How do you design a gear?

What is helical gear?

Helical gears are one type of cylindrical gears where the teeth are curved into a helix shape. Compared to spur gears (straight teeth), properly designed helical gears can have a larger total contact ratio which can improve vibration and noise. Badly designed helical gears can be noisier than well designed spur gears.

How do I select helix angle for helical gear?

Helix angles vary from 5° to 45°. Single-helical angles fall between 5° and 20°, and double-helical angles fall between 20° and 45°. Helix angles are selected to obtain a minimum overlap ratio and to provide good load sharing.
