FIELD: machine building.
SUBSTANCE: system of turbomachine rotor supports comprises a compressor support, a turbine support and a support installed between them, at the same time the turbine support comprises a casing, a radial bearing arranged with rotary segment blocks, a support element made with holes, a spherical section and a cavity communicated with holes, a bushing made of an inner bushing with ledges and a covering cylindrical elastic element inserted one into the other, and an oil damper arranged between the bushing and the spherical section of the support element and with a gap relative to the inner surface of the support casing made in the form of bushings inserted one into the other as capable of rotation and contacting with each other along the sphere, and fixed on the support element with the inner bushing, at the same time the support element is made as capable of inclination relative to the longitudinal axis of the turbomachine and is connected to the support casing along the spherical section and with the help of screw elements located in the support casing between the bushing ledges and contacting with the elastic element.
EFFECT: simplified adjustment of bearing alignment and compensation of deviations of the support axis from the rotor axis of rotation.
