Optimum Calculation of Partial Transmission Ratios of Mechanical Driven Systems Using a V-Belt and a Three-Step Bevel Helical Gearbox

This paper introduces a study on the optimum determination of partial transmission ratios of a mechanical drive system using a V-belt and a three-step bevel helical gearbox for getting the minimum height of the system. In the study, the height of the system was chosen as the objective function. Also, in the optimization problem, the design equation for pitting resistance of a gear set was investigated. Besides, equations on moment equilibrium condition of a mechanic system including a V-belt and a three-step bevel helical gear-box and their regular resistance condition were analyzed. From the results of the study, effective models for calculation of the partial ratios of the V-belt and a three-step bevel helical gearbox were reported. As the models are explicit, the partial ratios can be calculated accurately and simply.
