Abstract
A composite resilient mount for rolling element bearings, comprising a composite hoop portion, and including a plurality of circumferentially dispersed inner pads and outer pads defining a plurality of arcuate beam portions disposed circumferentially between adjacent pads. The hoop portion and the inner and outer pads, may comprise a circumferentially wound fiber, such as a carbon fiber, and a resin. The inner and outer pads may be rounded, feathered or otherwise configured to eliminate edges from the inner and outer pads, thereby preventing damage to adjacent components. A method for providing damping to a rolling element bearing is also disclosed.
Claims35
A mount, comprising:
- a hoop portion having a hoop external surface and a hoop internal surface;
- a plurality of inner pads dispersed circumferentially on said hoop internal surface;
- and
- a plurality of outer pads dispersed circumferentially on said hoop external surface, wherein:
- each of said inner pads and said outer pads include peripheral pad rounded portions, and
- said mount comprises a composite material, wherein said composite material includes fibers.
A mount for a bearing, comprising:
- a hoop portion having a hoop external surface and a hoop internal surface;
- a plurality of inner pads dispersed circumferentially on said hoop internal surface;
- and
- a plurality of outer pads dispersed circumferentially on said hoop external surface, wherein said mount comprises a composite material comprising circumferentially wound fibers impregnated with a resin.
A composite resilient mount, comprising,
- a hoop portion comprising at least one layer of circumferentially wound fibers impregnated with a resin, said hoop portion having a hoop internal surface and a hoop external surface;
- a plurality of inner pads disposed on said hoop internal surface;
- and
- a plurality of outer pads disposed on said hoop external surface, wherein:
- the total number of said inner pads equals the total number of said outer pads,
- each of said outer pads is interspersed between an adjacent pair of said inner pads to define a plurality of arcuate beam portions circumferentially disposed between said inner pads and said outer pads, and
- each of said inner pads and said outer pads include peripheral pad rounded portions.
A bearing assembly, comprising:
- an inner raceway;
- an outer raceway disposed radially outward from said inner raceway, said outer raceway having an outer raceway outer surface;
- a composite resilient mount disposed radially outward from said outer raceway;
- and
- a housing having a housing inner surface, said outer raceway outer surface and said housing inner surface jointly defining an annular space, wherein said composite resilient mount is disposed within said annular space, and said composite resilient mount comprises:
- a hoop portion having a hoop internal surface and a hoop external surface,
- a plurality of inner pads dispersed circumferentially on said hoop internal surface of said composite resilient mount, and
- a plurality of outer pads dispersed circumferentially on said hoop external surface of said composite resilient mount,
- wherein said composite resilient mount comprises a composite material comprising circumferentially wound fibers impregnated with a resin.
An apparatus, comprising:
- a rotor;
- a rolling element bearing for supporting said rotor, said bearing comprising an outer raceway;
- a housing for said bearing;
- and
- a composite resilient mount disposed external to said outer raceway, wherein said composite resilient mount comprises:
- a hoop portion having a hoop internal surface and a hoop external surface,
- a plurality of inner pads dispersed circumferentially on said hoop internal surface of said composite resilient mount, and
- a plurality of outer pads dispersed circumferentially on said hoop external surface of said composite resilient mount, wherein said composite resilient mount comprises a composite material, and said composite material comprises circumferentially wound fibers and a resin.
