Beschreibung
Zusammenfassung:	FIELD: mechanical engineering. SUBSTANCE: invention relates to gas turbine engine. Said support for two rotor gas turbine engine has high pressure rotor journal, pre-oil space, oil space and intershaft space formed by journal and shaft of high pressure rotor. Bearing inner race and labyrinth seal separating pre-oil and oil spaces is installed on outer surface of journal. Impeller made in form of hub with ribbed disk is installed between spaces. Ring groove is made on inner surface of journal from side of intershaft space. Ring space forms open cavity in journal which communicates with oil space through holes in journal and holes in impeller. EFFECT: improved reliability of support and increased service life owing to prevention of coking of support members. 4 cl, 5 dwg
