Definitions
- the invention presented here concerns the high pressure turbine of a turbomachine such as a turbojet engine used on an airplane. It concerns more precisely a sectorized fixed rectifier for a turbomachine compressor.
- US-A-4,126,405 discloses a segmented mounting of a turbine distributor.
- Document FR-A-2 728 015 discloses a stator distributor of a turbine comprising sectors each consisting of an inner segment and an outer segment connected by blades.
- a housing integrated in the stator of the compressor is intended to support the butted areas to each other. of the anti-rotation means are provided to prevent the rotation of the sectors supported by the housing.
- the present invention has been designed to to further improve the manufacture and cost of a fixed rectifier for turbomachine compressor.
- the housing is made in two parts or more, this which facilitates the manufacture.
- the parts of the housing and the rectifier sectors are associated by a system forming slide and slide.
- Anti-rotation means are designed to prevent the rotation of sectors relative to the crankcase.
- the housing is made of two parts in the shape of a semicircle.
- the casing comprising two radial flanks being face
- the slide means comprises two Opposite grooves made in flanks, edges external segments of the sectors constituting the slider means.
- the anti-rotation means fixed to the planes of joint can then include at least one bar immobilized between the two grooves by said means fastening and forming a stop for a sliding sector in a casing slide.
- This bar can be a pair of tweezers inserted by bringing the two branches together in dwellings of intended reception in the throats, and immobilized in these dwellings by loosening of the two branches, thus realizing said fixing means.
- Ways anti-rotation attached to the joint planes can also include at least one anti-rotation lock constituted by an element comprising slide means adapted to the slider means of the parts of the carter, the element also comprising means immobilization on the crankcase.
- These means immobilization can be of the tenon-mortise type, a tenon engaging in a mortise when the element is pushed in a direction perpendicular to the sliding direction of the element in the housing, thus realizing said fixing means.
- the segment outside the sector adjacent to that element may have one of its ends that has a clearance so that, when this adjacent sector is slipped on contact said element, the element can be pushed into said perpendicular direction.
- the anti-rotation means blocked on the parts of the housing may then comprise at least one anti-rotation lock constituted by an element comprising slide means adapted to means forming a slide of the parts of the casing, the element also comprising means immobilization on the crankcase.
- These means immobilization can be of the tenon-mortise type, a tenon engaging in a mortise when the element is pushed in a direction perpendicular to the sliding direction of the element in the housing, thereby realizing said locking means.
- the segment outside a sector adjacent to that element may have one of its ends that presents a clearance so that when this adjacent area is slipped into contact with said element, the element can be pushed in said perpendicular direction.
- Figure 1 is a partial sectional view of a compressor of a turbomachine using sectorized fixed rectifiers 1, 2 and 3 according to the invention. These rectifiers are functionally identical.
- the rectifier 1 will be described more precisely. It includes a built-in circular case 4 in the stator of the compressor and supporting sectors such as sector 5.
- a sector 5 consists of a segment inside 7 and an outer segment 6 connected between they by blades 8.
- Figure 2 is a partial view and exploded sectorized fixed rectifier 1. It includes example a housing in two parts in the form of a semicircle. Figure 2 shows partially one of the parts 11 of this case with one of his joint plans 12 intended to be fixed on a joint plane corresponding to the other part of the housing. Three sectors 5 being assembled are represented. For sector 5, we recognize the outer segment 6, the inner segment 7 and the blades 8 which connect them.
- the housing portion 11 comprises two flanks radial 12 and 13 facing each other and each provided of a throat.
- the throats are located vis-à-vis constitute a slide.
- the edges 21 and 22 of the segment outside 6 of sector 5 protrude outwards to ensure a slide function with respect to the slide formed by the casing portion 11.
- an anti-rotation lock is installed at the joint plane 12 of the housing part 11. It can be a bar or a lock such as the one shown in Figure 4.
- Figure 2 also shows an anti-rotation lock 30 disposed between two sectors 5.
- This latch 30 is shown in cavalier view in Figure 3. It is formed an element 31 which is placed between the two flanks 12 and 13 of the housing portion 11 (see Figure 2).
- the element 31 is in the shape of an arc of a circle and extended by an outer edge 32 and an inner edge 33.
- the edges 32 and 33 are provided so that the lock 30 can slide in the grooves of the part of casing 11.
- the outer edge 32 has a lug 34 protruding from the plane of the element 31. It is even for the lug 35 of the inner edge 33.
- Figures 5 and 6 illustrate two steps of setting up an anti-rotation lock 30 between two sectors. 5.
- a only flanks of the housing portion 11 has been represent. We can see the gorge 14 provided in this flank.
- Figure 5 shows a first sector 5 already installed (to the left of the figure) and a second Sector 5 being installed (on the right of the figure). Between these two sectors was introduced by sliding a latch 30. Note that the height of the groove 14 allows the passage of the outer edge of the latch 30 with his ergot 34.
- the element 30 is slipped to come into stop on the first sector 5. This corresponds to the element 30 at a position relative to the part of housing 11 such that the pin 34 is in vis-à-vis a notch 15 machined in the part of 11. Then just exercise on the lock 30 a push up (for the representation of Figures 5 and 6) for the pin 34 to enter the notch 15, the latch 30 being then in raised position.
- the second sector 5 can then be pushed to lock 30.
- This second sector 5 present, at the end in contact with the latch 30, a clearance 23 such as a portion of the outer segment 6 goes under lock 30.
- Anti-rotation bolt 40 of joint plane shown in Figure 4 is mounted in the same way than the lock in Figure 3. It is formed of an element 25 between the two sides of the casing. Element 41 is extended by an outer edge 42 and an inner edge 43. The outer edge 42 has a lug 44 projecting from the plane of element 41. The same applies to the lug 45 of the edge interior 43.
