Abstract: The gears are caused wear and tear because of relative sliding tooth surface contact in the transmission process. Due to the factors of uneven teeth direction interface and axis flexure deformation, such as the abrasion quantity of gear is different on direction of the tooth profile. The common normal micrometer or roll bar dimension are mainly for dividing circle between tooth thickness measurement so it cannot get feedback from other abrasion of cross section profile. Based on the situation above, the measurement methods were studied in this paper. More than one section are measured by the proofing paste method, and then reckon chordal tooth thickness of the each section, it is concluded that the cross section of the wear volume can accurately reflect the gear working state.
