Abstract
The utility model relates to a turbine outer ring, which comprises a turbine outer ring substrate and a metal prismatic grid. The essential points are as follows: the metal prismatic grid is fixedly connected with the inner edge of the turbine outer ring substrate, and powder filling is filled in the metal prismatic grid; and the powder filling, the metal prismatic grid and the turbine outer ring substrate are fixedly connected into a whole after high-temperature sintering. The utility model has the advantages of simple structure, easy manufacture, wear resistance, strong resistance to fuel gas erosion and safe and reliable use, and a coating can not peel off and fall off.
Description
Technical field
The utility model relates to a kind of turbine outer shroud, is specifically related to a kind of gas turbine outer shroud of aeroengine.
Background technique
Gas turbine is one of aeroengine three big parts, gas turbine includes gas turbine outer shroud and turbine rotor blade, in order to reduce the gas leakage between turbine outer shroud and the turbine rotor blade, normally on the turbine outer shroud, directly add coating or add the structural type of honeycomb, coating or honeycomb fall piece easily, come off and anti-combustion gas scouring capability poor.Simultaneously, increase tip clearance, reduce engine performance because this turbine outer shroud when scraped finish occurring with the turbine rotor blade blade tip, can damage turbine rotor blade, even the damage motor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of wear-resisting, the turbine outer shroud that coating is not fallen piece, do not come off, anti-combustion gas scouring capability is strong.
The technical solution of the utility model is to comprise turbine outer shroud matrix and prismatic metal grill, it is characterized in that: described prismatic metal grill is fixed on the turbine outer shroud matrix inner edge; Be filled with powder filler in the described prismatic metal grill, powder filler, prismatic metal grill and turbine outer shroud matrix are integral admittedly behind the high temperature sintering.
The utility model has the advantages that simple in structurely, make easily that wear-resisting, coating is not fallen piece, do not come off, anti-combustion gas scouring capability is strong, safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure 1, turbine outer shroud matrix, 2, the prismatic metal grill, 3, powder filler.
Embodiment
As seen from Figure 1, the utility model is made up of turbine outer shroud matrix 1 and prismatic metal grill 2.With high temperature vacuum brazing prismatic metal grill 2 is welded on turbine outer shroud matrix 1 inner edge, is filled with Ni-Al powder filler 3 in the prismatic metal grill 2, the thickness of Ni-Al powder filler 3 is 2/3 of prismatic metal grill 2 volumes.
Adopt high temperature sintering that Ni-Al powder filler 3, prismatic metal grill 2 and turbine outer shroud matrix 1 are integral admittedly.
Claims (1)
