The purpose of this study was to try to clarify relative relationships among deviations on each tooth of gears by using the graph theory. Our previous study proposed a method to derive correlation coefficients among the tooth helix deviations and applied it to a ground helical gear. In addition, the coefficients were used as edges, and a network image of the relative helix deviations was generated. In this paper, this method was applied to the analysis of super-finished helical gears, and the phase relationship among the helix deviations was derived. Furthermore, this paper proposed a method, which enables us to derive the magnitude of helix deviation as a norm of signal, which disappeared from the phase network. Then, the derived magnitude was added to the network as the intensity of the vertices. As a result of the application of the proposed method to an analysis of the ground and super-finished helical gears, it was found that the newly created network images were able to show the different characteristics between the gear-finishing processes.
