The invention relates to aeronautical engineering, and more particularly to a gas turbine engine with a free turbine. The turbine bearing housing is in the form of a stepped bushing with a supporting flange and a cylindrical flange, the bushing is press-fitted into the gas collector along two cylindrical belts spaced apart, with support along the flanges, mounted between the steps of the bushing is an additional cylindrical shell, a pressure-sealing cavity for supplying cold air, and the oil supply pipe is in the form of channels formed in the body of the bushing. The technical result is an increase in the reliability of the gas collector, and as a result, an improvement in the performance reliability of the engine, an extension in the service life of same, and a simplification and improvement in the quality of the maintenance of same. |
