Abstract (en)
[origin: EP2581553A1] The method involves arranging a turbine housing (1) and a compressor housing (2) at a distance from each other at a machine bed (3). The turbine housing is connected with compressed air sources, and a rotor (6) is accelerated by driving a turbine wheel (7) with pressurized air at normal operating speed. Oscillations induced by imbalance, at a unit housing (5) are measured during rotation of the rotor with the normal speed. Phase position of the oscillations is determined. The measured oscillations and the phase position are utilized to determine imbalance of the rotor to be adjusted. An independent claim is also included for a device for dynamic measurement of imbalance of a rotor of a turbo supercharger core assembly.
