Abstract
A 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.
