Floating ring bearing structure and turbocharger employing same.

摘要

A bearing structure including a bearing housing, a thrust sleeve retained within the bearing housing, a pair of bearing sleeves received within the bearing housing on opposite sides of the thrust sleeve, and a shaft received within the thrust sleeve and bearing sleeves. The thrust sleeve is retained in a manner to permit movement of the thrust bearing relative the bearing housing to correspond with movement of the bearing sleeves to maintain parallelism between the associated end bearing surfaces on the thrust sleeve and bearing sleeves. A bearing structure for receiving radial and axial thrust loads and a turbocharger employing the described bearing structures are also disclosed.
