Abstract:
A hearing arrangement which has a double-row rolling-body bearing, in particular an angular ball bearing for a turbocharger. The rolling-body bearing has at least one outer ring and at least one inner ring between which an intermediate space for two rows of rolling bodies is formed. For reliable and disruption-free lubrication, the rolling-body bearing has a central feed opening formed on the outer ring, and at least one outlet opening, lying opposite the central feed opening, on the inner ring for a lubricant. In the vicinity of each of the rows of rolling bodies, at least one feed opening is provided on the inner ring for feeding the lubricant to the rolling bodies so that the lubricant is injected via the inner ring, and the centrifugal force during the operation of the bearing is utilized.
