FIELD: engines and pumps.SUBSTANCE: turbine rotor comprises some working blades. Said blades are arranged on appropriate turbine disc in rows of working blades. Turbine disc sides have several seal plates shaped to ring sections. Said plates are fitted in turbine disc groove extending circumferentially. Seal plate side facing the turbine has circumferentially extending edging spaced from seal plate inner edge. Locking element is arranged between said edging and turbine disc groove sidewall. Said edging extends circumferentially over the entire length of seal plate. Seal locking elements abut on each other circumferentially. Seal plate recess extending, in fact, circumferentially on side facing the turbine axis to interrupt appropriate edging. Recess geometry allows fitting locking through recess and into turbine disc groove. Invention covers also gas and steam turbines comprising above described rotor.EFFECT: simplified assembly of turbine rotor.10 cl, 14 dwg |
