FIELD: mechanical engineering; supports for high-speed turbo-unit rotors.
SUBSTANCE: proposed sliding support includes shaft with turbine wheel secured on it and bush secured in housing of machine. Said bush made from anti-friction material is stepped in form; cylindrical and end surfaces of this bush are working surfaces of sliding radial axial sliding bearing provided with flow lubrication; end face of turbine wheel has circular projection whose surfaces are used as journal and pivot of sliding bearing.
EFFECT: increased carrying capacity; enhanced vibration resistance; reduced overall dimensions; enhanced reliability and durability; reduced usage of materials.
