Abstract
A turbocharger rotor has a turbine wheel and shaft, a compressor wheel and adapter and a separate thrust runner clamped together by a fastener rod. The adapter is piloted on the shaft and the thrust runner is piloted on the adapter, which has annular ends engaging the shaft and adapter for torque transmission between the turbine and compressor wheels. An anti-rotation coupling relates the phase angles of the shaft with the adapter and the thrust runner during assembly. Opposed radial thrust faces on the thrust runner and adapter are disposed at opposite ends of a compressor bearing journal on the adapter to allow placement of mating bearings on a single element of a turbocharger housing. Advantages include simplification of manufacture and assembly of the rotor in a turbocharger housing.
