Herringbone Gear

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) combination of two helical gears of opposing 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 usually do not produce an additional axial load.
Like helical gears, they have the benefit of transferring power smoothly because more than two teeth will maintain mesh at any moment in time. Their benefit over the helical gears is that the side-thrust of 1 half is Herringbone Gear balanced by that of the other half. This means that herringbone gears can be used in torque gearboxes without needing a considerable thrust bearing. For this reason, herringbone gears had been an important part of the intro of the steam turbine to marine propulsion.
Precision herringbone gears are more challenging to manufacture than comparative spur or helical gears and consequently are more expensive. They are used in heavy machinery.
With an comprehensive capacity to produce herringbone (or double helical) gears in quantities from huge to small, HZPT Co. can be 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 can also produce little parts, and provide as-needed and just-in-time scheduling systems. Our die forming, high temperature treating, machining, and completing services can be found to cover all methods of the gear production process, from begin to finish.
We feature an extensive material selection, including plastics, nylon, phenolic, alloy steels, light weight aluminum, brass, and bronze. Common industries that people 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 equipment forming way for your application and production order.
