1. A device for distributing oil in an aircraft turbine engine, comprising:
a rolling bearing comprising an internal ring and an external ring,
an oil distribution ring configured to be mounted on a turbine engine shaft, said oil distribution ring comprising:
i) an external cylindrical surface for mounting the internal ring of the rolling bearing,
ii) an annular shoulder for supporting a first axial end of the internal ring, and
iii) an oil recovery scoop feeding a lubrication circuit of said rolling bearing,
an annular track of a dynamic joint,
wherein the device further comprises a nut screwed onto a thread of the oil distribution ring and being supported axially on a second axial end of the internal ring in order to tighten the internal ring axially against said annular shoulder, and in that said annular track is configured so as to be in axial support on said oil distribution ring and comprises rotation-locking elements cooperating with complementary elements of the nut.
