Abstract:
1. An assembly for a turbocharger, the assembly comprising: a housing comprising a substantially cylindrical bore having a longitudinal axis, a first bore end, a second bore end, and a housing opening between the two ends, wherein at least a part of the housing opening comprises a taper; a bearing cartridge comprising an outer race, an inner race, and a cartridge opening defined by a cartridge surface, wherein the bearing cartridge is positioned within said housing substantially centered on the longitudinal axis between the first bore end and the second bore end such that the cartridge opening is substantially aligned with the housing opening; and an elongate pin having a taper body portion and a first protruding feature, wherein the first protruding feature comprises a substantially spheroid shape; wherein the elongate pin is positioned within the housing opening and the first protruding feature of the elongate pin is at least partially disposed within the cartridge opening; such that, the taper of the body portion of the pin mates with the taper of the housing opening to maintain the pin in substantially the same position relative to the housing and the first protruding feature of the pin mates with the cartridge surface such that the first protruding feature substantially restricts the bearing cartridge from surging and rolling but substantially permits heaving, swaying, pitching, and yawing of the bearing cartridge.
