Abstract
A drive pinion of an air/oil separator of an accessory gearbox of a turbomachine, the air/oil separator being configured to be supplied at the input by an air flow to de-oil and to supply at the output, on the one hand, a de-oiled air flow and, on the other hand, an oil flow by centrifugation, the pinion being configured to drive the separator rotationally along an axis of rotation, the pinion being mounted facing a passage opening of the separator, the pinion comprising at least one guiding opening traversing the web plate defining at least one guiding surface inclined with respect to the axis of rotation in such a way as to guide along the axis an air flow to de-oil into the separator or a de-oiled air flow out of the separator via the guiding opening of the pinion.
