Abstract: A rotary assembly comprising a transmission member and an oil distribution system enabling oil to be supplied to the transmission member in order to lubricate it. According to the invention, the oil distribution system comprises at least one oil transfer chamber provided with at least one feed orifice configured to receive oil from outside the rotary assembly; the transmission member includes at least one rotary portion provided with at least one oil reception chamber; at least one link duct provides fluid flow connection between the oil transfer chamber and the oil reception chamber; the oil distribution system is driven by said rotary portion of the transmission member to rotate together with it; and the rotary assembly is configured in such a manner as to accommodate a given amount of axial and/or radial relative movement between said rotary portion of the transmission member and the oil distribution system.
