  • SYSTEMS AND METHODS FOR INTEGRALLY GEARED CENTRIFUGAL COMPRESSOR TO MAINTAIN ROTOR CONCENTRICITY WITH DIFFERING PINION GEAR TOOTH COUNTS
    Publication number: 20240018976
    Abstract: Integrally geared centrifugal compressor systems are described that include eccentric cartridges that house bearings and seals to maintain rotor concentricity for a variety of pinons integrated in a fixed gearbox design to provide multiple impeller speeds with a single gearbox design. In an aspect, a system includes, but is not limited to, a pinion configured to be rotated by a bull gear about a rotational axis; a rotor coupled to the pinion; and an eccentric cartridge configured to house a bearing assembly through which the rotor extends to support rotation of the rotor, the eccentric cartridge having an outer surface and an inner surface, wherein the inner surface is eccentric relative to the outer surface to align the rotational axis with a center axis of the bearing assembly.
    Type: Application
