| Abstract: | By the theoretical way, the parameters of the tangent circular fillet and the circular fillet with undercut are deduced, and the method of practical application is proposed. By simulating the machining of involute gears, 3 D models of the gear with and without circular fillet are separately created. With finite element method, their bending stresses are analyzed and the results show that the bending stress of pinion reduces 33%. The analysis shows that it can increase gear bending strength to use circular fillet. |
