Abstract

The rotational stop assembly has the sectors of the flow aligner guide vanes retained against tangential rotational and sliding movements in the leaves of the shroud by stop pins (30). These extend through bores (32) in extensions of the components. The pins are retained by flexible joints or tongues (31).

Description

Le sujet de cette invention est un dispositif d'arrêt en rotation d'un secteur porteur d'aubes fixes dans une virole faisant partie d'un carter d'une turbomachine.The subject of this invention is a device stopping a rotating sector with fixed vanes in a ferrule forming part of a housing of a turbine engine.

Les viroles des turbomachines sont généralement composées de deux secteurs complémentaires s'étendant chacun sur un demi-tour et qui sont munis d'une feuillure circulaire continue pour recevoir des secteurs de redresseur porteurs d'aubes fixes et qui s'étendent sur des portions de circonférence plus petites. Ce dispositif tel quel laisse les secteurs libres de coulisser dans la virole en glissant ensemble dans la feuillure, ce qui produit de l'usure et du bruit pendant le fonctionnement. C'est pourquoi on prévoit d'ajouter un système d'arrêt en rotation de ces secteurs, qui a déjà pris diverses formes dans les dispositifs connus. Il est d'abord possible de placer des barrettes croisant les feuillures entre les secteurs de virole, de façon à arrêter le mouvement des secteurs de redresseur. Ce système est simple mais présente l'inconvénient qu'on ne peut pas installer plus de deux moyens d'arrêt en rotation : il ne remédie donc que partiellement au mouvement anarchique des secteurs d'aubes.The ferrules of the turbomachines are generally composed of two complementary sectors extending each on a half turn and which are provided with a circular rebate continues to receive sectors of stator with fixed vanes and which extend over more circumference portions small. This device as it is leaves the sectors free to slide in the ferrule while sliding together in the rabbet, which produces wear and tear noise during operation. That's why we plans to add a rotational shutdown system to these sectors, which has already taken various forms in known devices. It is first possible to place bars crossing the rabbets between the ferrule sectors, so as to stop the movement of rectifier sectors. This system is simple but has the disadvantage that you can not install more than two means of stopping in rotation: it does not cure therefore only partially to the anarchic movement of sectors of blades.

On a encore prévu de lier individuellement les secteurs d'aubes à un carter extérieur par des tiges d'extension radiale, mais il est évident qu'une telle construction complique beaucoup la machine. It was further planned to link individual blade sectors to an outer casing by rods radial extension, but it is obvious that such construction greatly complicates the machine.

L'invention a pour objet un système d'arrêt en rotation de nature très simple et qui puisse équiper à moindre coût une machine déjà existante qu'on a le désir de perfectionner. Ce système s'applique individuellement aux secteurs de redresseur et assure donc une immobilité totale des secteurs s'il est prévu sur chacun d'eux, sans nécessiter de frais excessifs. Un autre avantage de l'invention est que l'étanchéité entre les secteurs de redresseur n'est pas compromise.The subject of the invention is a stop system in rotation of very simple nature and which can equip to lower cost an already existing machine that we have the desire to perfect. This system applies individually to the rectifier sectors and ensures therefore a total immobility of the sectors if it is planned on each of them, without requiring excessive costs. Another advantage of the invention is that the seal between the rectifier sectors is not compromised.

Sous sa forme la plus générale, le dispositif d'arrêt en rotation comprend une paire de perçages opérés en prolongement dans un secteur de redresseur et la virole respectivement, ainsi qu'un pion engagé dans les perçages et des moyens de maintien du pion dans les perçages.In its most general form, the device stopper includes a pair of holes operated in extension in a rectifier area and the ferrule respectively, as well as a pawn engaged in the holes and means of maintaining the pawn in the holes.

Les perçages peuvent notamment être opérés à travers un rebord du secteur de redresseur et à travers une feuillure de la virole dans laquelle le rebord est enfoncé.The holes may in particular be operated at across a rim of the rectifier sector and across a rebate of the ferrule in which the rim is pressed.

Les moyens de maintien comprennent alors avantageusement un jonc engagé sous le rebord dans la feuillure et occupant un évidement coupant le pion ; ils peuvent aussi comprendre une languette saillant du pion et venant buter contre le secteur de redresseur d'un côté, la virole de l'autre côté.The holding means then comprise advantageously a ring engaged under the rim in the rabbet and occupying a recess intersecting the pawn; they may also include a protruding tongue of pawn and abutting against the rectifier sector on one side, the ferrule on the other side.

Il est avantageux que le pion ait une section non circulaire et soit ajusté dans un perçage ayant une section non circulaire correspondante.It is advantageous for the pawn to have a non circular and be adjusted in a piercing having a corresponding non-circular section.

L'invention sera maintenant décrite en référence aux figures dont :

  • la figure 1 est une vue d'une réalisation particulière de l'invention,
  • la figure 2 représente le pion isolément,
  • la figure 3 est une vue d'une deuxième réalisation de l'invention, et
  • la figure 4 illustre la disposition de l'invention dans la machine.
The invention will now be described with reference to the figures of which:
  • FIG. 1 is a view of a particular embodiment of the invention,
  • FIG. 2 represents the pion in isolation,
  • FIG. 3 is a view of a second embodiment of the invention, and
  • Figure 4 illustrates the arrangement of the invention in the machine.

