Optimization of A Two-Stage Helical Gearbox with Second Stage Double Gear Sets to Reduce Gearbox Across Section Area and Enhance Gearbox Efficiency

Abstract

The goal of this research is to look into multi-target optimization of a two-stage helical gearbox with second stage double gear sets (SSDGS) in order to find the most critical design parameters for minimizing gearbox cross section area and enhancing gearbox efficiency. In two phases, the Taguchi technique and grey relation analysis (GRA) were used to address the problem. The single-objective optimization issue was faced first to narrow the separation between variable levels, and then the multi-objective optimization problem was solved to determine the optimal primary design variables. The first and second stage CWFW coefficients, allowable contact stresses (ACS), and first stage gear ratio were also calculated. The study's findings were utilized to identify the best values for five critical design parameters of a two-stage helical gearbox with SSDGS.
