1. Herringbone gears have a high degree of overlap, and at least two teeth are engaged at any time.

2. The meshing process between the teeth of herringbone cylindrical gear is an excessive process, and the force on the teeth is from small to large, and then from large to small; Herringbone gear has high bearing capacity and stable operation.

3. The herringbone tooth theory has no or only a small axial force, because the spiral angles of the teeth are opposite in the symmetrical direction.

Shortcomings of herringbone gears:

A very obvious disadvantage of 1. herringbone gear is that it is difficult to process. Herringbone gears can't be machined by conventional gear slotting and hobbing methods.

2. The cost of manufacturing more precise herringbone gears is too high, which can only be used for heavy equipment.

Application of herringbone gear;

Herringbone gears are generally used for heavy equipment with high reliability requirements, such as steam turbines. Did you find that the logo of a French brand is a bit like herringbone teeth? Yes, the early automobile transmission used herringbone bevel gears.
