Abstract
A turbocharger rotor includes a turbine wheel, a compressor wheel, a shaft extending between the turbine and compressor wheels for rotation together about an axis, and connecting means. The connecting means include first and second joints including alignment couplings joining opposite ends of the shaft with adjoining inner ends of the compressor wheel and the turbine wheel. The couplings are configured to coaxially align and drivingly engage the shaft with the compressor and turbine wheels. A fastener rod extends through the shaft and the compressor wheel, engaging the turbine wheel to retain the rotor components together under compressive load. The rod is resiliently stretchable to limit changes in the retaining force changes in axial dimensions during operating and stationary conditions. Additional features and variations are disclosed.
