A Herringbone Gear herringbone equipment, a specific type of double helical gear,[1] is a special type of equipment that is a side to side (not face to face) combination of two helical gears of opposite hands. From the very best, each helical groove of the gear appears like the letter V, and several together type a herringbone pattern (resembling the bones of a seafood like a herring). Unlike helical gears, herringbone gears do not produce yet another axial load.
Like helical gears, they have the benefit of transferring power smoothly because a lot 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 were an important step in the launch of the steam turbine to marine propulsion.
Precision herringbone gears are more challenging to manufacture than equivalent spur or helical gears and consequently are more costly. They are used in heavy machinery.
With an considerable capacity to produce herringbone (or double helical) gears in quantities from large to small, HZPT Co. is certainly well-prepared to meet your production requirements, whatever the application may be. Employed 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 offer as-needed and just-in-period scheduling systems. Our die forming, heat treating, machining, and finishing services are available to cover all methods of the apparatus production process, from start to finish.
We feature an extensive material selection, including plastics, nylon, phenolic, alloy steels, aluminium, brass, and bronze. Usual industries that people 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 gear forming way for your application and production order.
