Description

(54) ОПОРА РОТОРА ГАЗОВОЙ ТУРБИНЫ(54) GAS TURBINE ROTOR SUPPORT

Claims (1)

Формула изобретенияClaim Опора ротора газовой турбины, содержащая установленный в корпусе последней 5 корпус подшипника с каналами подвода и отвода воздуха к подшипнику и масляным уплотнениям, отличающаяся тем, что, с целью повышения надежности и эффективности охлаждения, между корпусами Ю подшипника и турбины установлен экран, образующий с корпусом подшипника полость, а с ротором турбины —калиброванную щель, и в корпусе подшипника выполнены калиброванные отверстия, сообщаю15 щие полость с каналами подвода воздуха к уплотнениям.A gas turbine rotor support comprising a bearing housing installed in the housing of the last 5 with air supply and exhaust channels to the bearing and oil seals, characterized in that, in order to increase the reliability and cooling efficiency, a screen is formed between the bearing housing and the turbine forming with the housing bearing cavity, and with the turbine rotor a calibrated slot, and calibrated holes are made in the bearing housing, communicating the cavity with air supply channels to the seals.
