Abstract

A rotating shaft device, comprising a fixed carter (21) and driving means integral to at least one of one or more rotating shafts (8) of the rotating shaft device, each driving means having its own integrated control and power supply unit (11, 25), allows the transmission of signals, even with low intensity, to this unit and to this regard it comprises: one or more annular antennas (24), connected to said respective control and power supply unit (11, 25) and arranged so as to at least partially surround one or more of said rotating shafts (8), and integral to the rotating shaft (8) of the respective control and power supply unit (11, 25), so that said rotating shafts (8) act as wave guide for the signals received from said one or more annular antennas (24) and intended to be received by the respective control and power supply unit (11, 25) to drive said driving means associated thereto; and radio transmission means (26), integral with the carter (21) and associated to one or more of said rotating shafts (8) to send signals therethrough to said one or more annular antennas (24).
