Definitions

  • the invention relates to an X-ray diagnostic generator with a rotating anode X-ray tube and a feed circuit for the rotating anode motor.
  • the anode speed is determined individually, it is possible that it takes on values at which resonance vibrations occur in the bearings. This can damage the bearings.
  • the invention has for its object to provide an X-ray diagnostic generator of the type mentioned in such a way that the occurrence of resonance vibrations in the anode bearing is prevented when the anode speed is individually determined.
  • a vibration detector is present which slightly changes a set speed value if resonances occur in the motor mounting.
  • the vibration detector detects the occurrence of resonance vibrations and immediately gives this information to the drive unit for the rotating anode motor. This now corrects the drive frequency minimally up or down so that the resonance vibrations disappear again.
  • a rotating anode X-ray tube 1 is shown with a rotating anode motor 2, which is supplied with anode and heating voltage by a supply circuit 3.
  • the rotating anode motor 2 is supplied by a supply circuit 4 with a suitable supply voltage, which is determined in such a way that the optimum motor speed and thus anode speed result for the respective recording parameters.
  • the feed circuits 3, 4 each contain a mains rectifier and a downstream inverter.
  • the rotary anode motor 2 is assigned a vibration detector 5, which detects the occurrence of resonance vibrations in the anode bearing and causes a processor 6 that in this case the feed frequency and thus the anode speed is changed slightly up or down, so that the resonance vibrations disappear and so that no bearing damage occurs.
  • the processor 6 receives at its input 7 a signal which corresponds to the target value for the anode speed determined by a recording data computer. This setpoint is changed slightly in the sense described above when resonance vibrations occur.
