1. A lubrication device for a turbomachine reduction gear having a main axis,
the device comprising an annular lubricating oil collecting cup delimited by a first wall and a second wall,
said cup being divided by internal walls extending between the first wall and the second wall so as to define a plurality of angular sectors forming oil collecting basins, the basins being circumferentially adjacent around the axis and comprising lubricating oil outlets intended for the lubrication of the reduction gear,
wherein one or more of said internal walls have openings allowing oil to pass between the circumferentially adjacent basins
wherein said openings are formed in one or more of said internal walls so as to define one or more rows of openings in said one or more internal walls.
