Herringbone Gears

Herringbone Gears

Herringbone Gears - A right and left hand helical gear side by side form the herring bone gear. Originally, a herring bone gear consisted of two helical, gears one right hand and other left hand but today, most herringbone gears are produced as a single unit on special machines which cut the teeth in two directions at one time.

The herringbone style neutralizes the end thrust and makes a strong, quiet gear. Since such gears have a greater bearing surface, they possess exceptional/tool strength and heavy load carrying capacity. They stand up under continuous high speed operation better than other gears.

Cutting herringbone gears is slower and more difficult, so they are most frequently used in the larger size, especially for heavy machinery. Herringbone gear is sometimes called a double helical gear.
