CENTRIFUGAL ROTOR WHEEL AND PROCEDURE FOR ITS FABRICATION Russian patent published in 2011 - IPC F04D29/22 F04D29/41 B23P15/02 

FIELD: machine building.

SUBSTANCE: centrifugal rotor wheel consists of driving disk 2 made integral with hub 1, covering disk 3 with central inlet orifice 4 and even number of blades 5 with thrust and back faces 6, 7 and inlet and outlet edges 8, 9; also, blades are arranged between disks 2, 3. Disks 2, 3 are made integral with blades 5. On disk 3 there are axial-symmetric made slots 10 restricted with side 6 of each even blade 5 and nearest to it side 7 of neighbour blade 5, with external diameter D of disk 3 and diametre d of orifice 4. On disk 2 there are axial-symmetric made slots 11 restricted with side 6 of each odd blade 5 and nearest to it side 7 of neighbour blade, with external diameter D of disk 2 and internal outline 12 spaced from axis of wheel not further, than radius R of crossing of edges 8 of blades 5 with internal surface of disk 2.

EFFECT: reduced disk losses, compensation of axial force and raised processability of fabrication.
