摘要： A rotor and bearing system for a turbomachine. The turbomachine (10) includes a drive shaft (20), an impeller (36) positioned on the drive shaft, and a turbine (34) positioned on the drive shaft proximate to the impeller. The bearing system (44) comprises one gas journal bearing (46) supporting the drive shaft between the impeller and the turbine. The area between the impeller and the turbine is an area of increased heat along the drive shaft in comparison to other locations along the drive shaft. The section of the drive shaft positioned between impeller and the turbine is also a section of the drive shaft that experiences increased stressed and load in the turbomachine. The inventive bearing machine system positions only one radial bearing in this area of increased stress and load.
