A herringbone gear, a specific kind of double helical equipment,[1] is a special type of gear that is a laterally (not face to face) mixture of two helical gears of opposite hands. From the very best, each helical groove of this gear looks like the letter V, and many together type a herringbone pattern (resembling the bones of a fish such as a herring). Unlike helical gears, herringbone gears do not produce yet another axial load.
Like helical gears, they have the benefit of transferring power smoothly because a lot more than two teeth will maintain mesh at at any time in time. Their advantage over the helical gears is definitely that the side-thrust of 1 half is balanced by that of the spouse. This implies that herringbone gears can be Herringbone Gear utilized in torque gearboxes without needing a considerable thrust bearing. For this reason, herringbone gears were an important part of the intro of the steam turbine to marine propulsion.
Precision herringbone gears are more difficult to manufacture than comparative spur or helical gears and therefore are more expensive. They are found in heavy machinery.
With an comprehensive capacity to manufacture herringbone (or double helical) gears in quantities from large to small, HZPT Co. can be well-prepared to meet up your production needs, whatever the application may be. Employed 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 are able to also produce small parts, and provide as-needed and just-in-time scheduling systems. Our die forming, temperature treating, machining, and finishing services can be found to cover all techniques of the apparatus production process, from start to finish.
We feature an comprehensive material selection, including plastics, nylon, phenolic, alloy steels, light weight aluminum, brass, and bronze. Common industries that we serve include pumps, pulp and paper, machinery, HVAC, and food processing, as well as numerous others. From casting to forging and beyond, we use the ideal gear forming method for your application and production order.
