Abstract
The invention provides a ribbed sealing ring. The ribbed sealing ring comprises a sealing ring body and a clogging block matched with the sealing ring body. A ribbed air guide plate is arranged on the sealing ring body. An edge curl part is formed at the free end of the ribbed air guide plate. According to the ribbed sealing ring, the problem that a ribbed sealing ring is prone to a short service life due to vibration in the prior art is effectively solved.
Description
Technical field
The present invention relates to whirlpool paddle type technical field of engines, to obturage circle in particular to a kind of rib shape.
Background technique
In the paddle type motor of whirlpool, rib shape is obturaged and enclosed Main Function is the cooling blast that before reasonably guiding the 1st grade of turbine disk, comb tooth place flows out, cooling turbine dish and blade tenon effectively.Rib shape obturage circle concrete structure as shown in Figure 1, rib shape obturage circle comprise rib shape wind deflector 10 ', sprue 20 ' and ring 30 ' of obturaging composition.
Motor in the course of the work, can produce vibration.Enclose similar cantilever structure because rib shape is obturaged, it is fixed end that ring 30 ' of obturaging is fixed in Roller Shaft bearing, and rib shape wind deflector 10 ' is cantilever free end.Character according to cantilever: cantilever is longer, the amount of deflection of rib shape wind deflector 10 ' is larger, and when vibrating, amplitude is larger, and then the vibration stress produced is larger.In long-term work, rib shape circle of obturaging can be made to produce tired, cause rib shape obturage circle rib shape wind deflector 10 ' edge breaks, fall the damages such as block, affect the normal use of motor.
Summary of the invention
Main purpose of the present invention is to provide a kind of rib shape to obturage circle, to obturage the problem of service life reduction that circle easily causes because of vibration to solve prior art middle rib shape.
To achieve these goals, the invention provides a kind of rib shape and to obturage circle, comprise obturage ring and the sprue that matches with ring of obturaging, ring of obturaging is provided with rib shape wind deflector, the free end of rib shape wind deflector forms flanging part.
Further, be provided with stiffening ring in flanging part, flanging part wraps stiffening ring.
Further, stiffening ring is steel wire.
Further, the outside dimension of rib shape wind deflector is in the scope of 405mm to 410mm.
Further, the outside dimension of rib shape wind deflector is 408mm.
Further, obturage between ring and sprue and be provided with Sealing.
Further, Sealing is graphite block.
Apply technological scheme of the present invention, the flanging part of the free end formation of rib shape wind deflector strengthens the rigidity of rib shape wind deflector outer rim effectively, stops the generation in the tired source of rib shape wind deflector outer rim.
Except object described above, feature and advantage, the present invention also has other object, feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
Accompanying drawing explanation
The Figure of description forming a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 show rib shape of the prior art obturage circle structural representation; And
Fig. 2 shows rib shape according to the present invention and to obturage the structural representation of embodiment of circle.
Wherein, above-mentioned accompanying drawing comprises the following drawings mark:
10, to obturage ring; 20, sprue; 30, rib shape wind deflector; 31, flanging part; 40, stiffening ring; 50, graphite block.
Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
The present invention program is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the embodiment of a part of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, should belong to the scope of protection of the invention.
The rib shape that Fig. 2 shows the present embodiment is obturaged circle, and this rib shape circle of obturaging comprises obturage ring 10 and the sprue 20 that matches with ring 10 of obturaging, and ring 10 of obturaging is provided with rib shape wind deflector 30, the free end of rib shape wind deflector 30 forms flanging part 31.
The flanging part 31 of the free end formation of rib shape wind deflector 30 strengthens the rigidity of rib shape wind deflector 30 outer rim effectively, stops the generation in the tired source of rib shape wind deflector 30 outer rim.
As shown in Figure 2, in the present embodiment, be provided with stiffening ring 40 in flanging part 31, flanging part 31 wraps stiffening ring 40.Stiffening ring 40 strengthens the rigidity of rib shape wind deflector 30 outer rim further, adds the working life of rib shape wind deflector 30.Preferably, stiffening ring 40 is steel wire.
The outside dimension of rib shape wind deflector 30 is in the past φ 419mm, and in the process of engine vibration, the vibrations be easy to along with motor are resonated.In the present embodiment, the outside dimension of rib shape wind deflector 30 is in the scope of 405mm to 410mm.Low in the single order vibration ratio prior art of the rib shape wind deflector 30 after improvement, avoid produce resonance frequency, fundamentally improve rib shape obturage circle vibration characteristics, improve working life.Preferably, the outside dimension of rib shape wind deflector 30 is 408mm.
As shown in Figure 2, obturage between ring 10 and sprue 20 and be provided with lubrication part.Like this, the gap of obturaging between ring 10 and sprue 20 can effectively be sealed.Preferably, lubricating 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.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
