BALANCING METHOD FOR A TURBOCHARGER

A method of balancing turbocharger rotating assembly (50) includes installing a shaft-and-turbine wheel sub-assembly (40) into a ball bearing cartridge (20) within a bearing housing (8) of a turbocharger (1), connecting a compressor wheel (5) to the shaft (6), and testing the balance of the turbocha...

Zusammenfassung:	A method of balancing turbocharger rotating assembly (50) includes installing a shaft-and-turbine wheel sub-assembly (40) into a ball bearing cartridge (20) within a bearing housing (8) of a turbocharger (1), connecting a compressor wheel (5) to the shaft (6), and testing the balance of the turbocharger rotating assembly (50) while the turbocharger rotating assembly (50) is installed within the bearing housing (8) of the turbocharger (1). Based on the results of the balance testing, material is removed from the turbine wheel (4) while the shaft-and-turbine wheel sub-assembly (40) is installed within the bearing housing (8) of the turbocharger (1). The step of removing the material from the turbine wheel (4) comprises removing material from a peripheral edge (35) of a backwall (34) of the turbine wheel (4).
