1) Features of Helical Gears
The teeth of a helical gear are set at an angle (relative to axis of the gear) and take the shape of a helix.
This allows the teeth to mesh gradually, starting as point contact and developing into line contact as
engagement progresses. One of the most noticeable benefits of helical gears over spur gears is less noise,
especially at medium- to high-speeds. Also, with helical gears, multiple teeth are always in mesh,
which means less load on each individual tooth. This results in a smoother transition of forces from one
tooth to the next, so that vibrations, shock loads, and wear are reduced.
