Abstract

The problem of optimization of gears is difficult to solve. Indeed, the objectives are many and they require a multicriteria optimization. The compromise between the various objectives is not easy to find because the optimization criteria are often contradictory. In addition, there are a large number of design variables, and the majority of these variables takes discrete values. Worm and worm wheel drives are normally used for non-parallel, non-intersecting, right angle gear drive system where high reduction ratios are involved, though they are also employed with low to medium speed reducers in many applications. In this paper an attempt has been made to optimize worm and worm wheel design using conventional tool LINGO and heuristics as Particle Swarm Optimization (PSO) algorithms. A combined objective function which maximizes the Power, Efficiency and minimizes the overall Weight, Centre distance has been considered in this model.
