摘要： A bidirectional radial bearing for rotatably supporting a rotor or shaft may include a bushing (12) with an interior bore having one or more antirotation retainers (22) that may be equally spaced and extend the axial length of the interior bore. The interior bore of the bushing may be formed into a plurality of lobes (25). The interface of adjacent lobes and a compliant foil (14) and a foil underspring (16) form symmetrical converging wedges. The combination of the lobed bore and the compliant foil and foil underspring establish symmetrical converging wedges surrounding the rotor or shaft. In another aspect of the present invention, a single compliant foil may combine with the lobed bore and one or more foil underprings to form two or more symmetrical converging wedges. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
摘要翻译：用于可旋转地支撑转子或轴的双向径向轴承可以包括具有内孔的衬套（12），所述内孔具有一个或多个防旋转保持器（22），所述防旋转保持器可等间隔并延伸所述内孔的轴向长度。衬套的内孔可以形成多个凸角（25）。相邻的叶片和柔顺箔片（14）和箔片下端（16）的界面形成对称的会聚楔形物。裂缝孔和柔性箔片和箔片下端的组合构成围绕转子或轴的对称的收敛楔块。在本发明的另一方面中，单个柔性箔片可以与凸起的孔和一个或多个箔片底部组合以形成两个或更多对称的会聚楔形物。要强调的是，该摘要被提供以符合要求摘要的规则，这将允许搜索者或其他读者快速确定技术公开的主题。提交它的理解是，它不会用于解释或限制权利要求的范围或含义。

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.
摘要翻译：用于涡轮机的转子和轴承系统。涡轮机（10）包括驱动轴（20），定位在驱动轴上的叶轮（36）以及定位在驱动轴上靠近叶轮的涡轮（34）。轴承系统（44）包括在叶轮和涡轮机之间支撑驱动轴的一个气体轴颈轴承（46）。与驱动轴上的其他位置相比，叶轮和涡轮之间的区域是沿驱动轴增加的热量区域。位于叶轮和涡轮机之间的驱动轴的部分也是驱动轴的一部分，其在涡轮机中经受了增加的应力和负荷。本发明的轴承机械系统仅在这个增加的应力和载荷区域内定位一个径向轴承。
