Expansion turbine for cooling e.g. hydrogen, has axial bearings to receive disk, where disk is in form of spindle such that convex elastic deformation is observed in active bearing surfaces of disk when disk is operated at high speed

摘要

The turbine has an upper axial bearing (3) and a lower axial bearing (4) for receiving an axial bearing disk (2'). The disk (2') is in the form of an axial bearing spindle such that a convex elastic deformation is observed in active bearing surfaces of the disk when the disk is operated at high peripheral speed. The disk is practically installed in the middle of total length of a rotor shaft (1).
