Abstract
A turbocharger assembly can include a shaft having a rotational axis where the shaft includes a turbine wheel that includes a hub portion; a bearing that includes an outer race, an inner race operatively coupled to the shaft, and rolling elements disposed between the inner race and the outer race where an inner radius of the outer race and an outer radius of the inner race define a radial gap; and a lubricant slinger disposed axially between the inner race and the hub portion of the turbine wheel where the lubricant slinger includes a surface that faces and slopes away from the radial gap.

A turbocharger assembly comprising:
- a center housing that comprises a through bore;
- a shaft having a rotational axis wherein the shaft comprises a turbine wheel that comprises a hub portion;
- a bearing that comprises an outer race, an inner race operatively coupled to the shaft, and rolling elements disposed between the inner race and the outer race wherein an inner radius of the outer race and an outer radius of the inner race define a radial gap and wherein a radial clearance for a lubricant film exists between a surface of the through bore and an outer surface of the outer race;
- and
- a lubricant slinger disposed axially between the inner race and the hub portion of the turbine wheel wherein the lubricant slinger comprises a surface that faces and slopes away from the radial gap, wherein the lubricant slinger comprises a maximum radius that is less than a radius of the surface of the through bore and wherein the lubricant slinger comprises an annular groove that comprises a minimum radius that is greater than the inner radius of the outer race.
