What is a herringbone gearing?
In herringbone gearing, the teeth are arranged in an arrow shape. In this case, herringbone gearing is also called double helical gearing. In contrast to straight and helical gearing, herringbone gearing is suitable for achieving the lowest possible pulsation while pumping. The arrow-shaped arrangement of the teeth improves the feeding behaviour on the one hand and leads to a significant reduction in pulsations on the other. The herringbone gearing is preferably used when a low-pulsation and gentler pumping of the medium is required, which is not guaranteed when using a helical gearing. In addition to the low pulsation, high efficiencies are also achieved with this application.
