In the article, key problems of on-line tooth profile measurement of large gear are analyzed. And the measuring method, in which a rack-edge probe engages with the tooth profile to be measured in the across-section, is presented. Thus profile errors can be measured and the instrument size are reduced. It is shown that the accurate measurement can be carried out even if the instrument precision is not too high.
