The bearing is of a type particularly suitable for three-phase generators for motor-vehicles. A bearing plate (11) includes a bearing housing (12) having a base (13). A ball bearing, comprising an outer race (14), balls (15) and an inner race (16), is fitted in the bearing housing (12). The outer race (14) is displaceable in the bearing housing (12). The inner race (16) is rigidly mounted on the end of a machine shaft (17). A resilient ring (18) is interposed between the base (13) of the bearing housing and the outer race (14) one side of which ring abuts against the base (13) and its other side presses against the outer race (14). The external diameter of the ring (18) is somewhat smaller than the internal diameter of the bearing housing (12). The ring (18) has preferably a V-shaped cross section, the opening of the V being directed radially outwardly. The space between the journal of the shaft (17) the base (13) of the bearing housing (12) and the resilient ring is filled with lubricating grease. |
