A herringbone gear, a specific kind of double helical gear,[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 top, each helical groove of this gear looks like the letter V, and several together type a herringbone pattern (resembling the bones of a fish like 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 maintain mesh at at any time in time. Their benefit over the helical gears is that the side-thrust of one half is balanced by that of the spouse. This means that herringbone gears can be used in torque gearboxes without needing a substantial thrust bearing. Because of this, herringbone gears had been an important part of the launch 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 used in heavy machinery.
With an considerable capacity to manufacture herringbone (or double helical) gears in quantities from large to small, HZPT Co. is usually well-prepared to meet up your production requirements, whatever the application form may be. Employed in ratios up to 1 1.5 diametrical pitch and modules up to 20, we can produce herringbone gears measuring up to 60″ in diameter and 18″ in face width. We can also produce little parts, and provide as-needed and just-in-period scheduling systems. Our die forming, high temperature treating, machining, and completing Herringbone Gear services can be found to cover all techniques of the gear production process, from start to finish.
We feature an intensive material selection, including plastics, nylon, phenolic, alloy steels, aluminum, brass, and bronze. Regular industries that we serve include 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 the application and production order.
