ROTOR OF HIGH-TEMPERATURE GAS TURBINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; gas turbines. SUBSTANCE: proposed rotor of high-temperature gas turbine has disks with fitted-on deflectors secured by bolts in hub relative to disks and by bayonet joint over periphery. Deflector is fitted with double axial interference relative to disk: between inner support surface on hub and peripheral end face of deflector, and between contact surfaces of bayonet joint and peripheral end face of deflector. Disk is installed also with double radial fit: on hub - by inner diameter and by inner surfaces of disk radial projections, and in bayonet joint, by outer diameter. Axial interference between inner support surface on hub and peripheral end face of deflector is 0.1 - 2 mm, axial interference between contact surfaces of bayonet joint and peripheral end face of deflector is 0-0.4 mm, and radial clearance by inner surfaces of bayonet joint is 0.01-1.0 mm. EFFECT: improved reliability of gas turbine in operation. 2 cl, 3 dwg
