ASSEMBLY FOR AIRCRAFT GAS-TURBINE ENGINE AND METHOD OF ITS MOUNTING Russian patent published in 2018 - IPC F01D25/16 F02C7/32 

FIELD: internal combustion engines.

SUBSTANCE: assembly for an aircraft gas-turbine engine comprises a rolling bearing bracket and a bearing located in its inner space, rotary assembly comprising a first gearwheel and a mechanical power take-off housing intended to be rotated by a gas generator, mechanical power take-off shaft and means for mounting the mechanical power take-off housing on the bearing support. Mechanical power take-off housing is located in the inner space of the bearing support and comprises a housing in which a second gearwheel is inserted mating with the first gear. Mechanical power take-off is installed in the mechanical power take-off housing, rotated by the second gear, passing through a first bearing support opening and rotating the engine accessory drive housing. Means for mounting the mechanical power take-off pass through a second opening on the bearing support configured so as to allow the housing to be inserted into the inner space of the bearing support. When mounting the said assembly, the power take-off housing is inserted into the inner space through a second opening formed on the bearing support and a power take-off shaft is inserted into the power take-off housing through the first opening in the bearing support. Another invention of the group relates to an aircraft gas-turbine engine comprising the above-mentioned assembly.

EFFECT: group of inventions provides the simplified mounting and dismantling of a mechanical power take-off housing on the gas-turbine engine.
