A study on optimal calculation of partial transmission ratios of four-step helical gearboxes with second and fourth step double gear-sets

摘要

In this paper, a new study on the applications of optimization and regression analysis techniques for optimal calculation of partial ratios of four-step helical gearboxes with second and fourth step double gear-sets for getting minimal cross section dimension of the gearboxes is presented. In the study, from the moment equilibrium condition of a mechanic system including gear units and their regular resistance condition, an optimization program for determining the partial ratios of the gearboxes are carried out. In addition, regression analysis was carried out based on the optimization program results and explicit models for prediction of the partial ratios are proposed. Using these models, the determination of the partial ratios is accurate and effortless.
