The problem of minimum mass design of a single-stage helical gear unit represents a real interest, since the most commonly encountered mechanical power transmission require low weight. This paper presents an optimal design mass minimization problem of a single-stage helical gear unit, complete with the sizing of shafts, gearing and housing using genetic algorithms (GAs). It can be observed that...
