A tooth (plural teeth) is a small, calcified, whitish structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness.
In an industrial or manufacturing context, "tooth" refers to a projecting edge or ridge on a gear, saw, or other mechanical component. The term is often used to describe the shape and size of these ridges, which are designed to interact with other gears or components in a specific way. Here are a few examples of the use of "tooth" in this context:
-
Gear teeth: The ridges on the circumference of a gear that mesh with other gears to transmit power and torque.
-
Saw teeth: The sharp, jagged edges on a saw blade that cut through material.
-
Spline teeth: The series of ridges on a splined shaft or component that interlock with corresponding ridges on a mating component.
-
Rack and pinion teeth: The ridges on a rack that mesh with the teeth on a pinion gear to convert rotary motion into linear motion.
-
Toothed belt: A belt with teeth on the inside surface that interlock with corresponding teeth on a pulley to transmit power.
These are just a few examples of the use of "tooth" in an industrial context, and there are many other types of mechanical components that use this term.
