Abstract
A lubrication system is provided for use with a bearing including an outer race, an inner race, and bearing elements disposed therebetween. Rotation of the bearing and a shaft journaled thereby induces air movement having a first air velocity and a path adjacent the bearing. The lubrication system includes a structure providing a passageway through which a lubricant entrained in gas is delivered at a second velocity to the bearing. The lubrication system further includes a flow modifier disposed relative to the bearing and the structure to modify the first air velocity to promote movement of the lubricant into the bearing.
