Weight reduction for journal air bearing

摘要

A hydrodynamic fluid film journal bearing system (10) includes a journal sleeve (12) and one or more hydrodynamic fluid film foils positioned at least partially within the journal sleeve. The journal sleeve defines an inner diameter surface, an outer diameter surface (14), a wall thickness between the inner and outer diameter surfaces, and opposite first (18) and second (20) ends. The wall thickness of the journal sleeve is reduced at a first region located between the first and second ends, and a chamfered region (66) is formed on the outer diameter surface of the journal sleeve between a first o-ring land (62) and the first end (18) of the journal sleeve (12).
