摘要：

This paper presents a study on the optimal determination of gear ratios of worm-helical gearboxes. In this study, the acreage of the cross section of the gearbox was chosen as the objective function of the optimization problem. Furthermore, the design equations for pitting resistance of the worm and the gear set were considered. In addition, equations on moment equilibrium condition of a mechanic system including two-gear unit of the gearbox and their regular resistance condition were analysed. From the results of the optimization problem, equations for determining the optimum partial ratios of the two stages of the gearbox were proposed. Based on these models, the partial ratios are calculated accurately and simply.
