Load sharing ratio of crossed helical gear was calculated by the based on stiffness at the point of contact between tooth surfaces. The stiffness was calculated by the displacement, which was analyzed by using a three dimensional finite element method (FEM) and theoretical elastic displacement. The theoretical analysis of displacement of contact was small. The FEM analysis showed that the bending stiffness reduce near the both sides of tooth. This reduction of bending, stiffness causes the load sharing ratio to change.
