Splitting Total Gear Ratio of Two-Stage Helical Reducer with First-Stage Double Gearsets for Minimal Reducer Length

This article introduces a study on splitting the total gear ratio of a two-step helical reducer with the first step double gear sets. In order to do that, an optimization problem with the objective is the minimal length of the reducer was carried out. Moreover, the effects of several parameters containing the total gear ratio, the allowable contact stress, the output torque and the face width coefficient were investigated. For examining the relation between the partial gear ratios and the input parameters, a simulation experimental work was performed. Besides, the models for splitting the total reducer gear ratio were found.
