BOX FOR INSTALLATION OF AUXILIARY EQUIPMENT ON GAS TURBINE ENGINE CONTAINING MAGNETIC REDUCTION GEAR Russian patent published in 2019 - IPC F02C7/32 

FIELD: machine building.

SUBSTANCE: box for installation of auxiliary equipment on engine with shaft, which is a gearbox of units for turbojet or turboprop engine or reduction gear for turboprop engine, includes auxiliary device, input gear wheel, input shaft, reduction gear with magnetic gear transmissions, as well as housing. Auxiliary device comprises output shaft. Input gear wheel on one side is rotated by motor shaft at engine shaft speed and, on the other side, is connected to output shaft of auxiliary device to rotate it at preset output speed. Input shaft is rotated by input gear wheel with preset input speed. Reduction gear with magnetic gearing is installed between input shaft and output shaft so that input speed differs from output speed. Reduction gear with magnetic gear transmissions comprises inner rotor fixed on input shaft; external rotor fixed on output shaft; and a stator fixed relative to the box body and installed between the inner rotor and the outer rotor. Inner rotor, outer rotor and stator are coaxial with input shaft and output shaft.

EFFECT: invention simplifies installation of auxiliary devices on the box for auxiliary equipment.
