Description
Technical field
The invention belongs to field of electromechanical technology, more particularly, to a kind of nozzle ring of anti-hot tearing.
Background technique
The working environment of nozzle ring is severe, and temperature is high, and high/low temperature stress is big, also acts as the work of support surrounding components
With being easy to happen hot tearing.According to actual use situation, the position that hot tearing occurs for nozzle ring is often inner ring, how to be reduced
The hot tearing failure of nozzle ring, improves its reliability, is the core technology of nozzle ring design.
Summary of the invention
In view of this, the present invention is directed to propose a kind of nozzle ring of anti-hot tearing, meet support stress in the case where,
Thermal stress is reduced, hot tearing risk is reduced.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of nozzle ring of anti-hot tearing, including ontology, the ontology include outer ring, blade and inner ring, further include branch
Support and elastic ring, support frame as described above include the horizontal connection structure of cylinder-like structure and its inside, the bottom of cylinder-like structure
Elasticity platform with outward extension, the elasticity platform upper surface are equipped with axial destressing slot, and horizontal connection structure is tied with cylindric
The junction of structure is equipped with support destressing slot；
Two end faces of the inner ring are located upstream face and downstream location face respectively, and support frame as described above insertion is described interior
Circle is in close contact the downstream location face and the elastic platform；The elasticity ring set is on the cylinder-like structure, bottom
End face and the located upstream face are in close contact；Support frame as described above is fixedly connected with the elastic ring.
Further, there are equally distributed several upstream retraction slots and equally distributed several contracted downstreams on the inner ring
The position relative misalignment certain angle of slot, the upstream retraction slot and the contracted downstream slot.
Further, there are several slots, and slotting position relative misalignment in the inner and outer of shown elastic ring, and inside is opened
Equally distributed non-through slot is opened in the through slot of even distribution, outside.
Compared with the existing technology, present invention has the advantage that
(1) present invention is shifted the axially loaded of nozzle ring by the composite structure of inner ring, support frame, elastic ring
There are axial destressing slot and support destressing slot onto support frame, on support frame, meets the force request of nozzle ring；
(2) inner ring and elastic ring of the present invention have the notching construction for preventing thermal stress, and inner ring and elastic ring can independently be held
By radial deformation, without to supporting framework at stress influence, it is therefore prevented that hot tearing.

Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
A kind of nozzle ring of anti-hot tearing, as shown in Fig. 1 to 7, including ontology 1, the ontology 1 include outer ring 2, blade
3 and inner ring 4, it is integrated hot investment casting；It further include support frame 9 and elastic ring 13,
Support frame as described above 9 includes the horizontal connection structure of cylinder-like structure and its inside, and the bottom of cylinder-like structure is equipped with
Outwardly extending elastic platform 10, elasticity 10 upper surface of platform are equipped with axial destressing slot 11, horizontal connection structure and cylindrical shape
The junction of structure is equipped with support destressing slot 12；
Two end faces of the inner ring 4 are located upstream face 8 and downstream location face 7 respectively, and support frame as described above 9 is inserted into described
Inner ring 4 is in close contact the downstream location face 7 with the elastic platform 10；13 sets of the elastic ring is in the cylinder-like structure
On, bottom end face and the located upstream face 8 are in close contact；Support frame as described above 9 is fixedly connected with the elastic ring 13.
The inner ring 4 has an equally distributed 6 upstream retraction slots 6 and equally distributed 6 contracted downstream slots 5, it is described on
30 ° of position relative misalignment for swimming retraction slot 6 and the contracted downstream slot 5.
The elastic ring 13 is that an inner and outer has large number of slot, and the circle of slotting position relative misalignment
Ring.Open 18 equally distributed through slots, the width 3mm of slot in inside.18 equally distributed non-through slots 15 are opened in outside, non-to pass through
The width 3mm slot of through slot.
Assembling process of the present invention is as follows:
