Aimed at some questions of the rotated gear in the conventional steam turbine center, such as the uneven force and local stress concentration along the radial direction of the gear, based on governing equations and Stodola’s mathematical model, this study made use of the idea of partial differential equations to make axisymmetric and uniform thickness gear modeling under constraint conditions of specified gear mass and moment of inertia and optimization algorithm is used to obtain the thickness profile that results in a radial stress distribution that is as even as possible. The maximum radial stress via the optimization design of the gear decreases by about 25% in contrast with the maximum radial stress of the gear with the even thickness profile.
