ROTOR UNIT OF TURBOMACHINE WITH TWO DISKS PROVIDED WITH BLADES AND SEPARATED BY SPACER Russian patent published in 2008 - IPC F01D5/06 

FIELD: mechanical engineering; turbomachines.

SUBSTANCE: proposed rotor unit of turbomachine has two disks provided with blades, and spacer. Slots are made in one of disks to fit roots of blades. Spacer contains envelope enclosing the disk and tenons getting into slots and provided with inner radial thrust surfaces. And outer axial thrust surfaces. Inner radial thrust surfaces of tenons rest on mating surfaces formed on one of disks. Outer axial thrust surfaces include first outer axial thrust surfaces and second outer axial thrust surfaces opposite to first surfaces. First outer axial thrust surfaces thrust against one of disks. Second outer axial thrust surfaces thrust against seal coupled with other disk. Said seal is designed to hold blades of other disk.

EFFECT: facilitated assembling of rotor unit, increased strength of spacer, reduced mass of spacer.
