Protective bearing and cover assembly, for an internally ventilated rotating electrical machine, has centrally an axially orientated axis and comprises on the one hand at least one electronic component carried by the bearing and protected by the cover having at least one radial opening for the passage of air, at least one axial opening for the entry of air, a generally axially orientated skirt and a generally transversely orientated base part, in which is located the axial air inlet opening, which is offset axially in relation to the radial opening for the passage of air, and on the other at least one shaft for the cooling of the generally axially orientated electronic component; the radial opening for the passage of air constitutes the outlet of the cooling shaft whereas the skirt constitutes one of the internal and upper walls of the cooling shaft. The rotating electrical machine consists of an alternator or a starter-alternator or an alterno-starter comprising such an assembly. |
