OSTI ID:5819141
This patent describes a method for spin-testing a turbocharger rotor. The rotor includes a shaft portion which is fixed to an assembly of component parts which include a thrust bearing, a spacer, at least one of a sleeve portion and compressor rotor portion, and a lock nut. The improvement comprises: preparing an integral composite member consisting of at least two of the component parts; dynamically balancing the turbocharger rotor, without the shaft portion fixed to the assembly; placing the turbocharger rotor and the integral composite member in a testing device, such that the shaft portion and the assembly are fixed to each other by the lock nut, and are rotatable as a unit; and rotating the turbocharger rotor and the assembly in the testing device, to effect the spin-testing.
