1. A turbine-engine arrangement for an aeronautical turbine engine comprising a body rotating about an axis and carrying blades, the turbine-engine arrangement comprising: equipment to be lubricated, and a circuit for lubricating the equipment comprising a pump, and a drive transmission connecting the rotating body of the turbine engine to the pump,
wherein the transmission comprises a first rotating shaft connected to the pump, two pinions with rotation axes parallel to the first shaft, and connected to the first shaft by two free-wheels with identical directions of sliding rotation, and a toothed wheel meshing with each of the pinions forming two oblique gears and driven by a second rotating shaft, connected to the rotating body by a transmission.
