Abstract

This work deals with the determination of optimal gear ratios of three-step bevel helical reducers. To find the optimal ratios, an optimization problem was created and solved. In this problem, the minimal reducer cross section was selected for the target. Also, seven main design parameters counting the total ratio, the allowable contact stresses and the face width coefficients of all steps and the output torque were chosen for the examination of the effects of them to the optimal gear ratios. In addition, to estimate the weight of these parameters on the optimum ratios, a simulation experiment was carried out by programming. From the experimental results, the influence of the design factors on the optimal gear ratios was found, and an equation to find the optimal gear ratios was presented.
