Gears : Double Helical Gears
A Double Helical Gear is also known as a herringbone gear. It can be thought of as two identical helical gears of opposite hand fused together so they share a common rotational axis. This design equalizes the axial thrust forces inherent in a single helical design, eliminating the need for a substantial thrust bearing.
