Abstract

This paper describes an inherent weakness that will be present on carburised gears when flank and root finish grinding is combined with the application of tooth edge chamfers. Results are presented from fractography performed on failed teeth from flank and root finish ground carburised gears which showed a propensity for bending fatigue crack initiation from the tooth edge chamfers during pulsator testing. Results are also presented from an initial investigation into methods of preventing such failures as controlling the detrimental aspect of tooth edge chamfers will allow the full potential strength benefits of modern gear manufacturing processes to be realised.
