ABSTRACT:
A journal bearing designed for use with a rotatable shaft of an air cycle machine is disclosed. The bearing includes a journal bearing housing, air bearings for facilitating rotation of the shaft, and a journal bearing shell positioned in the housing. The shell includes a single piece body structure having a first half integral with a second half. The first half includes a first outside end and the second half includes a second outside end. The first half is sufficiently spaced from the second half for supporting and aligning the air bearing for supporting the rotatable shaft. The first and second integral halves define a continuously formed inner diameter adapted to receive the air bearings between the rotatable shaft and the inner diameter for facilitating rotation of the shaft relative to the body structure. The continuously formed inner diameter extends from the first outside end to the second outside end and an outer surface for placement and securement in the journal bearing housing of the air cycle machine is provided.
