  • Dry gas thrust bearing for use in rotating equipment
    Patent number: 8998494
    Abstract: A dry gas thrust bearing is provided for use in rotating equipment and more particularly, this thrust bearing is designed to support compressor/turbine thrust loads in an improved arrangement which does not require oil lubrication and which is designed to support necessary shaft thrust loading by the utilization of a dry gas film. The bearing includes a shaft rotor between two axially movable stators and relies on a dry gas film to separate the rotor and stators. The stators are axially loaded by a double spring package arranged in series wherein a lightly loaded spring engages the stator during zero thrust applications, and as the shaft begins to rotate and encounter axial thrust, a heavier stiffer spring, greater than the thrust load, quickly engages.
