ABSTRACT:
To provide for effective lubrication of a vehicular-type alternator, the bearings (2, 4) positioned at the respective end plates (1, 5) are pressure-lubricated. An oil pressure supply duct (21) is directed towards the rear bearing (4) which is positioned within a chamber (23), the chamber communicating with the central longitudinal bore (24) extending through the shaft towards the drive bearing (2). The drive bearing is positioned within a second chamber (26, 29) and radial bores (25) extend from the central bore (24) in the shaft into the drive side chamber, the drive side chamber being connected to a drain duct 30. To provide communication between the end faces of the bearings, a sickle-shaped recess extends partially circumferentially around the outer race of the respective bearing in the zone of termination of the ducts (21, 30), and having an axial length longer than the respective outer race (34) of the bearing.
