Abstract
A planetary reduction gear () for an aircraft turbine engine, said reduction gear comprising a rotatable sun gear, a rotatable ring gear () and satellite gears meshed with the sun gear and the ring gear and carried by a planet carrier intended to be fixed to a stator, the reduction gear further comprising an annular trough for recovering and channelling lubrication oil that is mounted around the ring gear, characterised in that the reduction gear further comprises an annular deflector () fixed to the ring gear and configured to route the oil exiting radially towards the outside of the ring gear up to the trough by virtue of centrifugal forces, the trough comprising an annular chamber () which is axially remote relative to a median plane (P) substantially passing through the centre of the ring gear, and an annular duct () located on a side of said chamber and emerging in said chamber.
