A Study on Development and Application of Load Distribution Program for Low-noise Straight Bevel Gear Design and Analysis

This study presents the development and validation of a novel load distribution program (LDP) for the design and analysis of straight bevel gears in differentials, specifically targeting the reduction of noise under high-speed operating conditions. By integrating various factors influencing gear performance, including tooth load distribution, tooth contact pressure, and transmission errors, the LDP enables comprehensive analysis and optimization of gear design parameters for enhanced durability and noise reduction. A prototype bevel gear designed using LDP demonstrated a significant noise reduction of over 10 dBA compared to existing production gears when manufactured using a forging process. These findings validate the effectiveness of the LDP in achieving optimized gear designs. The enhanced design capabilities empowered by LDP provide researchers with greater flexibility in developing innovative reducer and transmission structures.
