摘要： A thrust shaft for a fan has a shaft body with an enlarged disk adjacent one axial end to provide a rotating surface in a pair of thrust bearings. A first cylindrical portion extends from the disk in a first direction, and a second cylindrical portion extending from the disk in a second opposed direction. The second cylindrical portion has a hollow bore, and there are a plurality of holes extending through the second cylindrical portion to communicate an outer periphery with the bore. A ratio of the diameter of the bore to a diameter of the plurality of air holes is between 6.60 and 7.00. A ratio of an overall length of the second cylindrical portion, and a distance from a face of the enlarged disk to a center of the holes is between 14.4 and 15.2. A thrust bearing assembly, a fan, a cabin air supply system, and a method are also disclosed.

摘要： An air cycle machine includes a bearing housing with a shaft bore. A rotor shaft is arranged in the shaft bore and includes knife edges extending from the rotor shaft. A seal engages the shaft bore and includes an outer diameter and an inner diameter providing a seal land axially aligned with the knife edges. A radial clearance between the seal land and the knife edges is nominally 0.006 inch. The inner diameter is arranged between lateral sides of the seal that define a width. In one example, a tapered surface extending at an angle relative to the outer diameter from the lateral side to the seal land, the tapered surface facing the large end. The outer diameter to the inner diameter provides a first ratio of 1.25-1.28, and the inner diameter to the width provides a second ratio of 4.33-5.58.

The ramped surface leads into a second cylindrical portion of the shaft has a large outer diameter that is greater than the diameter of the first cylindrical portion. There are twelve air holes formed to extend into an interior of the second cylindrical portion. A bore diameter is defined to an inner periphery of the second cylindrical portion at the location of the air holes. A ratio of the bore diameter to a diameter of the air holes is between 6.30 and 6.54. In addition, a bearing assembly, a compressor, and a method of incorporating an air bearing shaft into a compressor are all disclosed and claimed.

摘要： A compressor rotor compresses air and delivers the compressed air to a downstream inlet and across a turbine rotor. A shaft rotates with the turbine rotor and the compressor rotor. The shaft is hollow with an inner bore and an outer periphery. At least one journal bearing supports a portion of the shaft, and has an inner bore spaced from the outer periphery of the shaft. A cooling air path is provided between the shaft outer periphery and the bearing inner periphery, and along a length of the bearing to at least one connection hole. The connection hole provides cooling air from an outer periphery of the shaft to the inner bore of the shaft. In a separate feature, a shaft for use in an air supply machine includes a hollow interior, with such a connection hole.
