  • Noise damped dynamo electric machine, especially vehicular type alternator
    Patent number: 4734600
    Abstract: In an apparatus for noise reduction and damping in ventilators of electric machines, in particular vehicular alternators, it is proposed that the ventilator support on the rotor shaft be effected by axially staggering inner rubber inlays on both sides and providing adjoining outer spring pressure elements such that the ventilator region is clamped, at least in the axial direction and preferably radially as well with an additional rubber ring. As a result, the transfer of resonant vibrations of the rotor to the ventilator are reliably avoided, and the noise emissions are decisively reduced.
