A herringbone equipment, a specific kind of double helical equipment,[1] is a particular type of gear that is a laterally (not face to face) mixture of two helical gears of reverse hands. From the top, each helical groove of the gear appears like the letter V, and many together type a herringbone design (resembling the bones of a fish such as a herring). Unlike helical gears, herringbone gears usually do not produce an additional axial load.
Like helical gears, they have the benefit of transferring power smoothly because a lot more than two teeth will be in mesh at at any time in time. Their advantage over the helical gears is that the side-thrust of 1 half is balanced by that of the spouse. This implies that herringbone gears can be used in torque gearboxes without needing a substantial thrust bearing. For this reason, herringbone gears were an important step in the intro of the steam turbine to marine propulsion.
Precision herringbone gears are more difficult to manufacture than comparative spur or helical gears and consequently are more expensive. They are found in heavy machinery.
With an comprehensive capacity to manufacture herringbone (or double helical) gears in quantities from huge to small, HZPT Co. is usually well-prepared to meet up your production requirements, whatever the application form may be. Working in ratios up to 1 1.5 diametrical pitch and modules up to 20, we can produce herringbone gears measuring up to 60″ in diameter and 18″ in face width. We can also produce little parts, and provide as-needed and just-in-period scheduling systems. Our die forming, heat treating, Herringbone Gear machining, and finishing services are available to cover all actions of the gear production process, from begin to finish.
We feature an comprehensive material selection, including plastics, nylon, phenolic, alloy steels, light weight aluminum, brass, and bronze. Usual industries that people serve include pumps, pulp and paper, machinery, HVAC, and food processing, as well as many others. From casting to forging and beyond, we use the ideal equipment forming way for the application and production order.
