This paper describes a measuring method for the eccentricity and some lower-order transmission errors of the gear during rotation. Amplitude and phase of the eccentricity are estimated by the harmonic analysis on the transmission error between two pinion gears meshing together the object gear. This method measures not only the gear eccentricity generated during the manufacturing process but also deflections of the gear shaft and its bearings during operation. Transmission error of the meshing three gear system was measured by two encoders and a counter connecting to PC. The amplitude and the phase of the gear eccentricity were estimated by FFT independently of the systematic errors and misalignments of the pinion gears and the encoders. After adjusting the center of the object gear, the eccentricity decreased considerably from 262 μm to 12 μm.
