Abstract: In view of characteristics of large gears, the general principle of a rack-head on-machine measuring large gear profile errors is stated. In the existence of error factors, the engaging process of the measuring rack and measured involute profile is analyzed by means of error-variation relation. And the precision design theory of the on-machine measuring instrument with which large gear profile errors are measured.

Key words: Engagement characteristics, Error-variation, Large gear, On-machine measurement, Profile error, Rack-head
