1) Description of Herringbone Gear Shaft
Herringbone Gear 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.
2) Applications of Herringbone Gear Shaft
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.
