Definitions
- the subject of this invention is a device for stopping in rotation a sector bearing vanes fixed in a shell forming part of a casing of a turbomachine.
- the ferrules of the turbomachines are generally composed of two complementary sectors each extending over a half-turn and which are provided with a continuous circular rabbet for receiving stator sectors carrying fixed vanes and which extend over portions of circumference smaller.
- This device as such leaves the sectors free to slide in the ferrule sliding together in the rabbet, which produces wear and noise during operation.
- it is planned to add a rotation stop system for these sectors, which has already taken various forms in the known devices. It is first possible to place bars crossing the rabbets between the ferrule sectors, so as to stop the movement of the rectifier sectors.
- This system is simple but has the disadvantage that it can not install more than two stop means in rotation: it therefore only partially remedies the anarchic movement of the blade sectors.
- the invention relates to a rotation stop system of a very simple nature and which can equip at a lower cost an already existing machine that has the desire to improve.
- This system applies individually to the rectifier sectors and thus ensures total immobility of the sectors if it is provided on each of them, without requiring excessive costs.
- Another advantage of the invention is that the seal between the rectifier sectors is not compromised.
- the rotational stop device comprises a pair of bores operated in extension in a rectifier sector and the shell respectively, as well as a pin engaged in the bores and means for holding the pin in the bores. holes.
- the holes may in particular be operated through a rim of the rectifier sector and through a rabbet of the ferrule in which the rim is depressed.
- the holding means then advantageously comprise a rod engaged under the rim in the rabbet and occupying a recess intersecting the pin; they may also include a tongue protruding from the pawn and abutting against the rectifier sector on one side, the ferrule on the other side.
- the pin has a non-circular section and is fitted into a bore having a corresponding non-circular section.
- FIG. 1 shows a portion of a ferrule 15 and a rectifier sector 16; the latter comprises an edge 17 directed in an axial direction engaged in a rebate 18 formed between a hook portion 19, bent in the other axial direction, and a cylindrical main portion 20 of the shell 15.
- the shell 15 comprises a bore 21 passing through the hook portion 19, and the sector member 16 also includes a bore 22 intersecting the flange 17 and extending the bore 21; Figure 4 helps to better grasp the layout.
- a pin 23 also seen in Figure 2 is engaged in the holes 21 and 22 and thus ensures the rotation stop sector 16 relative to the shell 15. It is retained in the holes 21 and 22 by a fastening ring 24 engaged at the bottom of the rabbet 18, under the rim 17, from a not shown orifice operated in the hook portion 19, and which passes through a recess 25 of the pin 23.
- the accidental extraction of the pin 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 rectifier sector 16. This can be accomplished by joining the rectifier sector 16 to the ferrule after having put the pin 23 in place in the holes 21 and 22.
- the ferrule 15 is joined to another ferrule 27 which is radially internal to it, the bore 21 opens on the lower side on the other ferrule 27, and the tongue 26 abuts against the Another ferrule 27, which does not change anything, however.
- the ring 24 is then slid to the bottom of the rabbet 18; it can extend in front of a series of rectifier sectors 16 and retain as many counters 23.
- FIG. 3 Another embodiment, whose implantation is also shown in Figure 4, appears in Figure 3 and comprises a pin 30 comprising a pair of side projections 31.
- the pin 30 is, like the previous one, engaged in a hole 32 operated in a rim 33 of a rectifier sector 34, as well as in a bore 35 extending the former and operated here through the other ferrule 27.
- the counter 30 When the other ferrule 27 and the rectifier sector 34 are assembled, the counter 30 having previously been engaged in the holes 32 and 35, they include a cavity 36 occupied by the projections 31 by preventing the pin 30 is extracted. This is the same mounting mode for the pins 23 and 30.
- the pins 23 and 30 have non-circular portions such as plane facets 37 and 38, engaged in one of the holes 21, 22, 32 and 35 to prevent accidental rotation of the pin 23 or 30 which would interfere with the assembly. ; the holes in which these non-circular portions are engaged obviously have a section of complementary shape.
- the ends of the pins can be tapered to facilitate their insertions in the holes; one of them bears the reference 39 for the pawn 30; it is shaped like a pyramid.
