Abstract
A rotating machine mounted on a rotating shaft has a rotor turned by the ating shaft and a stator mounted for free rotation with respect to said shaft. The stator comprises a fly-wheel, ballasted at a point of its periphery and equipped with movable masses to compensate for imbalance in the case of accidental joining in rotation of the rotor and the stator. The disclosure shows an alternator mounted in the forward nose of an aircraft reactor, to supply power to devices located in the rotating parts.
Claims10
A rotating machine of the type comprising a rotor fixed to a drive shaft for rotation with respect to a stator, characterized by the fact that the stator is carried on a free end of the drive shaft of the rotor, said stator being mounted for free rotation with respect to said shaft and supporting first means and second means, the first means opposing in normal operation a resistant couple on the rotor, and the second means suppressing automatically perturbations caused by said first means on the drive shaft in the event of the accidental rotation of the stator with the rotor.
