Herringbone Gear

A herringbone equipment, a specific type of double helical gear,[1] is a special type of gear that is a laterally (not face to face) mixture of two helical gears of reverse hands. From the top, each helical groove of this gear appears like the letter V, and many together form a herringbone pattern (resembling the bones of a seafood such as 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 any moment in time. Their advantage over the helical gears is certainly that the side-thrust of one half is balanced by that of the other half. This implies that herringbone gears can be used in torque gearboxes without requiring a Herringbone Gear substantial thrust bearing. Due to this, 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 therefore are more expensive. They are used in heavy machinery.
With an considerable capacity to produce herringbone (or double helical) gears in quantities from huge to small, HZPT Co. is well-prepared to meet your production needs, whatever the application form may be. Working 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 can also produce small parts, and provide as-needed and just-in-time scheduling systems. Our die forming, temperature treating, machining, and completing services can be found to cover all guidelines of the gear production process, from start to finish.
We feature an considerable materials selection, including plastics, nylon, phenolic, alloy steels, aluminum, brass, and bronze. Common industries that people serve consist of 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.
