摘要

An emergency lubricating device is disclosed for a reduction unit, particularly for the main gearbox of a rotary-wing aircraft, including a branch duct (10), coming from the normal lubricating circuit (3) of a rotary-wing aircraft gearbox (1), which feeds oil to at least one emergency reservoir placed at the upper part of the gearbox. The reservoir delivers the oil continuously through calibrated emergency supply ducts to the critical elements of the reduction unit (8, 9).
