Method for introducing a balancing mark in the compressor wheel of an exhaust gas turbocharger and exhaust gas turbocharger with a compressor wheel having a balancing mark

摘要

The invention relates to a method for introducing a balancing mark in the compressor wheel of an exhaust gas turbocharger. In this method, first a movement of a milling tool in a first direction for introducing a recess in the compressor wheel and then a leakage of the milling tool located in the recess in a second direction to convert the recess into a pear segment-shaped balancing mark. Furthermore, the invention relates to an exhaust gas turbocharger, which includes a compressor wheel having one or more pear segment-shaped balancing marks.
