Abstract

See full text

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.
