A Herringbone Gear herringbone gear, a specific kind of double helical equipment,[1] is a special type of gear that is a side to side (not face to face) mixture of two helical gears of opposite hands. From the top, each helical groove of this gear appears like the letter V, and many together form a herringbone pattern (resembling the bones of a fish like a herring). Unlike helical gears, herringbone gears do not produce yet another axial load.
Like helical gears, they have the advantage of transferring power smoothly because a lot more than two teeth will maintain mesh at any moment in time. Their advantage over the helical gears can be that the side-thrust of one 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. Because of this, herringbone gears had been an important part of the launch of the steam turbine to marine propulsion.
Precision herringbone gears are more challenging to manufacture than equivalent spur or helical gears and consequently are more expensive. They are used 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 may be. Employed in ratios up to 1 1.5 
diametrical pitch and modules up to 20, we are able to produce herringbone gears measuring up to 60″ in diameter and 18″ in face width. We are able to also produce small parts, and offer as-needed and just-in-period scheduling systems. Our die forming, heat treating, machining, and completing services can be found to cover all methods of the gear production process, from begin to finish.
We feature an comprehensive materials selection, including plastics, nylon, phenolic, alloy steels, light weight aluminum, brass, and bronze. Typical industries that we serve include pumps, pulp and paper, machinery, HVAC, and food digesting, as well as numerous others. From casting to forging and beyond, we utilize the ideal equipment forming way for your application and production order.
