A herringbone equipment, a specific type of double helical gear,[1] is a special type of equipment that is a laterally (not face to face) combination of two helical gears of opposite hands. From the very best, each helical groove of this 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 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 benefit over the helical gears is definitely that the side-thrust of 1 half is balanced by that of the spouse. This means that herringbone gears can be utilized in torque gearboxes without needing a considerable thrust bearing. Due to this, herringbone gears were an important part of the introduction of the steam turbine to marine propulsion.
Precision herringbone gears are more challenging to manufacture than comparative spur or helical gears and therefore are more expensive. They are found in heavy machinery.
With an intensive capacity to produce herringbone (or double helical) gears in quantities from large to small, HZPT Co. is certainly 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 provide as-needed and just-in-period Herringbone Gear scheduling systems. Our die forming, temperature treating, machining, and finishing services can be found to cover all guidelines 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 digesting, as well as numerous others. From casting to forging and beyond, we 
utilize the ideal gear forming method for the application and production order.
