Single-row ball bearing with integrated squeeze-film damper

摘要

In accordance with one aspect of the present disclosure, a rolling element bearing assembly is disclosed. The rolling element bearing assembly may be used in an electrically-assisted turbocharger. The bearing assembly includes an inner race having an outer diameter defining an inner raceway, an outer race having an outer diameter and an inner diameter, the outer-race inner diameter defining an outer raceway, a single row of rolling elements between the inner raceway and the outer raceway, and a squeeze-film damper integrated with the outer race to form a single component. The squeeze-film damper provides for a squeeze-film damper surface between the outer-race outer diameter and a housing.
