Abstract: An assembly that includes an accessory gearbox (AGB) and a tank for a liquid lubricant for a turbojet engine. The AGB includes a gear connected to parallel shafts for mechanically driving accessories. The assembly includes a housing with two compartments and a partition perpendicular to the shafts for separating the compartments, a compartment defining the accessory gearbox and a compartment defining the liquid tank. The assembly can be compact and easily manufactured.

Abstract: A device for uncoupling a drive shaft of a piece of equipment from an input shaft. The device includes a claw including first teeth and first splines to (i) move longitudinally along a first of the shafts by co-operating with second splines borne by the second of the shafts and (ii) engage or disengage the first teeth in relation to the second teeth positioned on the second shaft. The device also includes a longitudinal movement mechanism including a stationary part acting on a longitudinally mobile piece to move the claw between a coupling position and an uncoupling position. The longitudinal movement mechanism drives the claw by co-operation between a rotationally fixed piece and a piece that is linked to the claw and rotated therewith, a longitudinal clearance being maintained during operation between the piece that is rotationally fixed and the rotated piece.

Abstract: An assembly for driving accessories of a gas turbine is provided. The assembly includes: a gearbox having a front side face and a rear side face opposite the front face and having mounted therein a first gear train made up of three toothed wheels meshing with one another, and a second gear train made up of four toothed wheels meshing with one another; a power transmission shaft that is coupled in rotation with the first and second gear trains by a toothed wheel pair, and that emerges from the front side face of the gearbox; and nine distinct gas turbine accessories mounted against the side faces of the gearbox, and each including a respective drive shaft that is coupled in rotation with one of the toothed wheels of the two gear trains.

Abstract: A flexible coupling between two rotary shafts comprises a flexible metallic member rigidly connected to each of the shafts, the flexible member comprising connection zones interconnected by deformation zones which are traversed by slots perpendicular to the axis of the shafts and dividing the deformation zones into a plurality of strips which are integrally connected with each other and with the connection zones.
