FIELD: power engineering.
SUBSTANCE: invention relates to the field of power engineering, namely to assemblies with axial petal gas-dynamic bearings, and can be used as supports for high-speed turbomachines, in particular in turbine generators. The thrust assembly of the turbomachine contains a stator housing with the first (1) and second wheels located on both sides of it with the back side to the stator housing of the turbomachine and connected by a shaft, and located between the stator housing and the first (1) and second wheels two axial petal gas-dynamic bearings. Both axial petal gas-dynamic bearings are made consisting of an annular thin-walled disk (6) with elastic profiled plates (7) attached to it, forming a friction pair with the rear sides of the wheels. At least one of the axial petal gas-dynamic bearings on the outer surface of the annular thin-walled disc (6) of the bearing, which is as far as possible from its center, has at least three antennae (9) bent to the inoperative side (10) of the bearing at a right angle or angle close to it. In the surface of the stator housing there are grooves (11) corresponding to the size of the antennae (9), into which the said antennae (9) are inserted.
EFFECT: invention increases the reliability of assembly and operation of the thrust assembly while simplifying the design.
