INTERNAL COMBUSTION ENGINE GAS TURBOSUPERCHARGER Russian patent published in 2002 - IPC

FIELD: mechanical engineering; superchargers of internal combustion engines. SUBSTANCE: proposed gas turbosupercharger has rotor with compressor blades and gas turbine blades fitted on, support-thrust sliding bearings arranged at rotor ends, lubrication system providing operation of bearings and including pipelines, strainer and fine filters. Support-thrust sliding bearings operating on low-viscosity liquid are made in form of self- aligning segments arranged in housing in contact with thrust disk installed on shaft bushing inside the housing. Thrust disk has axial and radial lubricant feed-in channels. Rings made of antifriction material and installed between housing, thrust disk and shaft are provided with through longitudinal slots, outer conical surfaces engaging with conical surfaces of housing, and inner cylindrical surfaces engaging periodically with shaft bushing. Shells are installed between housing and shaft bushing in end face part of housing of support-thrust sliding bearing. Lubrication system of support-thrust sliding bearing is connected to cooling system of internal combustion engine through non-return shutoff valves. EFFECT: enhanced reliability, increased service life and improved performance characteristics of turbosupercharger at considerable reduction of mass and overall dimensions. 2 cl, 1 dwg
