A herringbone equipment, a specific kind of double helical equipment,[1] is a special type of gear that is a side to side (not face to face) combination of two helical gears of opposing hands. From the very best, each helical groove of this gear looks like the letter V, and several together type a herringbone pattern (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 maintain mesh at any moment in time. Their benefit over the helical gears is usually that the side-thrust of one half is well balanced by that of the other half. This means that herringbone gears can be used in torque gearboxes without requiring a considerable thrust bearing. For this reason, herringbone gears were an important part of the launch 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 costly. They are used in heavy machinery.
With an considerable capacity to manufacture herringbone (or double helical) gears in quantities from large to small, HZPT Co. is certainly well-prepared to meet your production needs, whatever the application form may be. Working in ratios up to at least one 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 little parts, and offer as-needed and just-in-time scheduling systems. Our die forming, temperature treating, machining, and completing services can be found to cover all actions of the apparatus production process, from start to finish.
We feature an comprehensive material selection, including plastics, nylon, phenolic, alloy steels, aluminium, brass, and bronze. Usual industries that we serve consist of pumps, pulp and paper, machinery, HVAC, and food processing, as well as many others. From casting to forging and beyond, we use the ideal gear Herringbone Gear forming method for your application and production order.
