Herringbone Gear
A herringbone gear, a specific type of double helical gear, is a special type of gear that is a side-to-side (not face-to-face) combination of two Gear#Helical, helical gears of opposite Helix#Handedness, hands. From the top, each helical Groove (engineering), groove of this gear looks like the letter V, and many together form a herringbone pattern (resembling the fish anatomy#Vertebrae, bones of a fish such as a herring). Unlike helical gears, herringbone gears do not produce an additional axial load. Like helical gears, they have the advantage of transferring power smoothly, because more than two teeth will be enmeshed at any moment in time. Their advantage over the helical gears is that the side-thrust of one half is balanced by that of the other half. This means that herringbone gears can be used in torque gearboxes without requiring a substantial thrust bearing. Because of this, herringbone gears were an important step in the introduction of the steam turbine to marine propul ...
