For the purpose of clarifying the influence of tooth errors on the vibration behavior of power transmission helical gear pair with comparatively narrow face width, the nondimensional equation of the rotational motion has been numerically solved taking several kinds of errors into account. And the performance diagrams on vibration have been introduced, in which the acceleration level is shown by contour lines on the contact ratio plane which is formed by the transverse contact ratio (abscissa) and the overlap ratio (ordinate) . It has been made clear that the influence of the errors on the vibration depends upon the kind of error as well as the contact ratio and the rotational speed.
