What are gears and what are the different types of gears?

Question

Accepted Answer

Gears are mechanical devices that transmit motion and power between rotating shafts. There are various types of gears including spur, helical, bevel, and worm gears.

Gears are mechanical components with teeth that mesh with each other to transmit motion and power.
Spur gears are the most common type, with straight teeth parallel to the gear axis.
Helical gears have angled teeth for smoother and quieter operation.
Bevel gears have cone-shaped teeth and are used to change the direction of rotation.
Worm gears consist of a screw-like gear (worm) that meshes with a normal gear, providing high gear reduction ratios.
