Description
Technical field
The application belongs to aero-engine stator blade mounting structure design field, in particular to a kind of stator blade installation
Structure.
Background technique
There are following at least two outstanding problems for existing assembled stator blade structure:
1) there is threaded radial cylinder boss on stator blade supramarginal plate, cylinder boss is stretched out by the hole above casing
Casing tightens nut to fixed stator blade outside casing, and this mounting means radial height is high, seriously affects gabarit, and
Structure bulky, heavier-weight；
2) when installing, first stator blade to be fixed on casing, then inner ring is installed, inner ring is divided into two sections of front and back, passes through
Pin and axial bolts connection, structure is complicated, it is difficult to install.
Thus, it is desirable to have a kind of technical solution overcomes or at least mitigates at least one drawbacks described above of the prior art.
Utility model content
At least one in order to solve the above-mentioned technical problem, this application provides a kind of stator blade mounting structures.
This application discloses a kind of stator blade mounting structures, for stator blade to be mounted between casing and inner ring,
The stator blade includes blade and the supramarginal plate and inframarginal that blade length direction both ends end is fixedly installed, in institute
The bottom setting for stating inframarginal is having threaded radial cylinder boss, and corresponding position, which is provided with, in the inner ring is adapted
Through-hole, it is described radial direction cylinder boss be mounted in the through-hole by nut；
The radial outer side of the supramarginal plate is arranged to shape compatible with the casing inner ring surface.
According at least one embodiment of the application, the stator blade mounting structure further include:
Threaded hole, the threaded hole radially sequentially pass through the casing and the supramarginal plate；
Stud, the stud interference fit are arranged in the threaded hole.
According at least one embodiment of the application, the nut is self-locking nut.
At least there are following advantageous effects in the application:
The stator blade mounting structure of the application, the radial cylinder boss of stator blade inframarginal are mounted on interior by nut
In the through-hole of ring, so that it is easier for installation, also, cancel the radial boss outside stator blade supramarginal plate, reduce radial height
Degree reduces contour dimension and mitigates weight, also improves assembly efficiency.

In explanation the application, and it should not be understood as the limitation to the application.Based on the embodiment in the application, ordinary skill people
Member's every other embodiment obtained without creative efforts, shall fall in the protection scope of this application.Under
Face is described in detail embodiments herein in conjunction with attached drawing.
In the description of the present application, it is to be understood that term " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or positional relationship of the instructions such as "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside" is based on attached drawing institute
The orientation or positional relationship shown is merely for convenience of description the application and simplifies description, rather than the dress of indication or suggestion meaning
It sets or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as protecting the application
The limitation of range.
1 to Fig. 2 the application stator blade mounting structure is described in further details with reference to the accompanying drawing.
This application discloses a kind of stator blade mounting structure, for by stator blade be mounted on casing 21 and inner ring 22 it
Between；Wherein, stator blade may include blade 11 and 12 He of supramarginal plate that 11 length direction both ends end of blade is fixedly installed
Inframarginal 13.
In the stator blade mounting structure of the application, in the bottom of inframarginal 13, setting is having threaded radial cylinder convex
Platform 131, corresponding position is provided with compatible through-hole in inner ring 22, and radial cylinder boss 131 is mounted on by nut 132
In through-hole；Further, in this embodiment preferably nut 132 is self-locking nut.
In addition, the radial outer side of supramarginal plate 12 is arranged to shape compatible with 21 inner ring surface of casing.
Further, the stator blade mounting structure of the application can also include threaded hole 3 and stud；Threaded hole 3 is along diameter
To casing 21 and supramarginal plate 12 is sequentially passed through, stud interference fit is arranged in threaded hole 3.
The stator blade mounting structure of the application to improve assembly efficiency, and reduces contour dimension, as shown in Figure 1 and Figure 2,
Stator blade is first passed through into through-hole uniformly distributed above inner ring 22 by the threaded radial cylinder boss 131 of inframarginal 13, is led to
It crosses self-locking nut and fixes (such as Fig. 1)；Whole circle stator blade is successively installed；Stator blade supramarginal plate 12 is mutually held out against by repair,
The whole circle sub-assembly of stator blade (i.e. inner ring 22 and the sub-assembly of the whole circle stator blade installed thereon formation) is formed, to stator leaf
The whole circle sub-assembly supramarginal plate Combined machining turning of piece (such as Fig. 2 diameter B) equidimension；Then the whole circle sub-assembly of stator blade is pacified
Casing 21 is put into, Fig. 2 structure is formed, recombinant processes interference threaded hole 3 (Fig. 2 hole A)；Band interference spiral shell is screwed into threaded hole 3
The stud of line, reconditioning pipes' analysis, backlash point prevent stud from screwing out.
The stator blade mounting structure of the application cancels the radial boss outside stator blade supramarginal plate, reduces radial height
Degree reduces contour dimension and mitigates weight；In addition, the stator blade mounting structure of the application improves assembly efficiency, and stator leaf
Piece supramarginal plate Combined machining forms, and reduces the workload of single stator blade processing, reduces cost.
The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any
Within the technical scope of the present application, any changes or substitutions that can be easily thought of by those familiar with the art, all answers
Cover within the scope of protection of this application.Therefore, the protection scope of the application should be with the scope of protection of the claims
It is quasi-.
