Özet

This paper presents a failure analysis of a hypoid pinion used in differential system of a truck. The hypoid pinion had been in service about two years when several teeth failed. An evaluation of the failed hypoid pinion was undertaken to assess its integrity. This included a visual examination, photo documentation, chemical analysis, micro-hardness measurement and metallographic examination. The failure zones were examined with the help of a Scanning Electron Microscope (SEM) equipped with EDX facility. Results indicate that the teeth of the hypoid pinion failed by destructive pitting and severe spalling because of overloading. Copyright © 2011 Inderscience Enterprises Ltd.