On a représenté à la figure 1 une portion d'une virole 15 et d'un secteur de redresseur 16 ; ce dernier comprend un rebord 17 dirigé dans un sens axial engagé dans une feuillure 18 réalisée entre une portion en crochet 19, courbée dans l'autre sens axial, et une portion principale 20 cylindrique de la virole 15. La virole 15 comprend un perçage 21 traversant la portion de crochet 19, et l'élément de secteur 16 comprend aussi un perçage 22 coupant le rebord 17 et prolongeant le perçage 21 ; la figure 4 aide à mieux saisir la disposition.FIG. 1 shows a portion of a ferrule 15 and a rectifier sector 16; this last comprises a ledge 17 directed in an axial direction engaged in a rabbet 18 made between a portion hook 19, bent in the other axial direction, and a cylindrical main portion 20 of the shell 15. The ferrule 15 includes a piercing 21 through the portion hook 19, and the sector element 16 comprises also a bore 22 cutting the flange 17 and extending piercing 21; Figure 4 helps to better understand the disposition.

Un pion 23 vu aussi à la figure 2 est engagé dans les perçages 21 et 22 et assure donc l'arrêt en rotation du secteur 16 par rapport à la virole 15. Il est retenu dans les perçages 21 et 22 par un jonc de fixation 24 engagé au fond de la feuillure 18, sous le rebord 17, à partir d'un orifice non représenté opéré dans la partie en crochet 19, et qui traverse un évidement 25 du pion 23. L'extraction accidentelle du pion 23 peut encore être empêchée par une languette 26 saillant du pion 23 et butant d'un côté contre la virole et de l'autre côté contre un secteur de redresseur 16. Cela peut être accompli en joignant le secteur de redresseur 16 à la virole après avoir mis le pion 23 en place dans les perçages 21 et 22. La virole 15 est jointe à une autre virole 27 qui lui est radialement interne, le perçage 21 s'ouvre du côté inférieur sur l'autre virole 27, et la languette 26 bute contre l'autre virole 27, ce qui ne change cependant rien.A pawn 23 also seen in Figure 2 is engaged in holes 21 and 22 and thus ensures the stop in rotation of the sector 16 relative to the ferrule 15. It is retained in the holes 21 and 22 by a ring of fastening 24 engaged at the bottom of the rabbet 18, under the flange 17, from an orifice not shown operated in the hook part 19, and running through a recess 25 of the pawn 23. The accidental extraction of the pawn 23 can still be prevented by a tongue 26 protruding from the pin 23 and abutting on one side against the ferrule and on the other side against a sector of 16. This can be accomplished by joining the rectifier sector 16 to the ferrule after putting the peg 23 in place in holes 21 and 22. The ferrule 15 is attached to another shell which is radially internal, the bore 21 opens on the side lower on the other ferrule 27, and the tongue 26 against the other ferrule 27, which does not change however nothing.

Le jonc 24 est ensuite glissé au fond de la feuillure 18 ; il peut s'étendre devant une série de secteurs de redresseur 16 et retenir autant de pions 23.The ring 24 is then slid to the bottom of the rebate 18; it can expand in front of a series of rectifier sectors 16 and retain as many pawns 23.

Un autre mode de réalisation, dont l'implantation est aussi représentée à la figure 4, apparaít à la figure 3 et comprend un pion 30 comprenant une paire de saillies latérales 31. Le pion 30 est, comme le précédent, engagé dans un perçage 32 opéré dans un rebord 33 d'un secteur de redresseur 34, ainsi que dans un perçage 35 prolongeant le précédent et opéré ici à travers l'autre virole 27. Quand l'autre virole 27 et le secteur de redresseur 34 sont assemblés, le pion 30 ayant été auparavant engagé dans les perçages 32 et 35, ils englobent une cavité 36 qu'occupent les saillies 31 en empêchant que le pion 30 ne soit extrait. On procède donc au même mode de montage pour les pions 23 et 30.Another embodiment, including the implantation is also shown in Figure 4, appears on the FIG. 3 and comprises a pin 30 comprising a pair of Lateral projections 31. The pawn 30 is, like the previous, engaged in a 32 borehole operated in a flange 33 of a rectifier sector 34, as well as in a piercing 35 extending the previous and operated here to through the other ferrule 27. When the other ferrule 27 and the rectifier sector 34 are assembled, the pawn 30 having previously been engaged in holes 32 and 35, they include a cavity 36 occupied by the projections 31 by preventing the pin 30 from being extracted. We proceed therefore the same mounting mode for the pins 23 and 30.

Les pions 23 et 30 présentent des portions non circulaires telles que des facettes planes 37 et 38, engagées dans l'un des perçages 21, 22, 32 et 35 afin d'interdire une rotation accidentelle du pion 23 ou 30 qui gênerait l'assemblage ; les perçages dans lesquels ces portions non circulaires sont engagées ont évidemment une section de forme complémentaire. Les extrémités des pions peuvent être effilées pour faciliter leurs insertions dans les perçages ; l'une d'elles porte la référence 39 pour le pion 30 ; elle est en forme de pyramide .The pieces 23 and 30 have portions such as flat facets 37 and 38, engaged in one of the holes 21, 22, 32 and 35 so to prohibit accidental rotation of pawn 23 or 30 which would hinder the assembly; the holes in which these non-circular portions are engaged have obviously a section of complementary shape. The ends of the pins can be tapered for facilitate their insertions in the holes; Moon of them bears the reference 39 for the pawn 30; she is in the shape of a pyramid.

Il est clair que d'autres modes de réalisation sont possibles, ne fût-ce qu'en combinant certains des éléments décrits sur les deux modes de réalisation complètement décrits ici.It is clear that other embodiments are possible, if only by combining some of the elements described in both embodiments completely described here.
