GAS TURBINE ENGINE INTER-ROTOR SUPPORT Russian patent published in 2018 - IPC F02C7/06 F16C25/02 F16C33/24 

FIELD: motors and pumps.

SUBSTANCE: invention relates to the field of aircraft engine construction and can be used in the inter-rotor bearings of gas turbine engines. Inter-rotor support of the gas turbine engine includes a slide bearing, comprising an inner bearing ring, made of a composite material on the basis of a dispersion-hardened reaction-sintered silicon carbonitride and fixed to a low-pressure rotor shaft, outer ring made of a metal-clay-matrix material on the basis of titanium nitride at a certain ratio of components and located inside the high-pressure rotor shaft, and its support has a hinge element, which is a support ring, made of heat-resistant steel, mounted on the outer ring of the bearing. At the same time the outer surface of the support ring is made in the form of a hemisphere, interacting with the corresponding inner surface of the high-pressure rotor shaft.

EFFECT: technical result consists in eliminating the effect of bending moments on the bearing during the working cycle, while simultaneously increasing the wear resistance of the bearing, which ensures an increase in the reliability of the inter-rotor support.
