In this article, a profile modification approach is adopted to design a spur gear set for minimization of contact stress and optimization of weight. An altering tooth sum method is used to reduce the hertzian contact stress along the path of contact. Three case studies are performed for a spur gear set with specific center distance and tooth sum of 90 (+5). A multi-objective optimization problem is formulated with contact stresses along path of contact and weight of gear set as design objectives. This nonlinear constrained optimization problem has been addressed by mean of the particle swarm optimization algorithm. Six design variables related to gear geometry and material property are used in this optimization, and all the constraints are satisfied at the optimal solution. Gear and pinion surface temperatures are below flash temperature, indicating protection against scoring wear. A higher value of AGMA scoring index is achieved in this optimum design approach. Specifically, a lighter gear with less contact stress and adequate scoring resistance is reported in this study. Promising results in terms of objective function values and computational time (cpu time) are observed. Furthermore, a CAD model is developed by means of optimized design parameters so as to check the geometric interference and practical feasibility of the design. |
