Abstract
The invention provides a kind of ribbed to obturage circle, including ring and the sprue that matches with ring of obturaging obturaged, ring of obturaging is provided with ribbed wind deflector, the free end formation flanging part of ribbed wind deflector.Technical scheme efficiently solves ribbed in prior art and obturages the problem of service life reduction that circle easily causes because of vibration.
Description
Technical field
The present invention relates to whirlpool paddle type technical field of engines, obturage circle in particular to a kind of ribbed.
Background technology
In turbogenerator, often use deflector so that air-flow to be cooled down, water conservancy diversion and obturaging, such as Patent No.:
CN202266301U (turbine and the turbogenerator with this turbine) and CN103883362A (has sealing leak stream
The turbine apparatus of diversion function) and Publication No.: CN101178029A (interstage cooled turbine engine).Especially, exist
In the paddle type electromotor of whirlpool, (ribbed is close for circle to use the ribbed wind deflector 10 ' of ribbed to obturage with sprue 20 ' and ring 30 ' of obturaging composition ribbed
Seal concrete structure is as shown in Figure 1), in order to the cooling air-flow flowed out at comb tooth before reasonably guiding the 1st grade of turbine disk, and effectively
The ground cooling turbine disk and blade tenon.
Electromotor in the course of the work, can produce vibration.Obturaging due to ribbed and enclose similar cantilever design, ring 30 ' of obturaging is fixed on
Being fixing end in Roller Shaft bearing, ribbed wind deflector 10 ' is cantilever free end.Character according to cantilever: cantilever is the longest,
The amount of deflection of ribbed wind deflector 10 ' is the biggest, and when vibration, amplitude is the biggest, and then the vibration stress produced is the biggest.In long-term work
In, ribbed circle of obturaging can be made to produce fatigue, cause ribbed obturage circle ribbed wind deflector 10 ' edge breaks, fall block etc. and damage,
Affect the normal use of electromotor.
Summary of the invention
Present invention is primarily targeted at a kind of ribbed of offer to obturage circle, obturage circle easily because vibrating solving ribbed in prior art
And the problem of the service life reduction caused.
To achieve these goals, the invention provides a kind of ribbed and obturage circle, including ring and the blocking up of matching with ring of obturaging of obturaging
Block, ring of obturaging is provided with ribbed wind deflector, and the free end of ribbed wind deflector forms flanging part.
Further, being provided with stiffening ring in flanging part, flanging part wraps stiffening ring.
Further, stiffening ring is steel wire.
Further, the outside dimension of ribbed wind deflector is in the range of 405mm to 410mm.
Further, the outside dimension of ribbed wind deflector is 408mm.
Further, obturage and between ring and sprue, be provided with sealing member.
Further, sealing member is graphite block.
Application technical scheme, the flanging part that the free end of ribbed wind deflector is formed strengthens outside ribbed wind deflector effectively
The rigidity of edge, stops the generation in ribbed wind deflector outer rim fatigue source.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.Below
Will be with reference to figure, the present invention is further detailed explanation.
Accompanying drawing explanation
The Figure of description of the part constituting the present invention is used for providing a further understanding of the present invention, and the present invention's is schematic real
Execute example and illustrate for explaining the present invention, being not intended that inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 show ribbed of the prior art obturage circle structural representation；And
Fig. 2 shows that the ribbed according to the present invention is obturaged the structural representation of embodiment of circle.
Wherein, above-mentioned accompanying drawing includes the following drawings labelling:
10, obturage ring；20, sprue；30, ribbed wind deflector；31, flanging part；40, stiffening ring；50, graphite block.
Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the present invention and the feature in embodiment can be mutually combined.
Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
In order to make those skilled in the art be more fully understood that the present invention program, below in conjunction with the accompanying drawing in the embodiment of the present invention,
Technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only the present invention
The embodiment of a part rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not having
Have and make the every other embodiment obtained under creative work premise, all should belong to the scope of protection of the invention.
Fig. 2 shows that the ribbed of the present embodiment is obturaged circle, and this ribbed circle of obturaging includes obturaging ring 10 and matching with ring 10 of obturaging
Sprue 20, ring 10 of obturaging is provided with ribbed wind deflector 30, and the free end of ribbed wind deflector 30 forms flanging part 31.
The flanging part 31 that the free end of ribbed wind deflector 30 is formed strengthens the rigidity of ribbed wind deflector 30 outer rim effectively, stops
The generation in ribbed wind deflector 30 outer rim fatigue source.
As in figure 2 it is shown, in the present embodiment, being provided with stiffening ring 40 in flanging part 31, flanging part 31 wraps stiffening ring 40.
Stiffening ring 40 strengthens the rigidity of ribbed wind deflector 30 outer rim further, adds the service life of ribbed wind deflector 30.Excellent
Selection of land, stiffening ring 40 is steel wire.
The outside dimension of conventional ribbed wind deflector 30 is φ 419mm, is easy to along with electromotor during engine vibration
Vibrations resonate.In the present embodiment, the outside dimension of ribbed wind deflector 30 is in the range of 405mm to 410mm.
In the single order vibration ratio prior art of the ribbed wind deflector 30 after improvement low, avoid produce resonance frequency, from all
On improve ribbed obturage circle vibration characteristics, improve service life.Preferably, the outside dimension of ribbed wind deflector 30 is
408mm。
Lubrication part it is provided with between ring 10 and sprue 20 as in figure 2 it is shown, obturage.As such, it is possible to effectively seal against ring 10 of obturaging
And the gap between sprue 20.Preferably, lubrication part is graphite block 50.
These are only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art,
The present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of being made, equivalent,
