A herringbone gear, a specific kind of double helical gear,[1] is a special type of equipment that is a side to side (not in person) mixture of two helical gears of opposing hands. From the top, each helical groove of the gear appears like the letter V, and several together form a herringbone pattern (resembling the bones of a seafood such as a herring). Unlike helical gears, herringbone gears usually 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 benefit over the helical gears is certainly 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 needing a substantial thrust bearing. Due to this, herringbone gears were an important step in the launch of the steam turbine to marine propulsion.
Precision herringbone gears are more difficult to manufacture than comparative spur or helical gears and therefore are more expensive. They are found in heavy machinery.
With an extensive capacity to produce herringbone (or double helical) gears in quantities from large to small, HZPT Co. is usually well-prepared to meet up your production needs, whatever the application form may be. Working 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-time scheduling systems. Our die forming, temperature treating, machining, and completing services can be found to cover all methods of the gear production process, from start to finish.
We feature an considerable materials selection, including Herringbone Gear plastics, nylon, phenolic, alloy steels, light weight aluminum, brass, and bronze. Normal 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 use the ideal equipment forming way for your application and production order.
