Disaster Investigation of Idler Gear

Abstract

This paper addresses the failure analysis of idler gears in automotive and other mechanical systems. It aims to investigate the causes of gear failures and assess the effects of various heat treatment processes on gear materials.

The analysis covers gear applications, failure mechanisms, and the impact of heat treatment on the mechanical properties of steel. It includes a study of different heat treatments like annealing, normalizing, hardening, and tempering, and their effects on microstructure
