DRIVE SHAFT OF GEAR BOX OF JET TURBINE ENGINE AUXILIARY MECHANISM Russian patent published in 2016 - IPC F02C7/32 F02C7/36 F02K3/06 

FIELD: engines.

SUBSTANCE: jet turbine engine comprises intermediate case with radial sleeves and drive shaft of gear box of auxiliary mechanisms. Drive shaft runs in radial sleeve, the sleeve includes intermediate bearing for support of the drive shaft. Intermediate bearing includes a plurality of rolling bearings to support drive shaft. Drive shaft comprises first element of a shaft, one end section of which is connected by means of mechanical transmission with shaft turbojet engine, and the second element of the shaft, one end section of which is connected by means of mechanical transmission with gear box. First and second elements of the shaft are compound, in which one end section of the second element of the shaft is inserted in cylindrical hollow end section of the first element of the shaft and which is carried out by means of multiple complementary recess in the first element of the shaft and in the second element of the shaft. Through a plurality of grooves and multiple rolling bearings across passes one and the same plane.

EFFECT: invention allows reducing voltage in the intermediate bearing caused by displacement of two elements of the drive shaft.
