Abstract

L'invention concerne une turbomachine (1), comportant un arbre de soufflante (4), un arbre d’une turbine (3) couplé audit arbre (4) via un réducteur (6), un circuit principal (7) et une pompe auxiliaire (70) de lubrification dudit réducteur (6) comportant un rotor (74) entrainé autour d’un axe (A) par un dispositif de prélèvement de puissance (8) sur l’un desdits arbres (3, 4), et un système de freinage (9) du rotor (74) comportant des premières dents (92) complémentaires de secondes dents (72) portées par ledit rotor (74), ledit système (9) est mobile en translation le long de l’axe (A) entre une position de couplage dans laquelle lesdites dents (92, 72) sont engagées et une position de découplage dans laquelle lesdites dents (92, 72) sont désengagées, sélectivement en fonction d’un seuil de couple transmis par le rotor au système dans chacun des deux sens de rotation (S1, S2). Figure pour l'abrégé : Figure 2The invention relates to a turbomachine (1), comprising a fan shaft (4), a turbine shaft (3) coupled to said shaft (4) via a reduction gear (6), a main circuit (7) and a pump auxiliary (70) for lubricating said reducer (6) comprising a rotor (74) driven around an axis (A) by a power tapping device (8) on one of said shafts (3, 4), and a braking system (9) of the rotor (74) comprising first teeth (92) complementary to second teeth (72) carried by the said rotor (74), the said system (9) is movable in translation along the axis (A ) between a coupling position in which said teeth (92, 72) are engaged and a decoupling position in which said teeth (92, 72) are disengaged, selectively as a function of a torque threshold transmitted by the rotor to the system in each of the two directions of rotation (S1, S2).
