Abstract
A compliant foil radial bearing (100) comprising: a bushing (110) comprising a bore defined therethrough; a spring foil (120, 130) arranged to conform to a radially inner surface of the bore; a fluid foil (140, 150) arranged to conform to a radially inner surface of the spring foil for rotatably receiving a rotor, wherein: the spring foil comprises one or more retaining portions (160) arranged to extend axially and radially outside the radially inner surface of the bore.
Claims15
A compliant foil radial bearing comprising:
- a bushing comprising a bore defined therethrough;
- a spring foil arranged to conform to a radially inner surface of the bore;
- a fluid foil arranged to conform to a radially inner surface of the spring foil for rotatably receiving a rotor, wherein:
- the spring foil comprises one or more retaining portions arranged to extend axially and radially outside the radially inner surface of the bore.
A method of manufacturing a spring foil for a compliant foil radial bearing, the method comprising:
- forming one or more cutouts within a rectangular section of flat sheet metal, the cutouts comprising first lengths interconnecting second lengths, the first lengths for axial orientation within a bushing of the compliant foil radial bearing and the second lengths for circumferential orientation at axial ends of the bushing;
- and
- forming one or more retaining portions that extend outside the plane of the flat sheet metal for positioning axially outside the second lengths.
