FIELD: engines and pumps.SUBSTANCE: coupling of composite rotor of gas generator of gas turbine engine comprises means for transmitting torque and axial coupling of two coaxial rotating wheels in form of moving elements arranged in annular grooves made in journal of centrifugal compressor wheel and stub axle of turbine gas generator. Moving in circular recesses impeller and turbine wheel engagement elements are made as spring-loaded segments, having on side of centrifugal wheel angular chamfers, congruent skew in groove of turbine wheel. Journal of centrifugal wheel with coupling elements is arranged in hole of trunnion turbine wheel. On end side of journal of turbine wheel there is a pressed plastic ring in contact with end surface of centrifugal wheel.EFFECT: invention ensures rigid connection of wheels of composite rotor of gas turbine engine with reduced axial dimensions and weight of said rotor.2 cl, 1 tbl, 5 dwg |
