Herringbone Gear

A herringbone gear, a specific kind of double helical gear,[1] is a particular type of gear that is a side to side (not face to face) combination of two helical gears of reverse hands. From the very best, each helical groove of the gear appears like the letter V, and several together type a herringbone design (resembling the bones of a fish such as a herring). Unlike helical gears, herringbone gears usually do not produce yet another axial load.
Like helical gears, they have the benefit of transferring power smoothly because more than two teeth will be in mesh at at any time in time. Their benefit over the helical gears is definitely 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 needing a considerable thrust bearing. Due to this, herringbone gears had been an important step in the introduction of the steam turbine to marine propulsion.
Precision herringbone gears are more difficult to manufacture than comparative spur or helical gears and consequently are more expensive. They are used in heavy machinery.
With an intensive capacity to produce herringbone (or double helical) gears in quantities from large to small, HZPT Co. is Herringbone Gear certainly well-prepared to meet your production needs, whatever the application form may be. Employed 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-period scheduling systems. Our die forming, temperature treating, machining, and completing services are available to cover all steps of the apparatus production process, from start to finish.
We feature an considerable materials selection, including plastics, nylon, phenolic, alloy steels, aluminum, brass, and bronze. Normal industries that we serve include pumps, pulp and paper, machinery, HVAC, and food digesting, as well as numerous others. From casting to forging and beyond, we utilize the ideal gear forming way for the application and production order.
