A Study on Optimization of Helical Worm Gearboxes Based on Volume Function

This paper aims to determine the optimal gear ratios of a helical worm gearbox in order to achieve the smallest gearbox volume. To solve this problem, a simulation experiment is designed and carried out. In the experiment, four main input factors including the total gearbox ratio, the coefficient of wheel face of stage 2, the allowable contact stress of stage 2, and the output torque were investigated. The effect of input factors on optimal gear ratios was evaluated. A regression formula for determining the optimal gear ratio has also been proposed.
