METAL CERAMIC ROTOR FOR TURBO COMPRESSOR Russian patent published in 1995 - IPC

FIELD: gas turbine engine engineering. SUBSTANCE: conical journal 2 of ceramic turbine 1 is arranged in the space defined by bore of sleeve 5 of metal shaft 4 of compressor 5. The sleeve and journal are interconnected with bayonet joint formed by projections and hollows. Metal stop ring 10 having radial recesses 14 on face 13 is secured inside the sleeve by pins 11. The overrunning thrust clutch is formed by race 16 with rolling bodies and recess 14 on pin 2 and disk 10. The centering conjugated surfaces 19,20 of journal 2 and sleeve 5 can be spherical. The torque is transmitted from turbine 1 to compressor 3 through rolling bodies 15 and pins 11. EFFECT: enhanced reliability. 5 dwg
