誤差を考慮したはすば歯車の軽負荷における回転方向振動解析 : 第3報, 歯すじ方向誤差と振動性能曲線

For the purpose of a detailed description of rotational vibratory response of a helical gear pair having tooth surface deviation during light load transmission, we have already developed the numerical calculation method for gear vibration which can take any type of deviation into account. In this paper, we show the 'Performance diagram', in which the acceleration level is shown by contour lines on the contact ratio plane formed by the transverse contact ratio (abscissa) and the overlap ratio (ordinate). With these diagrams, the vibration characteristics of each type of tooth surface deviation become clear. The optimal and worst gear parameters are discussed.
