  • Air bearing and antifriction bearing assembly
    Patent number: 4394091
    Abstract: A hybrid bearing assembly includes a shaft rotatably supportable within a shaft housing by a hydrodynamic foil bearing acting in parallel with an antifriction bearing. The shaft is supported solely by the antifriction bearing at zero and low shaft speeds, and is supported solely by the foil bearing at the running speed. As the shaft accelerates from low speeds through running speed, support of the shaft is shared between the antifriction bearing and the foil bearing which act in parallel.
