Abstract：

For the problems of excessive force acting on the concave cavity and insufficient filling of tooth height during the forming of the double cone roller rolling for spiral bevel gear, the rolling process of double cone roller for the driven spiral bevel gear was simulated by finite element software DEFORM3D firstly, and the influences of friction coefficient, rolling temperature, feeding velocity of concave cavity on the equivalent stress of concave cavity and the forming tooth height along Zdirection were studied. Secondly, the optimum process parameters were obtained and verified numerically by the orthogonal test design method with the optimized indexes of the equivalent stress of concave cavity and the forming tooth height along Zdirection. Finally, the feasibility of double cone roller rolling process for driven spiral bevel gear was proved by numerical analysis and compared with the results in the literature. The results show that when the friction coefficient is 0.2, the rolling temperature is 900 ℃, and the feeding velocity of concave cavity is 2 mm·s-1, the force of concave cavity is the smallest, and the filling of tooth shape is full with the highest tooth height.
