlling the temperature and pressure inside the cabin in the environmental control system (ESC). This can be considered as a most suitable example of use. In this application, the ***foil bearing*** does not contaminate the interior of the cabin because it does not have any oil system. Also, it has enabled a stable operation for a long time, without scheduled maintenance, as compared with a ball bearing. When failed, advantageously it does not lead to the failure of other turbo-components. The ****foil bearing used in Boeing 747 **** has been being operated more than 100,000 hours, without any repair.

Внешне - похож на "foil journal bearing"

"The rotating journal (shaft) of a foil air bearing acts as an air pump creating a thin layer of high pressure air that is captured between the journal and top foil. The bump foil acts as a spring to tailor the compliance of the bearing and minimize air leakage thus improving load capacity."
