Abstract:Closure technique for measuring gear pitch deviation was proposed by PTB and NMIJ, which can eliminate systematic error in pitch measurement. In closure technique method, the gear's position was changed repeatedly, and pitch deviations were also measured. Through processing measurement data, the systematic errors in pitch measurement can be eliminated. Two-step method for measuring pitch deviation was introduced in the paper, in which position of the gear was changed only two times, and the systematic error can be also eliminated. A gear's single pitch deviation was measured when closure technique and two-step method were used respectively, and difference of two measurement results was 0.15 mu m.
