Width modification for gears with low contact ratio

In this study, teeth width modification on spur gears with low contact ratios is introduced. The modification essentially relies on maintaining constant Hertz surface pressure along single and double teeth profiles. With this aim, adjustments were made in tooth width along the single mesh area. It is intended that, with this modification, negative effects caused by high Hertz pressures along the single mesh area will either be minimized or completely removed.
