Abstract

Винахід належить до конструкції картера турбомашини, який містить циліндричний отвір (6), що утворює підшипник ковзання для поворотної осі (5) лопатки (3) зі змінним кутом встановлення. Всередині згаданого циліндричного отвору вставлений вкладиш, який складається з металевої гільзи (11), що виконана з однієї циліндричної частини й містить на одному зі своїх кінців фланець (13), виконаний радіально назовні, керамічного кільця (16), закріпленого за допомогою паяння на внутрішній поверхні (11а) згаданої гільзи (11), та керамічної шайби (14), закріпленої за допомогою паяння на зовнішній поверхні фланця (13). Винахід забезпечує необхідну жорсткість вкладиша під час його монтажу та під час роботи турбомашини, завдяки чому знижується небезпека поломок у картері.
