Abstract:
By analyzing the examp les of drive gear tooth
2
breakage of the gear pair of retard turnk in PG6531B calcine air turbine
2
No. 1, the characteristics, positions and damage of the initial pitting, destructive p itting and surface spalling of the gear surface are analyzed,while, by finite elementmethod
2
modeling, the failuremechanism, influencial factors and the reasons for the occurrence of the fatigue of gears in cantact are discussed briefly, and some app rop riate preventive measures are suggested for the related gear
surface failures.
