Abstract
A radial foil bearing includes a carrier foil formed from a corrugated foil, a first curved segment formed from a first top foil and a second curved segment formed from a second top foil. The second curved segment is arranged successively on the carrier foil after the first curved segment to form a tubular carrier comprising two curved segments when the carrier foil is rolled. In an embodiment, the carrier foil has a first end and a second end, and, after the carrier foil is rolled to form the tubular carrier, the tubular carrier has a circumferentially closed shape and the first end faces the second end.
Claims19
A radial foil bearing having at least one top foil and at least one corrugated foil, wherein:
- the top foil and the corrugated foil are constructed one on top of the other in the radial direction and said foils in the circumferential direction form at least one curved segment of the radial foil bearing,
- a first curved segment is formed from a first top foil,
- the first curved segment (a) is fixedly arranged on a carrier foil,
- on the carrier foil a second curved segment is formed from a second top foil,
- the two curved segments are placed successively on said carrier foil so that, when the carrier foil is rolled up, a tubular carrier with the two curved segments is produced and forms the radial foil bearing, and
- the carrier foil is designed as a corrugated foil.
A radial foil bearing, comprising:
- a carrier foil formed from a corrugated foil;
- a first curved segment formed from a first top foil;
- and
- a second curved segment formed from a second top foil, the second curved segment arranged successively on the carrier foil after the first curved segment to form a tubular carrier comprising two curved segments when the carrier foil is rolled.
