  • Keyless/grooveless foil bearing with fold over tab
    Patent number: 8672549
    Abstract: An improved air foil bearing assembly is disclosed. The air foil bearing assembly includes a bearing housing having an axially extending bore therein and a shaft arranged within the bore for relative coaxial rotation with respect to the bearing housing. The shaft cooperates with the bearing housing to define an annular gap therebetween. A foil assembly is disposed in the annular gap, including at least one foil having at least one laterally extending tab. The tab is adapted to be received in and extend axially from the annular gap and is further adapted to be bent into frictional contact with an outer surface of the bearing housing to militate against axial movement of the foil.
    Type: Grant
