Definitions
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the pawn prefferably has a non circular and be adjusted in a piercing having a corresponding non-circular section.
- 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.
- 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.
- 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.
- FIG. 3 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.
- 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.
- 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.
