An exemplary bearing assembly for a turbocharger includes a center housing
with a bearing bore having a bearing bore turbine end radius and an inlet
for lubricant and a unitary bearing disposed in the bearing bore and
forming an outer lubricant film between the bearing and the bearing bore
wherein the bearing includes a central axis, an internal bore to receive
a shaft extending between a compressor end and a turbine end of the
bearing and forming an inner lubricant film between the internal bore and
the shaft, a locating mechanism between axial ends of the bearing to
prevent rotation and translation of the bearing within the bearing bore
and a turbine end protrusion wherein the protrusion comprises a radius
that exceeds the bearing bore turbine end radius to thereby deflect
lubricant from the outer lubricant film layer radially outward. Other
exemplary technologies are also disclosed.
