摘要
A rotating assembly of turbomachinery is provided. The rotating assembly includes a plurality of components mounted on a rotatable shaft within a housing of the turbomachinery and at least one foil journal bearing assembly for mounting the rotatable shaft to the housing. The foil journal bearing assembly includes an annular bearing carrier mounted to the housing. An annular bearing sleeve is disposed within the annular bearing carrier and attached thereto. The annular bearing sleeve is lined with a plurality of foils. A journal is mounted to the rotatable shaft. The journal has an outer surface engaging the foils. The journal is configured to at least one of the following: resist operational deflection thereof and reduce the effects of misalignment. A method for producing the journal of the foil journal bearing assembly is also provided.
