The invention relates to an accessory gearbox capable of driving the accessory devices of a gas turbine engine, such as an aircraft engine. Said accessory gearbox includes a housing and a plurality of gear wheels having axes that are parallel to one another inside the housing. The housing includes a means for attaching the accessory devices to the wall of the housing and driving them, via the gear wheels, through openings in the wall of the housing. The gear wheels are supported in the housing by rolling-element bearings. Each rolling element includes a first ring that is stationary relative to the housing, and a movable ring, secured to the gear wheel, wherein at least one (110) of said gear wheels is supported by a single rolling element (120). |
