Description
Summary:This study investigates the relationship between various gear design parameters, including the helix angle, number of teeth on pinion, addendum modification coefficient & gear ratio with a focus on balanced specific sliding. Utilizing iterative solutions to the design objective function, configurations were selected with number of teeth on pinion of 16, 18, and 20, helix angles ranging from 12 to 18 degrees, and gear ratios of 2, 3, and 4. The obtained values were subsequently analyzed and validated against these configurations using graphical representations of balanced specific sliding. The key findings offer valuable information on how these parameters affect gear performance and tooth profiles. Additionally, this paper introduces new MATLAB-based optimization program tailored for balancing specific sliding ratios in involute helical gear tooth profiles with long-short addendum system. Leveraging the AGMA 913-A98 standard equation, the MATLAB program ensures the effective balancing of specific sliding through mathematical modeling and optimization techniques. By iteratively adjusting gear geometry, the MATLAB mathematical program achieves a uniform specific sliding ratio. The results, presented in charts, offer valuable guidance for researchers and engineers involved in helical gear design.This study emphasizes how optimizing gear configurations and balancing specific sliding ratios can enhances wear performance and operational efficiency in gear box used for ball milling process, benefiting manufacturers and operators.
