Rolling bearing for a turbocharger

摘要

A rolling bearing (6), in particular for a turbocharger, having an outer ring (10), an inner ring (11) which is rotatable relative to the outer ring (10) about an axis of rotation (14), and having a number of rolling bodies (19) which are guided in a cage (24) between the outer ring (10) and the inner ring (11). Here, the cage (24) has, on its inner circumference, a guide surface (25) which is guided on a guide track (26) on the outer circumference of the inner ring (11). A groove (32) with a free region (34) extends on the outer circumference of the inner ring (11). The groove (32) includes a groove base (33) which rises in a radial direction toward the guide surface (25). Oil is applied to the free region (34) of the groove (32) via a spray oil hole (22) in the outer ring (10).
