FIELD: engines and pumps.
SUBSTANCE: gas turbine drive comprises inlet device, radial-flow compressor, combustion chamber, turbine, outlet device and reduction gear. Intermediate housing accommodating torque transmission is arranged between reduction gear and inlet device to make common oil chamber there between. Intermediate housing incorporates extra flange with through hole to allow connection with mate flange of extra ganging module housing. Extra ganging module comprises drive gear to engage with, at least, two gear wheels, one being engaged with gear connected with starter. Another wheel of said extra module allows transmitting torque to extra driven assemblies. Said extra module is connected with torque transmission via spring and does not depend upon reduction gearbox gear ratio. Said spring passes through opening in intermediate housing wall to be connected with extra module drive gear and torque transmission bevel gear. Said bevel gear is fitted on torque transmission assembly with its central axis aligned with gas turbine drive rotational axis. Intermediate shaft is engaged with drive shaft and reduction gear drive wheel to transmit torque from gas turbine.
EFFECT: higher performances and reliability, longer life.
