The rotating components of an exhaust gas driven turbocharger are supported by a pair of axially separated ball bearings having an outer race and an inner race. A spacer between the bearings engages the outer race of both bearings and exerts a preload bias on the outer races of the bearings urging the outer races away from one another. Accordingly the bearings are preloaded so that centrifugal forces generated during high speed operation will not force the ball bearing away from the inner races.

Turbocharger bearing and lubrication system

Apparatus for cooling and thermally isolating turbocompressor foil bearings. The bearing journal includes a hollow shaft through which gas is positively circulated to cool the shaft. A slinger at one end of the shaft develops a centrifugal pumping action during operation of the turbocompressor by virtue of a plurality of radially directed gas passages. Pressurized gas may be introduced from the compressor into the interior of the hollow shaft and, after traversing the shaft, returned to the compressor. The invention includes arrangements for protecting the bearing against combustion products which may leak past turbine wheel seals by removing such combustion products before they can reach the bearing.

Thermal isolation system for turbochargers and like machines

A fluid bearing having a pair of members in relatively rotatable relationship with each other, and a compliant foil bearing disposed between the pair of relatively rotatable members. The compliant foil bearing has a plurality of overlapping integral compliant foil/stiffener elements with one end mounted to one of the rotatable members.

Bearing foil stiffener

A rotor assembly having wedge-shaped permanent magnets and anchors with undulating sides for attaching the rotor hub to the pole bodies.
