Abstract:
A circumferential lubricant scoop for providing lubricant to a bearing assembly. The scoop is disposed circumferentially about and rotates with a rotor shaft. The scoop comprises a plurality of lubricant capturing vanes shaped to capture and retain lubricant in a cavity behind a lower lip of the vane. This cavity is in fluid communication with channels leading to fluid pathways of an inner race of the bearing assembly. Fluid is moved through the channels and fluid pathways due to the rotational force imparted by the rotating rotor shaft.
