Herringbone Gear

A herringbone gear, a specific type of double helical gear,[1] is a special type of gear that is a side to side (not in person) combination of two helical gears of opposite hands. From the top, each helical groove of this gear looks like the letter V, and many together type a herringbone pattern (resembling the bones of a seafood like 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 benefit over the helical gears is definitely that the side-thrust of one half is balanced by that of the spouse. This means that herringbone gears can be utilized in torque gearboxes without requiring a substantial thrust bearing. Because of this, herringbone gears were an important step in the introduction 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 found in heavy machinery.
With an intensive capacity to manufacture herringbone (or double helical) gears in quantities from large to small, HZPT Co. is certainly well-prepared to meet your production requirements, whatever the application 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 small parts, and offer as-needed and just-in-time scheduling systems. Our die forming, high temperature treating, machining, and finishing services are available to cover all techniques of the gear production process, from start to finish.
We feature an comprehensive Herringbone Gear materials selection, including plastics, nylon, phenolic, alloy steels, light weight aluminum, brass, and bronze. Regular industries that people serve consist of pumps, pulp and paper, machinery, HVAC, and food digesting, as well as many others. From casting to forging and beyond, we utilize the ideal gear forming method for your application and production order.
