COGWHEEL Meaning and
Definition
-
A cogwheel, also known as a gear, is a mechanical device composed of a circular toothed wheel that meshes with another toothed wheel or chain. It is commonly used in machinery and engines to transmit and control power or motion between rotating shafts. Cogwheels are frequently made of metal, such as steel or brass, and are found in various sizes and shapes depending on their specific application.
The teeth on a cogwheel are evenly spaced and are designed to fit and interlock with the teeth of another cogwheel or chain, allowing for smooth rotation and efficient transfer of power. This interlocking mechanism prevents slippage or disengagement during operation and ensures precise synchronization and transmission of motion.
Cogwheels have been utilized for centuries and are essential components in a wide range of mechanical systems. They are employed in machinery such as clocks, bicycles, automobiles, and industrial equipment, where they play a crucial role in controlling speed, torque, and direction of rotation. Cogwheels are also employed in many manufacturing processes, allowing for the precise and synchronized movement of components and enhancing overall system efficiency.
The design and arrangement of cogwheels within a system determine the overall gear ratio, speed, and power transmission capabilities. By varying the number, size, and arrangement of cogwheels, different levels of mechanical advantage can be achieved, enabling the adaptation of power and motion for specific applications.

Etymology of COGWHEEL
The word "cogwheel" originated from the combination of two Old English words, "cog" and "wheel".
The term "cog" comes from the Middle English word "cogge", which meant a type of tooth or projection. It was derived from the Old Norse word "kugg", meaning a cog or a tooth on a gear. The Old Norse word was borrowed from the Proto-Germanic word "kuggô".
The word "wheel" has its roots in the Old English word "hweol", which referred to a circular object that rotates on an axis. It can be further traced back to the Proto-Germanic word "hwewlaz".
Combining these two words, "cog" and "wheel", resulted in the word "cogwheel" to describe a toothed wheel that engages with other gears or cogs to transmit motion and power.
