РОТОР ПАРОВОЙ ТУРБИНЫ (ВАРИАНТЫ)

摘要

FIELD: nuclear power stations. ^ SUBSTANCE: invention relates to rotor mainly with fork connection of rims with working blades of high-pressure compartments and medium-pressure compartments of steam turbine, particularly, to powerful wet-steam turbine of nuclear power station. Proposed rotor of steam turbine has shaft with fitted-on disks. Rims of fitted-on disks are connected with working blades by split joints. Fitted-on disks are two-rim, each being provided with asymmetrical hub with end elongated towards direction of disk fitting. Key connecting disk and shaft is arranged under elongated end of disk. ^ EFFECT: simplified design and assembling, improved reparability and reliability of steam turbine rotor in service. ^ 2 cl, 2 dwg
