1) Features of herringbone gear
a) Identical teeth are cut in two halves of the gear blank maintaining same module, number of teeth and helix angle but opposite hand of helix.
b) Thrust force produces by each half of the gear is equal and opposite in direction; and thus they cancel out each other.
c) Absence of thrust force gives the provision to use higher helix angle (up to about 45°).
d) Since thrust force does not exist, so bearings that can handle heavy radial load can be used with herringbone gear.
