PROBLEM TO BE SOLVED: To provide a drive (6) for a helicopter. SOLUTION: The drive (6) comprises at least one rotary member (10, 11); a casing housing the rotary member (10, 11) and defining a compartment (9) containing a lubricating fluid and air; and a separating means (23) for separating the lubricating fluid from the air and retaining the lubricating fluid inside the casing (8) in the presence of airflow outward of the casing (8) and produced by pressure gradients between the compartment (9) and the outside. The separating means (23) are angularly integral with the rotary members (10, 11) to centrifugally separate the lubricating fluid from the air radially with respect to the axis (A).
