Patent number: 9850820Abstract: A power transmission system for a turbine engine is provided. The power transmission system includes a transmission shaft that is connected to a drive shaft by bevel gears, and that drives equipment or accessories. The transmission shaft is designed to operate under supercritical conditions and includes a damper system for damping vibration at its resonant speed.Type: GrantFiled: October 3, 2014Date of Patent: December 26, 2017Assignees: SNECMA, HISPANO SUIZAInventors: Serge Dominique Pettinotti, Vincent Abousleiman, Sebastien Bourget, Mickael Moreiras, Diane Gueudry, Bernard Cartier, Florian Poinsot-Berthelot

Patent number: 9638107Abstract: A gas turbine AGB has a front lateral face, a rear lateral face opposite from the front lateral face, and a peripheral rim closing the box. At least one gear train is mounted in the AGB and is made up of a plurality of gearwheels meshing together, and designed to be coupled to a drive shaft for driving an accessory. The AGB further comprises, mounted between a central shaft carrying each gearwheel and the drive shaft, a decoupling unit for decoupling the accessory and constituted by a dog clutch having axial teeth co-operating with complementary teeth of the central shaft. The dog clutch includes internal fluting engaged with the corresponding external fluting of the drive shaft. The decoupling unit is controlled by an electric actuator acting on the movement of a plunger pin having one end co-operating with an outer helical groove in the dog clutch.Type: GrantFiled: July 2, 2012Date of Patent: May 2, 2017Assignee: HISPANO SUIZAInventors: Vincent Abousleiman, Romaric Fritz

Patent number: 8887889Abstract: 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.Type: GrantFiled: November 15, 2010Date of Patent: November 18, 2014Assignee: Hispano SuizaInventors: Vincent Abousleiman, Sylvain Canard, Andre Raymond Christian Deperrois, Romaric Fritz
