Abstract:
In accordance with one aspect of the present disclosure, a turbocharger having a rolling element bearing (REB) assembly contained within a bearing housing includes an axial damper configured to dampen and limit axial displacement of the REB assembly. The axial damper can include different embodiments, including an elastomeric axial damper, wire mesh, or oil film, for interrupting contact between the bearing assembly and a displacement limit when an axial displacement force exceeds a preload force. Further, the axial damper can include an apparatus having at least two axially compressible rings, where one of the axially compressible rings includes a displacement limit feature.
