A herringbone equipment, a specific kind of double helical equipment,[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 very best, each helical groove of the gear appears like the letter V, and many together type a herringbone pattern (resembling the bones of a fish like a herring). Unlike helical gears, herringbone gears 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 at any time in time. Their benefit over the helical gears is usually that the 
side-thrust of 1 half is balanced by that of the other half. This implies that herringbone gears can be utilized in torque gearboxes without requiring a considerable thrust bearing. For this reason, herringbone gears had been an important step in the intro of the steam turbine to marine propulsion.
Precision herringbone gears are more challenging to manufacture than equivalent spur or helical gears and therefore are more costly. They are found in heavy machinery.
With an intensive capacity to produce herringbone (or double helical) gears in quantities from huge to small, HZPT Co. is certainly 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 provide as-needed and Herringbone Gear just-in-time scheduling systems. Our die forming, heat treating, machining, and finishing services can be found to cover all guidelines of the gear production process, from start to finish.
We feature an extensive materials selection, including plastics, nylon, phenolic, alloy steels, aluminium, brass, and bronze. Normal industries that people serve consist of pumps, pulp and paper, machinery, HVAC, and food processing, as well as numerous others. From casting to forging and beyond, we utilize the ideal gear forming way for the application and production order.
