用于空气机中的推力和轴颈空气轴承冷却的推力轴承轴
摘要：
本发明涉及用于空气机中的推力和轴颈空气轴承冷却的推力轴承轴，具体地，一种推力轴承轴具有径向放大的推力盘以被安装在空气循环机中的两个静止壳体表面之间。推力轴承轴的第一部分从推力盘的一个面延伸。第二部分从推力盘的相对的第二面延伸。第二部分具有密封肋以及六个孔。密封肋相比孔离推力盘更近。从第二部分的端部到孔的中心的距离相比从第二部分的该端部到推力盘的第二面的距离的比率在0.20和0.22之间。另外，公开了一种包括该推力轴承轴的空气循环机以及一种将该推力轴承轴组装到空气循环机中的方法。
摘要（英）：

The invention relates to a thrust bearing shaft for thrust and journal air bearing cooling in an air machine. The thrust bearing shaft has a radially enlarged thrust disk to be mounted between two static housing surfaces in an air cycle machine. A first portion of the thrust bearing shaft extends from a first face of the thrust disk. A second portion extends from a second opposed face of the thrust disk. The second portion has sealing ribs and six holes. The sealing ribs are spaced closer to the thrust disk than are the holes. A ratio of a distance from an end of the second portion to a center of the holes compared to a distance from the end of the second portion to the second face of the thrust disk is between 0.20 and 0.22. In addition, an air cycle machine incorporating the thrust bearing shaft, and a method of assembling the thrust bearing shaft into an air cycle machine are disclosed.
