TURBOMACHINE ROTOR Russian patent published in 2003 - IPC

FIELD: power engineering. SUBSTANCE: rotor has at least two disks and intermediate ring, all provided with pairs of mating seating surfaces and also with at least one pair of thrust end mating surfaces. One of mating seating surfaces is conical in shape expanding toward point where thrust end surface of intermediate ring is pressed to that of disk. Mating seating surface paired with conical mating seating surface may be also conical in shape. One of mating seating surfaces of other pair may be also conical. Both mating seating surfaces of other pair may be conical in shape. Pairs of mating seating surfaces may be formed by surfaces of projections or slots on disks and/or on intermediate rings. EFFECT: enhanced service life and efficiency, facilitated assembly and disassembly o turbomachine. 5 cl, 2 dwg
