FIELD: engine building.
SUBSTANCE: group of inventions relates to gear boxes for an aircraft gas turbine engine. Gear box comprises drive shaft (12), secondary drive shaft (24), which is connected to drive shaft (12) via reduction gear (26), and output shafts (16), each of which is connected to drive shaft (12) or to secondary drive shaft (24) through system of conical gear transmissions. Reduction gear (26) comprises intermediate shaft (28), first end (28a) of which is connected to drive shaft (12) through first gear (30) of gear transmissions and second end (28b) of which is connected to secondary drive shaft (24) through second stage (32) of gear transmissions. Intermediate shaft (28) is installed with possibility of rotation in drive box around its main axis (B), oriented essentially perpendicular to main axis (A) of drive shaft (12). Also disclosed is an aircraft gas turbine engine comprising said drive box.
EFFECT: simplified design and reduced weight of the box of drives, as well as increased efficiency of the box.
