Title: Variable preload shaft bearing for turbocharger

Abstract

This patent describes a bearing structure of a turbocharger for an internal combustion engine, comprising; a stationary bearing housing having at least one fluid passage for conveying a lubricating oil; first and second rolling bearings disposed in the bearing housing for supporting a rotating shaft; a first collar member interposed between the housing and the first bearing and a second collar member interposed between the housing and the second bearing. The first and second bearings are supported by the bearing housing through the first and second collar members, and preloading means disposed-between the first and second collar members. The preloading means form an oil chamber receiving the lubricating oil supplied through the fluid passage of the housing, and pushes each of the first and second collar members with a force whose magnitude is variable in dependence on an oil pressure.
