摘要： A counter-flow recuperator formed from annular arrays of recuperator core segments. The recuperator core segments are formed from two opposing sheets of fin fold material coined to form a primary surface zone disposed between two flattened manifold zones. Each primary surface zone has undulating corrugations including a uniform, full height central portion and a transition zone disposed between the central portion and one of the manifold zones. Corrugations of the transition zone rise from zero adjacent to the manifold zone and increase along a transition length to full crest height at the central portion. The transition lengths increase in a direction away from an inner edge containing the air inlet so as to equalize air flow to the distal regions of the primary surface zone.

摘要： The improved bearing system includes a pair of axially split and generally cylindrical cartridges having respective bearing units configured to be mountable to a common axial shaft. An annular channel is generally formed from one of the cartridges for selectively receiving a preload ring. An annular groove is formed from a portion of the other cartridge and sized to slidably receive the preload ring. A preload element is disposed within the annular groove and axially compressed between a preload surface of the annular groove and the preload ring. The preload element maintains a simultaneous axial preload thrust on the bearing cartridges and respective bearing units in inwardly opposite axial directions.

摘要： A small gas turbine generator set comprising a rotating group and combustor contained within a circumferential recuperator. The rotating group comprises an alternator rotor on a common shaft with a turbine wheel and compressor impeller, supported by double acting complaint foil thrust bearings and a radial compliant foil bearing. The circumferential recuperator consists of a plurality of apertured boundary foils having embossments for structurally spacing the foils apart, arranged to provide the flow channels, manifolds, and structure to permit the existence of differential pressure between each surface of the foil. The circumferential recuperator is unitarily constructed surrounding the rotating group and combustor wherein the inflowing air is heated by the recuperator before entering the combustor. Due to the intercompatibility and modularity of the components, the air flow path associated with the compressor discharge and the turbine inlet is formed upon installation of the rotating group and the recuperator and by final assembly of the combustor unit which forms a final enclosure for the turbine inlet air. The configuration of the circumferential recuperator provides improvement in engine performance by improving heat transfer effectiveness and additionally acts to absorb sound as well as to safely insulate the surrounding environment should the rotating group fail and be centrifugally driven outside of its primary containment.

摘要： An improved bearing system for use in high speed rotating machinery, such as a turbocharger, wherein a shaft is rotatably supported by a floating bearing cartridge having axially spaced angular contact bearings each with a set of bearing balls supported between inner and outer races. The bearing cartridge includes an inner spacer sleeve for axially spacing the inner bearing races, and a rotationally floating outer sleeve having a pair of radially inwardly open grooves for removably receiving snap-type retaining rings which engage and axially space the outer bearing races. The axial dimension of the inner spacer sleeve is elongated slightly relative to an axial dimension defined between outboard faces of the installed retaining rings, thereby slightly unloading the sets of bearing balls from their respective outer bearing races. Such slight axial unloading enhances smooth-running operation with minimal bearing wear, while accommodating transient loads during operation.

摘要： An improved bearing system is provided for use in high speed rotating machinery such as a turbocharger, wherein a turbocharger shaft is rotatably supported at opposite ends by a pair of angular contact bearings subjected to a predetermined and substantially constant thrust pre-load. The angular contact bearings are carried respectively within a pair of generally cylindrical bearing sleeves which cooperatively define an axially split bearing carrier mounted within a turbocharger housing. A spring reacts between these bearing sleeves for applying a substantially constant axial thrust pre-load transmitted by the bearing sleeves to the angular contact bearings. The mechanical spring thrust pre-load may be supplemented or substituted by an hydraulic axial thrust load attributable to oil circulated through the split bearing carrier.
