Cost optimization of two-stage helical gearboxes with second stage double gear-sets

In practice, the cost of a gearbox plays very important role in trade. Therefore, reducing gearboxes is an task not only when manufacturing but also designing them. order to reduce gearbox, there are many solutions which determining optimal partial gear ratios effective measure. This because it size, mass depends greatly on ratios. work presents method for calculating function two-stage helical with second-stage double gear-sets based components that construct gearbox. The objective minimized achieve transmission Furthermore, screening experiments carried out nine input parameters have significant effects optimum ratio second stage. These total ratio, coefficient wheel face width first stage, allowable contact stress output torque, housing, gears, and shaft cost. experimental results were analysed by using Analysis Variance (ANOVA) help Minitab 19 software. demonstrate weight their interactions response was investigated. Also, regression model computing stage proposed. brings significance design process since can decrease
