    摘要: A bearing system having variably grooved radial and thrust bearing with reduced groove angle near bearing entry is described. In an embodiment, the bearing system includes a housing. The bearing system also includes a shaft centrally located in the housing. The bearing system additionally includes a rotor portion that is adapted to be rotated about the shaft and contained within the housing. The bearing further includes a variably angled groove disposed on an internal surface of the bearing system. The variably angled groove reduces ingestion of air in the bearing system during operation of the bearing system.
