    PA 66 spur gear durability improvement with tooth width modification

    AbstractUnder heavy loading and large numbers of revolutions, the most commonly encountered gear damage is the thermal damage that is caused by an accumulation of heat on the surface of the tooth. The maximum Hertzian surface stress occurs at the single tooth pair contact region. The aim of this study was to delay the formation of thermal damage in the region of single tooth meshing by decreasing the Hertzian surface pressure by increasing the tooth width. The F/b (N/mm) tooth load was decreased in the single tooth pair contact region. Experiments show that the appearance of thermal damage is delayed for the width-modified gear teeth in comparison with unmodified gear teeth.
