Abstract: A turbocharger includes a turbine housing defining a turbine housing interior, a turbine wheel disposed within the turbine housing interior, a shaft coupled to and rotatable by the turbine wheel, a compressor housing defining a compressor housing interior and a flow path, and a compressor wheel disposed within the compressor housing interior and coupled to the shaft. The compressor wheel has a hub coupled to the shaft, and a plurality of impeller blades extending radially from the hub. The plurality of impeller blades define an inducer end having an inducer diameter, and an exducer end having an exducer diameter greater than the inducer diameter. The inducer diameter and the exducer diameter establish a compressor trim. The compressor wheel also has a compressor wheel shroud disposed about the plurality of impeller blades. The compressor wheel shroud encloses the plurality of impeller blades to define a shroud interior.

Abstract: A centrifugal compressor wheel assembly that can be employed in devices such as turbochargers or as a component for mechanisms requiring a compressor wheel assembly that includes a tubular insert with a compressor wheel member connected thereto which engages a shaft and a turbocharger including the compressor wheel assembly. The tubular insert has a wall member defining a shaft bore that extends from an inlet end to an opposed outlet end. The wall member has an outer circumferential surface and an opposed inner circumferential surface. At least one engagement member may be defined on the inner circumferential surface. An engagement member may be defined on the outer circumferential surface. The tubular insert can be composed of a suitable metal.

Abstract: In one aspect of the present disclosure, a compressor wheel is disclosed that includes a body, a plurality of blades, and one or more supports. The supports add strength to the compressor wheel and may be configured as ribs, for example. The body has a first face (e.g., an outer or front face), which may include the blades, and a second face (e.g. an inner or rear face), which may include the supports. The supports may include an arcuate configuration curving forward in a direction of rotation of the compressor wheel.

Abstract: A number of variations may include a product comprising a bearing housing comprising a body having an internal cavity defined by an inner surface of the body, wherein a first end of the body includes an end face and a second end of the body opposite of the end face is open, wherein the end face further comprises a through hole defined by an inner surface of the end face; and an end plate constructed and arranged to attach to the second end of the body of the bearing housing, wherein the end plate further comprise a first face and a second face, and an opening defined by an inner surface of the end plate.

Abstract: A turbocharger (1) includes compressor and turbine wheels (4, 5) and a shaft (6) that connects the compressor wheel (5) to the turbine wheel (4). The shaft (6) is supported by a thrust bearing assembly (20) that includes a pair of thrust washers (42a, 42b) mounted on the shaft (6), a hollow, cylindrical spacer (80) disposed on the shaft (6) between and abutting first faces (44) of the thrust washers (42a, 42b), and a thrust bearing (100) supported on the spacer (80) between the thrust washers (42a, 42b). One of the thrust bearing (100) or the first and second thrust washers (42a, 42b) includes a copper-alloy lining (60) where the lining (60) is provided in a first region (58a) and in a second region (58b), and the remainder of the thrust bearing (100) or the first and second thrust washers (42a, 42b) is lining free.
