Patent ID: 10451114

Abstract:
An inner ring for a bearing comprises a ring body including outer and inner surfaces each extending in a circumferential direction about a longitudinal axis. The outer surface is disposed radially outside the inner surface and includes (a) a raceway for supporting circumferentially arranged rolling elements, (b) a forward separator land, and (c) an aft separator land, where the raceway is axially situated between the forward and aft separator lands. The inner surface includes an annular groove for containing a lubricant under centrifugal forces. Flow passages for distributing the lubricant extend through the ring body from the inner surface to the outer surface, including a set of first flow passages extending from the annular groove to the raceway, a set of second flow passages extending from the annular groove to the forward separator land, and a set of third flow passages extending from the annular groove to the aft separator land.
