Large waviness in transmission error curves mainly comes from gear radial eccentricity. On the other hand, axial eccentricity, whose parameter value is a half of axial runout, is also regarded as one of the other factors causing waviness components in transmission error. In this paper, transmission error with extremely large amount of axial eccentricity was measured and the influence of axial eccentricity was investigated. From geometrical consideration, it is expected that transmission error with axial eccentricity has two periodic waviness components in one rotation. Measured result showed that transmission error has only one periodic waviness component in one rotation at first sight. However, after applying best-fit identification of radial eccentricity and elimination of pure radial eccentricity components from measured transmission error, two periodic waviness components appeared dramatically. As expected, axial eccentricity doesn't have so great influence on transmission error waviness. Radial eccentricity dominates the waviness components in usual eccentric misalignment.
