Herringbone gears conduct power and motion between non-intersecting,
parallel axis that may or may not have center groove with each group
making two opposite helices. The two helix angle come together in the
center of the gear face to form a 'V'. In these gears the end thrust
forces cancel themselves out. Its difficult to cut this type of gear but
its made easier by machining a groove in the face at the point of the
apex of the 'V' creating a break in the middle of the herringbone gear
teeth. They do not have any separating groove between the mirrored
halves. Materials of Construction

Applications of Herringbone Gear
The most common application is in power transmission. They utilize curved teeth for efficient, high capacity power transmission. This offers reduced pulsation due to which they are highly used for extrusion and polymerization. Herringbone gears are mostly used on heavy machinery.
