INCORPORATION OF GEAR TRAINS IN PINION WALL IN GEARBOX FOR TURBOMACHINE Russian patent published in 2019 - IPC F16H1/28 F16H3/44 

FIELD: machine building.

SUBSTANCE: group of inventions relates to machine building. Drive train for an aircraft comprises a plurality of main pinions, wherein the first main pinion comprises a wall defining an inner volume, on the outer surface of the wall there is an outer ring gear which engages with at least the second main pinion, a gear system is built into the internal volume, which includes an element forming the crown gear, on the inner surface of which an internal gear ring is made. First main pinion and gear system are designed in such a way as to form together a multiplier or reducer and ensure the transfer of mechanical energy between the driving element and the driven element. Gear system comprises at least two satellite gears, an element forming a carrier, and a solar gear ring formed on the shaft connected to the driving element or to the driven element. Satellite gears engage with an internal gear ring and with a solar gear ring. Element forming the crown gear is the wall of the first main pinion, the element forming the carrier is fixed relative to the body of the aircraft. Also disclosed is an accessory gearbox comprising a drive train.

EFFECT: reduced size of the device.

8 cl, 8 dwg
