FIELD: aircraft industry; gas-turbine engines.
SUBSTANCE: device to transmit torque from compressor shaft to gas turbine engine auxiliaries gearbox contains spur driven gear and bevel pinion. Intermediate shaft is installed by means of splines between spur gear and bevel pinion. Intermediate shaft is provided with inner ring spaces on ends connected by radial channels with spaces of spline joints. Spur gear and bevel pinion are provided with inner beads whose diameter is smaller than inner diameter of spaces of splines of intermediate shaft.
EFFECT: improved reliability of operation of device owing to constant pumping oil to spline joints and removal of spline wear products and lubricating and cooling of splines.
