Multi-plane lubricated bearing assembly.

摘要

A bearing assembly (10) includes a split inner race (18) having a first (26) and second inner (28) race halves joined together at a split line. A plurality of center feed passages (36) are provided at the split line, and at least one radial pilot passage (38) is provided in one of the inner race halves and axially spaced from the center feed passages. A bifurcated distribution manifold (40) is disposed at the split line and includes a center distribution manifold (40a) disposed in flow communication with the center feed passages, and a pilot distribution manifold (40a,40b) disposed in flow communication with solely the pilot passage. The bifurcated distribution manifold (40) ensures the independent channeling of lubricating oil to both the center feed passages (36) and the pilot passage under centrifugal force upon rotation of the inner race (18).
