This paper introduces an optimization study to design the smallest mass gearbox. To carry out this study, a simulation experiment with 10 main design parameters was designed and conducted. From the results of this experiment, the influence of the main design parameters on the optimum gear ratios of the gearbox was investigated. In addition, regression formulas to determine the optimum gear ratios aiming at the minimum gearbox mass have been proposed. The formulas found are in the form of explicit functions, so they are very convenient for practical application.
