A herringbone gear, a specific type of double helical equipment,[1] is a particular type of gear that is a laterally (not in person) mixture of two helical gears of opposite hands. From the top, each helical groove of this gear looks like the letter V, and several 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 advantage of transferring power smoothly because more than two teeth will be in mesh at any moment in time. Their advantage over the helical gears is usually that the side-thrust of 1 half is well balanced by that of the other half. This means that herringbone gears can be utilized in torque gearboxes without requiring a considerable thrust bearing. Because of this, herringbone gears had been an important step in the intro of the steam turbine to marine propulsion.
Precision herringbone gears are more difficult to manufacture than equivalent spur or helical gears and consequently are more costly. They are used in heavy machinery.
With an intensive capacity to manufacture herringbone (or double helical) gears in quantities from huge to small, HZPT Co. can be well-prepared to meet up 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-period scheduling systems. Our die forming, temperature treating, machining, and finishing services are available to cover all guidelines of the apparatus production process, from begin to finish.
We feature an considerable material selection, including plastics, nylon, phenolic, alloy steels, aluminum, brass, and bronze. Common industries that we serve include pumps, pulp and paper, machinery, HVAC, and food processing, as well as many others. From casting to forging and beyond, we Herringbone Gear utilize the ideal gear forming method for your application and production order.
