- Spur Gears: The simplest and most common type. It provides motion transfer between parallel shafts.

- Helical Gears (Helical Gear): Works quieter, can transfer higher loads.

- Bevel Gears: Transmits movement at 90 degrees or different angles.

- Rack and Pinion Gear: Converts rotary motion into linear motion.

- Worm Screw and Wheel System: Provides large speed reduction and high torque transmission, usually used in lift or crane mechanisms.
