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.
