摘要:
The present invention relates to a joining device (10) comprising a clevis (22) and a connecting member (28), the member (28) pierced with a through hole (30) being housed between a first and a second lug (26a, 26b) of the clevis, these lugs respectively having a first clevis hole (32a) and a second clevis hole (32b), the device further comprising a shear pin system (36) passing through each of said holes (32a, 32b, 30) and comprising a threaded end (46) collaborating with a nut system (44) bearing against the second lug.According to the invention, the shear pin system comprises a widened portion (42) passing through the first hole and forming a shoulder (50) situated between the two lugs, the member situated some distance from the first lug being pressed against the shoulder (50) on the one hand and against the second lug (26b) on the other.
摘要:
A joining device including a clevis and a connecting member is disclosed. The connecting member includes a through hole which is housed between a first and a second lug of the clevis. These lugs respectively have a first clevis hole and a second clevis hole. The device further includes a shear pin system passing through each of the holes and includes a threaded end collaborating with a nut system which abuts against the second lug. The shear pin system includes a widened portion passing through the first hole and forming a shoulder situated between the two lugs. The member is situated away from the first lug. A first side of the member is pressed against the shoulder and a second side of the member is pressed against the second lug.

The connection assembly of an arm to a sleeve is carried out substantially by parts of axes crossing the arm and the spacers between the parts of axes and the sleeve and the assembly bolts. The assembly and the disassembly are easy, even with highly reduced encumbrance, as the connection is light and devoid of high internal efforts, and a good position precision is obtained. The assembly may be applied to stators with an exterior sleeve and, an interior hub and radial link arms, which are encountered in certain turbomachines.

摘要:
The present invention relates to a two-spool gas turbine engine including an HP turbine stator ring and an exterior wall of the transition channel between the HP and LP stages, a first enclosure for controlling the stator ring, and a second enclosure for distributing air for blowing the exterior wall of the transition channel. The engine is characterized in that the two enclosures are placed in communication via an orifice controlled by a valve adapted to be open when the pressure P1 in the first enclosure is greater than the pressure P2 in the second enclosure, and closed when P1

The invention relates to an inter-turbine casing (40) for a turbofan (2), comprising an outer ring (44), an inner ring (54), and an intermediate ring (52) between the inner ring and the outer ring, the inner (54) and intermediate (52) rings having respective openings (540, 520) for the passage of cooling air. The casing is distinguished in that it comprises at least one sealing device (80), arranged between the outer ring (44) and the intermediate ring (52), with a base (82), provided with at least one orifice (90) for the passage of cooling air, and a peripheral skirt (84) which is able to be compressed and expanded elastically, the base (82) bearing against the outer ring (44) and the peripheral skirt (84) bearing against the intermediate ring (52).

摘要:
A sealing device for a nozzle of a turbomachine turbine including a turbine rotor. The turbine nozzle includes at least one inner annular platform. The turbine rotor includes a downstream spoiler disposed substantially axially. The sealing device includes at least one sealing sheet disposed, radially, between the inner face of the inner platform and the downstream spoiler of the rotor of the turbine so as to form an overlap clearance.
