초록

A rotor and bearing system for a turbomachine. The turbomachine includes a drive shaft, an impeller positioned on the drive shaft, and a turbine positioned on the drive shaft proximate to the impeller. The bearing system comprises one gas journal bearing 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 se...

청구항

What is claimed is: 1. A bearing system for a turbomachine, the turbomachine including a powerhead assembly having a shaft and a location of increased heat, the bearing system comprising only one gas bearing positioned in the location of increased heat, the only one gas bearing positioned to support the shaft and further including a gas thrust bearing positioned remote from the location of increased heat. 2. The bearing system of claim 1, wherein the only one gas bearing is a radial bearing. 3. The bearing system of claim 2, wherein the turbomachine...
