Abstract

In many different devices, gears enable the efficient transfer of motion and torque. They are an essential component of modern mechanical power transmission systems. It has been demonstrated that bending and surface contact stresses at the gear tooth are the primary causes of gear failure, despite their widespread use. Too much stress can lead to tooth wear, pitting, or breakage, which can ultimately reduce the operating life and reliability of the system. In order to improve gear performance, extend service life, and prevent early failure, accurate stress measurement has become a crucial area of research The current study focuses on evaluating contact and bending stresses in an involute helical gear system. Both analytical methods and numerical simulations are employed to provide a comprehensive understanding of gear behavior under load. To establish a baseline for the stress distribution over the tooth profile, the analytical analysis makes use of the traditional Lewis bending equation. In addition to offering a platform for comparison in more intricate numerical investigations, this method offers an initial assessment of important stress sites To achieve more precision, ANSYS, a powerful numerical simulation program that is perfect for structural and contact problems, is used to perform finite element analysis (FEA). To construct the three-dimensional gear models required for FEA, Pro/Engineer, a sophisticated solid modeling program, is utilized. Models with varying tooth counts are constructed in order to examine the effects of geometry on stress concentration and design parameters on gear performance. ANSYS and Pro/Engineer work together to enable precise stress field evaluation, providing insights that surpass the limitations of purely analytical methods The comparison of analytical and FEA data illustrates the benefits and drawbacks of the Lewis formula in predicting actual gear stresses. Although analytical approaches are faster and easier to use, finite element modeling better captures the complex geometry and loading conditions, yielding results that are more consistent with real-world observations. The findings demonstrate the importance of numerical simulations in gear design and optimization, particularly in high-load situations where reliability is essential All things considered, this work demonstrates the significance of integrating finite element analysis and analytical equations in the design and evaluation of helical gears. The findings guide the selection of appropriate design parameters, enhance gear reliability, and lower the likelihood of failure in mechanical power transmission systems.
