US 12,025,025 B2 · Turbine engine rotor element assembly equipped with a sealing device

Abstract

A turbine engine assembly including a first rotor element and a second rotor element extending around a longitudinal axis X and coupled to one another by a gear coupling, the first rotor element including teeth and the second rotor element including complementary teeth which extend along the longitudinal axis and form the gear coupling. The first and second rotor elements each include a first and a second radial flange which are annular and arranged facing one another, and the assembly includes a sealing device configured to ensure that the gear coupling is sealed at the first and second flanges.

Dependent claims

A turbine engine assembly comprising a first rotor element and a second rotor element which extend about a longitudinal axis X and which are coupled to one another by means of a toothed coupling allowing the torque transmission between the first and second rotor elements, the first rotor element and the second rotor element respectively comprising a first radial flange and a second radial flange which are annular and which are arranged opposite one another,

wherein the first rotor element comprising teeth and the second rotor element comprising complementary teeth, the teeth and complementary teeth extending along the longitudinal axis form the toothed coupling, and in that the assembly comprises a sealing device configured so as to ensure a sealing of the toothed coupling at the level of the first and second flanges.

A method for mounting a turbine engine assembly, said turbine engine assembly comprising a first rotor element and a second rotor element which extend about a longitudinal axis X and which are coupled to one another by means of a toothed coupling allowing the torque transmission between the first and second rotor elements, the first rotor element and the second rotor element respectively comprising a first radial flange and a second radial flange which are annular and which are arranged opposite one another,

wherein the first rotor element comprising teeth and the second rotor element comprising complementary teeth, the teeth and complementary teeth extending along the longitudinal axis form the toothed coupling, and in that the assembly comprises a sealing device configured so as to ensure a sealing of the toothed coupling at the level of the first and second flanges, wherein the method comprises:
a step of providing the sealing device, and
a step of placing the sealing device at the level of the first and second radial flanges to impede a fluid circulation through the toothed coupling.
