The assembly has a support bush, and a sealing ring (11) with sealing elements constituting a piece distinct from the support bush and connected on the support bush. The support bush is formed to block the sealing ring in rotation and partly in translation when the sealing ring is positioned on the support bush. The support bush has a succession of notches (12a) and external projecting zones (12b) cooperated with a succession of complementary notches (13a) and complementary projecting zones (13b) of annular interior periphery of the ring to ensure blocking in rotation of the sealing ring. An independent claim is also included for a method for testing sealing at air/oil interface of a high pressure environment of a gas turbine. |
