CONNECTING ASSEMBLY OF ROTORS OF COMPRESSOR AND TURBINE OF GAS TURBINE ENGINE Russian patent published in 2015 - IPC F02C7/36 F01D5/02 

FIELD: machine building.

SUBSTANCE: connection assembly of rotors of the compressor and turbine of the gas turbine engine contains compressor clutch installed on the intermediate shaft, turbine shaft, tension puller, lock pipe, and regulating bushing and stop nut. The turbine shaft is installed on the intermediate shaft and is connected with it in circle direction by means of the spline joint, and tension puller is connected in circle direction with the lock pipe by means of the spline joint. The compressor clutch is installed on the turbine shaft and is connected with it in axial direction by means of the mentioned tension puller, and in circle direction byy means of the spline joint. The regulating bushing is installed on the turbine shaft by means of the thread connection and is in contact with the intermediate shaft over the end faces, and in circle direction the regulating bushing is connected with the compressor clutch by means of the spline joint. The stop nut is installed on the intermediate shaft by means of the tread connection and is connected in circle direction with the compressor clutch by means of the spline joint. The end faces of the stop nut and the compressor clutch are in contact with the end face of the regulating bushing.

EFFECT: invention ensures increased service life of the connecting assembly of the rotors of the compressor and turbine, reduces its weight and size, simplifies assemblage.
