Abstract

This paper investigates the complex interaction between material selection, heat treatment processes, and strength calculation methodologies in the design of gear transmissions. The mechanical performance and durability of gears are highly dependent on the choice of base material and the subsequent thermal treatments applied to optimize their microstructure and mechanical properties. We analysed how different heat treatment techniques, such as carburizing, quenching, and tempering, influence the microstructural characteristics and fatigue strength of common gear materials. Furthermore, the study evaluates how these material and heat treatment factors are integrated into strength calculation models used in gear design to predict operational lifespan and reliability. Experimental data and numerical simulations are employed to validate the correlation between processing parameters and gear performance. The findings highlight the critical role of a holistic design approach that considers material properties, heat treatment parameters, and accurate strength calculations to enhance gear transmission efficiency and longevity.
