FIELD: energy.
SUBSTANCE: invention relates to power engineering. Disclosed is a high-pressure turbine support containing a bearing housing with power spokes, fixed on the turbine housing, bearing outer race installed in the housing between the thrust collar and nut, and the roller bearing interacting with a turbine rotor. Support is equipped with intermediate race of material of hardness, comparable with the bearing outer race, there are ledges on one end of intermediate race, and there are mating ledges slots in the thrust collar, intermediate race is installed between housing and outer race, race ledges enter the slots in the thrust collar.
EFFECT: invention ensures uninterrupted operation of gas-turbine plant, excluding critical vibrations after several vibrations occurring during operation and scheduled stops and increasing overhaul life by 50,000 hours.
