In this study, the mesh stiffness characteristics of helical gears are evaluated by applying the finite element method. The bending and shear deflections on the contact line are obtained by the finite element method, and the contact deflections are obtained using the equation of Weber and Banaschek. Finally, using the influence method, contact ratio and load sharing ratio, the mesh stiffness characteristics of helical gears are evaluated. The results obtained could be summarized as follows: 1) By increasing the facewidth and helix angle of helical gears, a more constant mesh stiffness and transmission errors are obtained. 2) m_p+m_f〈2.0 The characteristics of this class helical gear pair are similar to that of spur gear. 3) m_p+ 1.0m_f≥2.0 This class helical gear pair gives a good performance as expected from helical gears.
